DM10 "Calibration Fail" on start up & other problems
« on: October 03, 2025, 11:54:27 AM »
Hi there,
Very new here, I've bought an Alesis DM10 Studio kit recently for my little home studio.
I'm not a drummer at all and I never had an electronic drum kit. And although I've read the many
posts here on the forum, it's extremely difficult for me to set this kit up without having ghost notes,
the ride cymbal playing all by itself in EZDrummer 3 (since yesterday, didn't happen before) and then some ...

As soon as I power up the module, I always get the same error message "Calibration failed". Even though I did calibrate
the Hi-Hat pedal. I'm going directly via MIDI to my PC to trigger EZDrummer 3 (I also have SSD 5.5 and the whole lot of NI Komplete Ultimate drums, though haven't tried any of these yet).

The kit is mounted with mesh heads, the original skin heads were supplied with the kit.
Hitting the snare i.e. doesn't always trigger the drum, depending on where I hit there might be no sound at all.

To eliminate the ghost notes I get whenever hitting an element, I set up the sensitivity and threshold of the pads
in a way that I get no more rimshots. It's really making me crazy.

Maybe some of the experienced members could help me out, guide me through some trouble shooting procedures?
I'm also going to try out the 2 trigger setting presets found in that other thread, to see if it gets a little better.

TIA,
Ralf ;)

Welcome to the Forum !

Typically the Calibration Fail is the Crash Cymbals are switched..Input 7 and 11 (only one input supports Choke) this was common at the time or the Incorrect Power supply... which should be 9V AC 1.5Amp.

In regards to the Triggering...check the OS Version etc.
There was an update (Final) for Mesh Heads when the Mesh Kits were released , otherwise the Firmware is for the Mylar Heads.
The question I have is...was there actually  a Mesh Conversion performed..or simply slapped on Mesh Heads..

The original Mylar Kits had the Piezo very close to the Head and the Mesh conversion moved the Piezo down in the stack.
If the conversion wasn't done then the triggering is probably going to be too hot and you'll have to adjust/lower all of the settings and try to dial out the issues.

The Final Versions
DM10 Firmware Updates [posted 9/22/2014]
DM10 Updater 1.00
DM10_boot_v1.00h.syx
DM10-app-v1.00s.syx
DM10_triggers_V1.00a.syx (use with real hat pedal)
DM10_triggers_V1.01b.syx (use with Alesis Pro-X hi hat)
DM10_sound_rom-V1.03.syx

DM10  Firmware Updates [posted 9/22/2014]

Boot, App, Trigger, and Sound ROM firmware updates that improve overall performance of the DM10 module
Increases sensitivity, reduces the possibility of crosstalk, and enhances system stability.

Adds default trigger settings for the DM10 X Kit Mesh and the DM10 Studio Kit Mesh drum kits


If your Module is up to date..check which Kit has been initialized.

The Final Update also added/allowed you to choose between (4) Kits under the menu..(2) Mylar..(2) Mesh.
The Studio Kits had 8" Toms.

Initializing the Default Trigger Settings
(for DM10 Studio Kit, DM10 Studio Kit Mesh, DM10 X Kit, and DM10 X Kit Mesh only)

Once your DM10 module is updated, initialize the default trigger settings to the correct kit before playing.
1. Power on your DM10 module.
2. Press the Utility button.
3. In the screen that appears, choose F4 (Sys).
4. On the next screen, choose F2 (Init).
5. Use the Cursor Down button to highlight the Trigger Settings option and then press
the F4 (Exec) button.
6. On the next screen, use the Cursor Down button to highlight your drum kit and then
press F1 (Exec).
Your DM10 module will return to its Main Screen.
It is now set to the default trigger settings for your Alesis drum kit.

EDIT:
The 9/22/2014 update is in the DM10 Mesh kit downloads..DM10 Studio Mesh..DM10 X Mesh..
I just checked the downloads as it has been quite awhile and Alesis has been migrating everything (including Legacy) to the New Alesisdrums site..
The Mylar Kits are still active with product pages and downloads..ALL Info pertaining to the Mesh Kits have been removed and the Product link takes you to the New Alesisdrums Kit Lineup..they want to sell you a New Kit.
All of the Firmware is relatively small so they can be added here....it is the Sound ROM that is over 100MB and would require hosting.

Hi Chaser,

Thank you very much for the detailed walk through.
I think all is up to date on the brain, however last time I checked on the Alesis website
the one update (the latest) was not to be found. Now that you say it is under the DM Studio Mesh downloads,
I'll check again.

I don't know if a Mesh conversion was done on the kit, as the guy I bought it from didn't have any clue.
He couldn't play either. And I've never seen a message asking what kind of kit I was using.

I'll try again over the weekend to find the latest update, install it and see where it goes from there.

I'll keep you posted about my success (or no success  ;D )

Have a good night,
Ralf

Hi again Chaser,

For the life of me, I can't get to the 9/22/2014 FW download. As you said, the Mesh kits redirect you to the main (new) drum kits page.
The last FW I can find is 8/5/2014.

I tried with Google Chrome & Firefox, no dice.

Do you have that latest FW by any chance? Or are you able to download it and send it to me by PM/mail?
I do have all the other files ... (sound ROM etc.)

Have a great weekend,

Ralf

The Sound ROM hasn't changed for years...you would probably require it only if your Module has never been updated since around 2012.

As I mentioned before double check all of the Versions currently in the Module.

1. Press UTILITY to enter the main Utility Menu.
2. Press SYS (F4) to access the Accompaniment settings.
3. Press O/S (F3) to access the operating system information page.
4. This page contains the version numbers of the module's current software:

a. Trig OS: The current version number of the trigger
firmware.

b. Sound ROM: The current version number of the sound ROM the library of sounds read by the module.

c. Sound OS: The current version number of the module's own firmware
(Sound OS  = app)

The Final update was released over 10 years ago and unless your module was a "closet" module and never used , they usually are updated.
There are topics/post in the Forum from Horror stories of users trying to force things  or unnecessary update and ended up bricking the module.

Typically you would start from scratch after purchasing a module..do a factory reset..then Re-Initialize and select a Kit.
You would then be starting fresh as everyone has a different style and/or plays different.

There are two ways to reset the DM10:

To fully restore the module to original factory settings, hold the EXIT and STORE  buttons while powering on the module.

To reset only the kits, sequences, or trigger settings:

    Press UTILITY to enter the main Utility Menu.
    Press SYS (F4) to access the Accompaniment Settings.
    Press INIT (F2) to access the reinitialization page.
    Use CURSOR UP/DOWN to move through the following menu items:
        All Kits: All of the modules kits and their settings will return to factory default
        All Sequences: All of the modules sequences and their settings will return to factory default
        All Trigger Settings: All of the modules trigger settings will return to factory default
        Highlight the option you would like to reset, then press EXEC (F4).
       A window will appear asking you to confirm your choice. To confirm and reinitialize the selected settings, press YES (F1).
      To Cancel, press CANCEL (F2 or F2).

If you can re-Initialize and it shows (4) Kit options..the module is up to date DO NOT ATTEMPT TO UPDATE
(it is/was only update to add the 4 Kit option) and you only need to select the correct Kit for Trigger settings.
The Studio Kits had/have 8" Toms..the DM10X Kits were 10/10/12/12.
Early DM10 Kits (Pre-Mesh 2014/2015) did NOT have the Sensitivity Knob and had/have a different trigger system (reflection plate)

Initializing the Default Trigger Settings
(for DM10 Studio Kit, DM10 Studio Kit Mesh, DM10 X Kit, and DM10 X Kit Mesh only)
Once your DM10 module is updated, initialize the default trigger settings to the correct kit before playing.
1. Power on your DM10 module.
2. Press the Utility button.
3. In the screen that appears, choose F4 (Sys).
4. On the next screen, choose F2 (Init).
5. Use the Cursor Down button to highlight the Trigger Settings option and then press
the F4 (Exec) button.
6. On the next screen, use the Cursor Down button to highlight your drum kit and then
press F1 (Exec).
Your DM10 module will return to its Main Screen. It is now set to the default trigger
settings for your Alesis drum kit.

I attached a zip of everything except the Folder is empty for the Sound Rom..
Keep in mind the Updater app is XP era...
Do NOT attempt to Downgrade (example:go from Pro-X back to Realhat Pedal)...you may end up with a Blank Screen..see this Topic which also has the step by step instructions.

The Old DM10 Update Video (NoteRepeat) is still active

Hi Chaser,

In spite of having tried to follow to the letter your instructions, I'm not getting much further.
A little bit better nonetheless regarding the ghost notes, the "Calibration fail" message
apparently coming from the Crash 1, which has a mono to stereo cable (TR -> TRS).
Seems strange to me, in my book one should either use TR->TR or TRS->TRS cables, no?

After setting all Xtalk send/receives to 0, I still get double triggers of other sounds,
or the module triggering sounds all by itself in EZDrummer 3 without touching any element of the drums.
I can't get no rimshot, ride choke (it's supposed to be possible, ain't it?) and I'm pulling out my hair (what's left of it  ;D )
A couple of days ago I spent like 3-4 hours trying to figure it out ...

One of my major problems is the lack of time, I'm working Monday to Saturday usually, having 2 rehearsals a week and a family life ...

Today I should find some time to try the 2 trigger presets from that other thread (Tsints & ProbeGT) and see if it gets any better.
An btw, thank you for the firmware. I also asked for it with Alesis support who kindly provided a download link.
As it turns out, everything was already up to date on my module. So I'm able to choose one of four kits after after a factory reset (which doesn't change anything
in regards to my trigger problems, it's either no hit recognized or triggering other sounds at the same time).

Maybe I should mount the original Mylar heads which were included by the guy I bought the kit from.

I'll report back how it goes. Have a great weekend,

Ralf

If I recall the Crash one input is a single zone with choke. That requires a TRS->TRS cable to work. The "Calibration fail" message might be because the cable you are using is grounding out the choke signal. So, the module might think the choke switch is closed when powering on. To test this I would unplug the crash one cable from the module and then power on module to see if you still get the "Calibration fail" message (Again, make sure you remove the cable from the module's jack). If you don't get the message then the issue is your cable. You will need to switch to a TRS->TRS cable. Of course that assumes your crash trigger has a true TRS connection in it.

Seems strange to me, in my book one should either use TR->TR or TRS->TRS cables, no?

Cables are TS(Tip/Sleeve) or TRS(Tip Ring Sleave..there is no Tip/Ring cable.
Crash 1 - Input 7 is Dual Zone and You MUST use the correct Crash Cymbal , which as mentioned previously..they are often Mixed up.
The DM10 kits came with 3 types of cymbals,  (2) single zone, (1) dual zone, and (1) triple zone.
Depending on the Kit you had different sizes and also different zone count for the size..
DM10 STUDIO 3-12" (2 single, 1 Dual Zone) , 1-14 Dual Cable (Triple Zone)
DM10X 1-12(Single Zone-HI HAT),2-14 (1 Dual Zone,1 Single Zone-CRASH) ,1-16 Dual Cable (Triple Zone-RIDE)
To use the Choke function of the Drum kit, you'll need to be using the Dual or Triple Zone connected to the module via TRS cables.

Crash 2 - Input 11(PERC3) and is Dual Zone NO Choke....PERC3 RIM Must be set to SWITCH.

ALL Cables for the DM10 are/were TRS with the exception of the included cables for the Kick,Hi Hat and Hi Hat Controller which are/were TS.
As pointed out by Hellfire...the Input is being shorted and the Module thinks the Cymbal is Choked so Calibration failure.
Change to TRS and if using DMPad Cymbals check underneath and see if the label is still there.
It needs to be a Dual Zone Cymbal..NOT Single Zone.

The Kick Input(1) is actually Dual Zone TRS and can be split using a TRS to TS Cable.
You then assign the Kick RIM to another Kick Pad (set RIM = PIEZO) and have a Double Kick or another option is a Pedal that uses a Switch like a DMHat V1.(set RIM = SWITCH)
You can then use the Foot Pedal as a Kick (SWITCH = NO Velocity) or set to do one of a variety of Functions..Prev Kit..Next Kit..Tap Temp..etc.You can setup this Feature for unused Trigger/Zone under the Trigger settings.
(Refer to manual pg 24).




Alesis DM10 | Troubleshooting Common Trigger Problems

Calibration Error On Boot


Scenario: You open the DM10 kit for the first time and you are following the assembly guide on setting up your kit. Once that process is complete and you turn on the unit, you receive a message stating: "Calibration fail Try rebooting with drums unplugged or without touching them".

1. Turn off the module, go to the back of the module, and disconnect all of the cables on the top row.

2. Turn on the module, if you are still getting the same message, repeat step 1 but with the cables on the bottom row. if you did not receive the calibration error message then continue to step 3.

3. Turn off the module and look carefully at the tip of your cable snake. Each cable has a color-coded label to help you connect it to the correct pad.  Please be sure that the red label reading "CRASH" is connected to Port 7 on your module and your 14" dual-zone pad. This is the most common mistake.

4. Finally, turn the module back on, and the module should calibrate properly.

Cymbals are not choking

On DM10 Kits, only the Crash and Ride ports have the choke feature.
Perc 2-4 are Dual Zone ports that will support additional dual drum pads or single zone cymbal.

If you're having trouble triggering the choke on your crash or ride, ensure that they are connected to the correct ports using the provided TRS cables (TS will not work).
The choke-able cymbals will have a rubber trigger area that extends around the edge and underneath the cymbal, creating a grip.
The Choke function will only work when grabbing this portion of the cymbal.

Quote
After setting all Xtalk send/receives to 0, I still get double triggers of other sounds,
or the module triggering sounds all by itself in EZDrummer 3 without touching any element of the drums.

O (Zero) doesn't mean Zero Crosstalk..
Refer to the Manual pg 25

A couple of days ago I spent like 3-4 hours trying to figure it out ...

Rimshot is the Rim Zone..check on screen to make sure it is triggering when hit there is a row of circles bottom LCD.... the center ring is head..outer ring is rim..solid black is rim being triggered when hit..if triggering then check for articulation/sound assigned..not all kits have a rimshot assigned.
If the RIM Zone isn't triggering then you have a Bad Piezo..Bad TRS cable or a single Zone Pad.

The Ride is a Dual Cable TRS..using (2) Inputs (RIDE1/RIDE2) and Factory Default set to 3 Zones and Choke.
If it is set to Dual Zone (Bow/Bell) you use a single TRS Cable and you must use a Dummy Plug and there is NO Choke.
Depending on which cymbal output the Dummy Plug is placed determines if the Edge switch or Bell switch Triggers  the Bell.
Using a Single Cable opens up another Trigger Input for use (9-RIDE2/PERC1)

One of my major problems is the lack of time, I'm working Monday to Saturday usually, having 2 rehearsals a week and a family life ...

Can't help you there..you get out of it what you put into it..It is definitely not plug-n-play.
being New to E-Drums and a Kit with DIY Mesh Conversion along with an advanced drum Module is going to require time especially jumping right in and using Vst/Software.

Prior to EZD3 , EZD2 and Previous you had to Re-Program the Module for each and every EZ Drummer expansion as they all used different MIDI Maps.I haven't setup a DM10 with EZD3 so can't comment on the Mapping , however Note the DM10 sends Choke Notes..NOT Aftertouch.

Quote
Today I should find some time to try the 2 trigger presets from that other thread (Tsints & ProbeGT) and see if it gets any better.

There is No Universal trigger setting or any guarantee that others trigger settings will work any better for you..even a little bit.You often end up spending more time adjusting without knowing if the custom user settings are for the exact same Kit setup as your own (Trigger System..Trigger sizes..Mesh Head Ply etc), than starting from the Modules factory defaults so that if you mess up or forget to save you are back to square one..you start off at the same Parameters when you Factory Reset..otherwise you have to connect computer and re-load user Trigger Presets.
It's like getting into a car to drive with the seat adjusted for someone else.
Everyone plays differently and different style , along with going from an acoustic to electric requires an understanding that you can't approach/ play an E-kit like you do an Acoustic...entirely different even stick size makes a difference.

As it turns out, everything was already up to date on my module. So I'm able to choose one of four kits after after a factory reset (which doesn't change anything
in regards to my trigger problems, it's either no hit recognized or triggering other sounds at the same time).

Maybe I should mount the original Mylar heads which were included by the guy I bought the kit from.

Have you checked to see if the Mesh Conversion was actually performed or an aftermaket conversion installed?
There's a good chance that like the module update it may have been...then again it may have been skipped and only the Heads were changed to Mesh.Over the years I have seen examples of all 3.
The update trigger settings are/were for Dual Ply Mesh Heads.
There are different Mesh Plies available..1,2 and 3 Ply and some aftermarket conversion Kits were only Single Ply...some used a Cone.

Just like a simple check for the Update in the Module and the 4 Kit option..you would have known in less than a few mins...without knowing exactly what you have you are just spinning your wheels and could be spending time (which you already stated you don't have much of) adjusting trigger settings for the wrong kit or user Trigger settings selected.One of the best uses for the little time you have is to become familiar with the Manual..
ALL Drum modules are TMI (Trigger To MIDI).
You make all of the MIDI adjustments in the Module and the MIDI is sent to Sound Sources..either Internal (LOCAL CONTROL ON) Sound Generator or external (LOCAL CONTROL OFF) Hardware/Vst/Software.
If the Module is setup up properly and sounds good..chances are so will the Vst/Software which some Vst/Software Developers have added features for additional adjustment to their software..others did not.

Many thanks again to the both of you, @hellfire & @chaser,

I understand that it's not simply plug 'n play with an electronic drumkit. And I'm willing to put in the time it takes
to fully understand and configure the kit.

I guess I'll start completely new and take it from there, one step at a time.

How can I check this ? A part from the mesh heads (TAMA), all pieces seem to be original.

I had to change the 2 crash cymbals and have no more "Calibration fail" error on startup. First step of success ...

UPDATE:
After much poking around, I'm getting much, much closer.
I have re-adjusted the whole kit with a first trigger setup, adjusting carefully xtalk snd/rcv, zone-talk (where applicable)
and I have much less xtalk already. What's more, I do have rimshots on snare and toms (even though it's still not where I'd like it to be),
chokes on cymbal and ride kind of work (I have to grab them quite firmly).

I'll save the trigger setup as sysex on my PC, so to not lose them and have a starting point, in case I have to start over.  :-X

How "hard" has the mesh to be tuned? 2 of my toms don't trigger as well as the other two or the snare. Touching the heads,
those who trigger better have less tension then those who don't trigger that well ...

Well, anyways, I'm getting closer thanks to your help/walkthrough. Sometimes all that's needed, is another perspective on things.

Thank you very much, once again.

There were many conversions over the years..Hellfire came up with the original Mesh Conversion...basically the Foam is rearranged and the Piezo is placed deeper in the Shell.You could also remove the resistors on the Jacks if needed.
The Mylar Kits had a very thin piece of Foam on top of a Metal Plate.
If it is a Hellfire Mesh Conversion you would see a Thicker piece of Foam on Top..maybe some Eva Foam also and if you lift the Metal Plate you would typically see the foam had a circle cut in the center.

The other popular conversion at the time was the 682Drums which was cone and everything was gutted and the Conversion Kit came with 682 Mesh Heads.Pearl had single Ply Mesh Heads available.682Drums closed recently..there were out of the Netherlands

https://682drums.com/

There were other methods as time went on..there are many versions of Mesh Conversion/Comparison posts in the Forum.

The Heads around 76/77lbs...if you use a Drum Dial.

Alesis added a support page including Video...for more recent Heads/Trigger Systems.

Alesis Drums | Do my mesh heads need to be tuned?

Tuning a mesh drum head is done in the same cross shaped motion as a a regular drum head, until the head is tight enough that you can't press into the center with your thumb with moderate pressure and create an impression.For proper tuning technique, please see the following video:

The foam inside the pads may start to deteriorate and lose rebound etc over time also

There is/was the DM10 Editor..an Open Source project...support ended many years ago,however I posted the Final Versions etc

Introducing DMEditor

EDIT:
I forgot to mention...
The Module sets the Global Trigger Sensitivity to MEDIUM after a Factory Reset.
You can set it to HIGH and see if the Rims etc are better.. then go through and Adjust/lower the sensitivity individually on whichever pads you think are now too Sensitive.
Utility > F3 > LOW/MEDIUM/HIGH
