I just got it Sample Rack works like a charm , also the hihat you can use them as normal sound, 8 sample via midi extra or 16 samples with velocity switch both 8 midi notes you can assign via midi.
Sd Cards enable velocity switch for each zone ( 2 sound per input trigger stated wrong on the User guide, it is clearly Each zone of each dual zone are Velocity switch A+B, up to 4 sound for each Trigger 1 to 7, 2 midi notes for each triggers 1 to 7.
With Sd Cards
Dual zone snare Each zone have 2 sound velocity switch sound A+B,+ 2 midi note (total of 4 sound each triggers + 2 midi notes triggers)
Tom triggers are Dual zone, Each zone have 2 sound velocity switch sound A+B,+ 2 midi note (total of 4 sound each triggers + 2 midi note each triggers)
Cymbals triggers are Dual zone, Each zone have 2 sound velocity switch sound A+B,+ 2 midi note (total of 4 sound each triggers + 2 midi note each triggers)
Kick one zone, 2 sound velocity switch sound A+B,+ 1 midi note (total of 2 sound)
-Without Sd Cards
Snare Dual Zone, 1 sound each zone (total of 2 sound),+ 2 midi notes
Tom triggers are Dual zone, 1 sound each zone (total of 2 sound),+ 2 midi notes each triggers
-Each Cymbals triggers are Dual zone, 1 sound each zone (total of 2 sound),+ 2 midi notes each triggers
Kick one zone, 1 sound one zone (total of 1 sound),+ 1 midi note
With Sd Cards
Hi Hat A:
Open; + 2 sound velocity switch sound A+B,+ 1 midi note
Mid ; + 2 sound velocity switch sound A+B + 1 midi note
Close; + 2 sound velocity switch sound A+B + 1 midi note
Hi Hat B:
Open; 2 sound velocity switch sound A+B +1 midi note
Mid; 2 sound velocity switch sound A+B +1 midi note
Close; 2 sound velocity switch sound A+B +1 midi note
HiHat Chick 1 midi notes, 2 sound velocity A+B
HiHat splash 1 midi notes, 2 sound velocity A+B
Hihat: Total of 8 midi note and 16 samples
Without Sd Cards
Hi Hat A:
Open;1 sound, 1 midi note
Mid 1 sound, 1 midi note
Close; 1 sound, 1 midi note
Hi Hat B:
Open; 1 sound, 1 midi note
Mid; 1 sound, 1 midi note
Close; 1 sound, 1 midi note
HiHat Chick 1 sound, 1 midi note
HiHat splash 1 sound, 1 midi note
Hihat: Total of 8 midi note and 8 samples
Each 8 or 16 sample Hihat can be played Via midi as a normal trigger or drum, no need to be hihat device, you can assign any sound to them... I plugged my Spd-SX and I play these 8 midi note separately on each spd-sx pad and all is fine like a drums.
Kick, 1 midi note, 2 velocity switch sound A+B
You can leave B empty if you want even with the SD cards installed
Without SD cards you have a Total of 23 sound and 23 midi note users kit
With SD Cards =46 samples sound with velocity switch or simultaneous and 23 midi note each users kit
There is more potential then the Sample Pad Pro, more layers capability on each zone and more sound. (Sample pad pro are limited to 8 one zone pad velocity switch)
I am very pleased with the Capability and specially the velocity switch for each zone, including the kick and the HIHat, I can trigs 8 samples or 16 velocity switch sound via midi for the hihat with any sound assigned to the hihat open,mid, close chick and splash works as trigger, could not ask more for this price. Hands Down way more potential then the Roland TM-2 for the same price.
Akai MPX8\ MPX16 are not the same as Sample Rack related to midi notes and sample for each users kits, without Sd cards 23 midi notes 23 sample each users kits or with Sd Cards, 23 midi note and 46 samples each users kits, more potential with Sample Rack!
Ps: Sample Rack Internal Sound Snare and Ride are build with velocity switch sound (Not related to Zone A+B) and without having SD cards.
