Hi there, my name is Elwin Molenaar, I'm from the Netherlands and I've purchased an old D4.
trying to see what model I have as apparently you can't adjust the Vcurve and Decay (and the likes) on an older version.......... seems like I got to older version...
To check which software version is installed in your unit, press the Drum Set button..... Let go... , then hold down BOTH the Cursor buttons < > at the same time.
The ROM version will be displayed for a few seconds.
Grab all the manuals etc
here ...
The OS software revision history can be found in the service manual on pages 16-17 (pdf pages 20-21)
The last version was 1.04...you can still get the ROM's cheap.I see some on Ebay Europe.
If you are starting everything from scratch you could do a Hard reset.It restores all of the ROM data to the factory specs.
Alesis D4 -Hard ResetPower down for a few minutes. Then hit the "voice" and "output" keys at the same time, and hold them both while you power up.
This will re-set the D4, and should clear up problems if any.
