Thank you, John! (Didn't know about the "A" designation ROM). Luis, I hope that John will help you.
I don't remember if my Matrix-6 has the "A" ROM in it, but I usually do the following after powering on and letting the M-6 warm up for about 10 minutes or so:
Run the CALIBRATION routine (MASTER setting, function 52). To get the best sound out of the Matrix, the CALIBRATION routine is necessary, as it not only tunes the DCOs, but also aligns the waves, pulse widths, VCf cutoff freqs., and sets the PITCH and MOD. levers to a zero point. BUT! Before running the CALIBRATON, work the PITCH and MOD. levers fully up and down a few times, letting them settle at the mid-point. That is where CALIBRATION will set the zero point for the levers.
NOW run CALIBRATION. It will ask "READY
" Press the "YES" key. You may hear some very quiet sounds as the adjustments are made. This will take about 15 seconds. When finished, the display will return to CALIBRATION. I usually press the TUNE button to insure that it's fully-tuned.
Often, this will 'cure' not-good sounds eminating from the Matrix-6/-6R.
Best of luck - Muy Buena Suerte!

Re: [oberheim] help with my matrix, from argentina!
Actually, you want 2.13A for the keyboard. The A version has a larger dead band for the pitch lever, so it comes back to centre better. I can provide the file, or I can provide the ROM for $50 plus shipping...
