ms404 scale

ms404 scale

2013-11-10 by aletropdj@yahoo.com

Hi all,


When I got my ms404 a few years ago I knew that was not calibrated, and today I got some time.
Because I couldn't calibrate, I found P2 pot was lose. It was desoldered and after fixing I could set the CV scale.
But in the end the cv out its 0.3v, 1.3v, 2.3v, etc...

any tip?

That may just be the way it is.  Other synths, sequencers, and convertors have a similar offset, which you can compensate for with the tune knob on whatever synth or VCO you at controlling.   The important thing is that the scale is 1V/Oct, which .3, 1.3, 2.3... is.

That's normal. The DAC used in the MS-404 had about 250...350mV offset. But
after all it does not matter as the absolute tuning can be adjusted by a
trimpot and the front panel control

Best wishes
