I need some more details. Does the MS-404 trigger correctly via Midi but the
pitch does not change In this case I assume that something is wrong with
the pitch CV between the Midi interface and the VCO (maybe a defective
digital-to-analog converter). Did the MS-404 work before or did you buy it
second hand

If it helps: the MS-404 service manual is available on our website (>
MANUALS > user's guides of older devices > MS-404).

Best wishes
