The story continues:
this is the EURO-POCKET EDITION of the GB MULTI OSCILLATOR. it has all the features of the original version. the most important change is: it fits into a eurorack case. this is the first “working” prototype, i’ll update the gerbers and documenation (^^post above) once i’ve tested it a little bit more…
