ProtoPSG psg-005

8voice poly PSG like synth


Because this GUI development took long time, it is still incomplete. Im sorry for naked PCB. About sound, because this is PSG chip, sounds like 'pe pooh'. But now, because the filter function is added, ProtoPSG can generate not only PSG like sound.

the ProtoPSG.ini file like follows.

[midicc]
vol=7
pan=10
osc1vol=20
osc2vol=21
nosievol=23
