MFOS | Synth-DIY Experimenter Board


If you've been wanting to get started in synth-diy by building a cool sound effect box you can't do better than this project. You will have a veritable plethora of sound generating devices in the palm of your hand although I recommend some kind of case (last joke I promise). This board is packed with simple circuits that sound cool. You'll be surprised by the number of sound possibilities it supports. You don't have to build all of the modules either. You can just build what you want to make a specific sound. You want wind... just build the White Noise Generator and one VCF. You want better wind build the White Noise Generator both VCFs and the output mixer. How about birds or bell sounds... just build the Sound Effect Oscillators an AR Envelope Generator and an LFO. You can go as far as you like with this project.

Velocity As with a piano, the harder you hit a key, the louder the sound, unlike most organs which always produce the same loudness no matter how hard you hit a key. Aftertouch Pressing a key after you activated it. Channel Aftertouch, no matter which key, it will send a Channel message. Poly Aftertouch, sends the pressure per key instead of the whole channel.
Values for OSC, LFO, Filter, Envelope are per voice unless stated otherwise.
