MFOS | Alien Screamer

Description

The MFOS Alien Screamer circuit consists of three main components: a voltage controlled oscillator, a low frequency oscillator and a one watt amplifier that drives a small speaker. The unit is powered by one nine volt battery and due to the low current drain of the LM324 it gets a lot of miles out of a nine volt battery.

There's no time like the present to start that hobby you've wanted to get going for years. This is a great project for beginning your synth-diy journey or if you're already building sound gear this is a great project to make for that imaginative young person in your life. It's a great introduction to synth-diy (the oscillator is a ramp core driven by an exponential V to I convertor). 

Don't expect to play this as a traditional instrument (although it does a decent imitation of a theremin in the right hands) but do expect to have a lot of creative, imaginative sound making fun. From star trek communicators to birds tweeting you'll find a wealth of coolness.

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.
