Atomic Gold Beta is a 4 oscillator, 8 LFO, bi-filtered, 3 ADSR, phase-distorted synth with variable feedback unit, tweakable velocity sends and aftertouch control. It's many functions make it a powerful device to synthesize anything from heavy basses to organs and lush synths to deep LFO effects. This kind of control for free is little short of ridiculous! And if that's not good enough, the source code is available on request.
