drone box. it's a synth, basically. designed to make walls of tones and drones!
not really based on any existing circuit. it's a bunch of simple ideas that will all be wired together in weird ways. at first it was going to be pseudo-modular but decided I'd rather mess with well-planned switching and relays instead. here's how it basically functions:
6 oscillators each with a wide frequency range, fine-tuning and triangle-square shape control. sub brings the range down to literally pulsating textures (less than 1hz in frequency). the highest is ear-shattering/borderline off human-hearing. each oscillator can independantly and selectivly be pitch-modulated by either of the two sequencers. each sequencer can be hard-synched or independant. portamento blends the steps so that they flow more naturally if wanted. either sequencer can be set to loop or to be triggered. if triggered, it stops after the eighth step. each oscillator can be independantly panned (left to right) and mixed to a final stereo mix for potentially wicked awesome stereo soundscapes! the final stereo mix volume can be modulated by either of the two sequencers as well.
a bit of technical info: oscillators are opamp based. I use tl072s. sequencers are just 4017s. I use vactrols to modulate stuff around.
