HackMe Electronics Sprockit Mini-Synth


via HackMe Electronisc

"Rockit’s getting a little brother, Sprockit. My goal with Sprockit it to take a lot of Rockit goodness and compress it down to something smaller and a bit cheaper. I’m achieving both goals by having a very dense design and by reducing some of the features...

Sprockit will be fully open source just like Rockit.

Two oscillators – Just like Rockit, except there’s only one knob. I have initially made 32 oscillator settings which chooses both oscillator 1 and 2 and the oscillator mix at the same time. Oscillator 2 still has a detune knob.

4-pole Analog Low Pass Filter – Instead of Rockit’s three-mode filter, I’ve given Sprockit a 4-pole Low Pass only filter. I’m experimenting with automatic gain control, but I’m making no promises and there are some reasons not to have it. Filter envelope control is accessible externally. There is no external audio input like Rockit.

1 LFO with 3 waveshapes and 3 destinations, with more shapes and destinations accessible externally.

ADSR envelope with Attack and Decay control on board and everything else externally accessible

MIDI Input – No MIDI output."
