The GSi Krill Synthesizer was born from a design originally conceived to work as a mono synthesizer on an embedded processor (RP2040), then it was modified to be polyphonic for a more powerful processor (ARM H7) and finally we thought it would be perfect as a AUv3 for iPad, for those quick and dirty synth sounds you sometimes need without getting lost in endless parameter navigation and menu diving. So here it is, just one screen, one knob - one function, what you see is what you get. Two oscillators, one LFO, one low pass filter, two envelopes, stereo chorus, ping-pong delay, 64 presets. Have fun!
