Stoev Lab has released Projection, a dual geometrical sequencer / CV recorder module for VCV Rack based on geometric transformations. It can generate two variable-length sequences, chain and transform them in several ways, producing new musical material. It can also record two CVs and do the same with them.
Use it as a sequencer, a CV recorder/looper, or a stepped modulation source. Even try it as a wavetable oscillator.
Price: $10. Works with VCV Rack.
