Some old fracrack synth modules. The last is a Blacet Mixer Processor. The others are DIY. These DIY modules are
2 x 8 step sequencers. These are barebones they don’t have any quantization or even LEDs for the steps. These have a clock trigger out, forward backward switch, reset, and a carry out which can be used to chain them together.
A 10 step step sequencer it outputs a trigger at each of 10 steps. This has a clock out, and and end step which can be used to make shorter sequences.
2 x LFOs with triangle, square, saw, noise, and step out. These also have a sample and hold.
