"Auto-Seq" is shorthand for "Automated Sequencer." It is a unique step sequencer which programs it's own sequences. There is a small selection of controls to help refine it's sequences to the taste of the composer. There is no way of storing and recalling the sequences which it writes, Auto-Seq is an improviser. If you're interested in random composition, or if you're just tired of the hand cramps that come with programming traditional step sequencers, then this is a module that you might find useful.
This is for a PCB (including programmed microcontroller) only suitable for multiple formats.
