"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.
The board features PC mounted pots for less wiring, and mounting holes for flexibility in panel layout. There are Eurorack and MOTM power connecters. It can be built in +/-12V or +/-15V systems with no modifications.
Here
is an mp3 demo demonstrating a few randomly generated patterns
from just hitting the "new pattern" button.
Here
is an mp3 demo demonstrating the differences in musical modes,
pattern lengths, rhythmic subdivisions and pitch range
Here
is an mp3 demo demonstrating the difference in straight rhythm
and random rhythms. It also features some drum sounds in the
background to help give the rhythms a better context. Only the auto
seq is manipulated in this mp3.

Boards are available now. Price for 1 PCB/PIC set is $20.
Unfinished eurorack
panels are available for this project, they are 12HP and cost $8 each.
There is
more information here about panels. If you're interested in drilling your own panel for
this project, feel free to use my
drill guide. That image should be printed at 300dpi for proper
scaling.
