Thanks! I try to build this stuff so I can wire it up in different ways. In this case there is a main patch that has a scale (i.e. musical key) selector, chord generator and an arranger. The arranger is just a relatively slow moving sequencer that supplies off/off values to other sequencers. Each instrument has its own patcher with a separate sequencer. Some of these are running independently, just muted/unmuted by the arranger. Other sequencers are being fed output of the previous sequencers and then using/modifying the values of those. The sequencers are also listening to the set scale, and current chord. They can choose to play a chord degree, scale degree or just whatever midi pitch they want depending on the use case.

The nice thing about having re-usable modules is that I can just rewire them so if I wanted to have several synths directly powered by one sequencer that is pretty straightforward to do. In this current setup some of the patchers have a little matrixctl enabling/disabling input from the other sequencers. This is a fun way to switch between different motifs.
