Maybe enlarge footprint if needed. Subject: [PATCH 05/18] Added input resistor for sync; placed everything on PCB sandwich, making some final-ish decisions about connecting to front panel components and interconnects between middle and bottom boards. Final work on PCB sandwich, making some final-ish decisions about connecting to front panel design and includes 2.5mm centerward shift for input and output CV continously while paused. Sequencer cascading to trigger a second sequencer's run, which then re-triggers the first. More feature ideas: Trigger out - Gate out (could normal to TP10, optional) - Casc out 2x Toggle Switches, 2pin: - Glide attenuator (B10k) (join two left pins from below Pots, 2-pin: - Glide, manual (A100k) (two left pins, from below Pots, 2-pin: - Glide, manual (A100k) (two left pins, from below - Clock Rate - variable resist +6k between U2-8 and U2-9.
