The outputs from both decade counters will be routed to two rows of eight output channels. Each channel features a potmeter for CV adjustment and a step indicator LED. Individual gate outputs will be added at a later stage.

Major rethink! After several trials, I've decided to mount the potmeters and LEDs directly on a panel and not on PCB's. They got too crowded and it would have been almost impossible to repair. Instead I will use bits of stripboard as wiring posts. Simple does it.
