The Step Sequencer Project - Sequencer Controller

Sequencer controller front panel - click to enlarge

This is a preliminary design for the Sequencer Controller front panel, which will be aligned with the main front panel. (The design will be revised to match the main front design.) The sequencer controller will have four channels, each channel containing

Rotating encoder for setting the maximum number of steps for the channel
LED showing that the channel is currently active
LED showing that the channel is activated
Pushbutton for instant GOTO the channel
Switch to activate/deactivate the channel
TRIG IN jacks

In addition the controller will have

An LCD display showing the maximum number of steps set for each channel
Four audio CV IN jacks
One audio CV OUT jack
A switch selecting the desired number of channels (one to four)
One common TRIG IN jack
A switch selecting either separate TRIG IN pr. channel or common TRIG IN for all channels
Transpose controls (octaves/notes, not shown on front panel)

So far we're concentrating on a two channel implementation, with slightly reduced functionality (no transpose control, no GOTO). Here is a schematic showing the present design (click image to enlarge).
