Sequencer panel

This is close to the final panel for the sequencer. There are a couple of neat features which will be part of the production. The "RYM" switch connects the CV out of row "C" to the VC Clock input. This allows you to vary the clock rate by the output of the sequencer. The Run switch turns the internal clock on and off. The Stop switch is a little different. Normally, the Steps switch will select how long the sequence is and will reset to step 1 as soon as the sequencer hits the selected step. When the Stop switch is on, the sequencer will go through one sequence only and then stop and hold the selected step. So, if you set the steps to 6, the sequencer will play the first six steps then stop and hold on the sixth step. Reset manually resets the sequencer. When the Run switch is down, the Advance pushbutton simply advances the sequencer by one step to allow setting the CV voltage for the step or for manually advancing the sequence. The A/B switch can link row A to row B and gives you up to 16 steps for a sequence. The Gate/Reset switch and jack are interesting, too. When set to Gate, and the Stop switch is down, you can feed a key down gate signal into the jack and the sequencer will cycle through the sequence while the key is down and then stop when the key is up. If the Stop switch is on, the sequencer will cycle through one sequence, then stop and hold the last note while the key is down. It will do it again on the next key down. The Keyboard Sum adds the keyboard CV to the output of the sequencer row A (or row A and B if the A/B switch is on 16), so the sequencer output will track the keyboard. This is nice for setting up an arpeggio that maintains the right scale relationship to the key pressed.

OK, I think this is all correct. When everything is all tested, I'll make corrections if I need to.
