[sdiy] DOTCOM Analog Sequencer.. next project startup..

If you're going to go with a rotary encoder, why not use a single one with
N-number of buttons, one per step.  You could get a really high quality
encoder for less than 16 decent analog pots.

Hold the button down, a display shows what note is programmed there, and
turning the encoder adjusts that note.

Your firmware could allow multiple notes to be adjusted at once even.
