ARP UI

[topisani]

We need UI for our ARP Engine. It is a fairly regular arpeggiator, with the following features:

• PlayModes: [up, down, updown, downup, updowninc, downupinc, manual, chord, random]
• Octave modes: [boring, +1, +2, +1 unison, fifth unison, -1 & +1]
• Note length: percentage of time to hold notes
• Subdivision of master clock: [quarter, quartertriplet, eighth, eighthtriplet, sixteenth]

We probably want to visualize the notes in some way, since some combinations of play modes/octave modes are quite complex.

I wrote some code for the previous iteration for an auto-scaling of dots to visualize the sequence. So if we somehow get the note-data to the screen, we could adapt that code.
