From c4aca7b81e76e0f098ac0f855599bdf1e3cf1e22 Mon Sep 17 00:00:00 2001

Subject: Improved: Midi initializations. New settings options, can be 'quiet'.
 Complete rewrite of initializations coding. Improved: Midi controller graphs:
 Control selector 'S' popup now stay-open, AND NOW with multi-coloured dots.
 Bonus! Pianoroll and drum edit 'Ctrl' buttons ALSO now popup this very same
 menu. Improved: 'Old' drum track 'drum controllers' display and operation:
 Fixed several problems.
