Experimental user-defined pattern for arpeggiator
Merge branch 'master' of github.com:patrickdowling/preenFM2 into experimental
Show user pattern editor row only when active
Rename engineApr to engineArp (probably just a typo)
Store user arp pattern (contents might still change though)
Store arpeggiator patterns in a uint32_t instead of 4 floats, allowing for 4 per timbre. Add specific editing code (rough implementation)
User Pattern
Add fancy pattern edit modes using encoders 2+3
Makefile 1.B12 + KSyn display fixe bug (4.00 correctly displayed)
