Transitions for 3/4 and 3/2 track speeds. #117

Closed jmamma closed 4 years ago

jmamma commented 4 years ago

Will likely need to rethink how track transitions works. We currently calculate next transition in 16th step resolution.

This won't work for 3/2 and 3/4 tracks because they run at 0.75 and 1.5 speed.

For example:

Pattern length is 16 steps. At 3/4 speed, the next transition will occur on (1/0.75) * 16 == 21.333 steps.

Sequencer will go out of sync...

Proposed solution. Each track to have a transition_offset, measured in mod12 ticks. Transition start can be shifted by 0 -> 12 ticks

transition_offsets added.

Still going out of sync... with MD sequencer on transitions.

Transitions for 3/4x 3/2x now working via track offset method described above.

Question: Should the offset be reset to 0 if transitioning back to a standard 1x, 2x scale. Answer: MD does not reset clock offset, if switching between patterns of different scales.
