Midi sync start/stop on pattern first step

[Chab]

>> We had considered making the All button stop/restart all motifs. Would that help?
Yes, that would help when playing the NDLR as master clock. Since we have 1 button, maybe a customizable option would be even more flexible for all users (e.g. "play restarts from step 1: on/off")

As for MIDI slave, this is the expected behavior i guess:
- "stop" message received: stop playing but remembers current position (in case next message is "continue")
- "continue" message received: resume playing from current position
- "start" message received: restart playing from step 1
