i don’t think there is a specific key-combo for playback from the first pattern (atleast not bound to any shortcut)
either doubleclick the arrow in the pattern matrix (single click queues the pattern) for the first pattern or use arrows (when the pattern matrix is highlighted) or ctrl + arrows (if you are in the pattern editor) to go to the first pattern and hit space/r-ctrl/r-alt. (might work with pgdn/pgup to go directly… dunno. i’m at work right now)
eh, not the best explanation there… hope that helps.
thanks! didn’t know you could use home/end-keys with the Ctrl-command as well. i just clicked the first pattern, or used Ctrl-Up/Down. this will save me a bit of time.
