streamPause / UnPause, streamSeek, streamLoop

hush -> stops all patterns and cycle still cycles on, wonder if we could add to this...

• streamPause -> do not stop patterns, but cycle stops
• streamUnPause -> resume cycling, and patterns continue
• streamSeek n -> current cycle ± n (using setCycle?)
• streamLoop (a, b) -> loop cycle between points a and b

I think these would be really handy for composition! It would effectively give you full "transport" control in the DAW timeline sense.

streamSeek would be great for tracking down cycle ranges where a particular pattern sounds great.

streamLoop lets you loop a section of time that you're working on, as is common in a DAW.

Great ideas!!

Can you comment on the behavior when doing this in a session with Link peers? http://ableton.github.io/link/ has the terminology. Please think about beat alignment. Please also think about what to send to the Link API https://github.com/Ableton/link/blob/master/include/ableton/Link.hpp. If you feel like it, of course. I might give it a stab myself!

Hey, thanks, I'm actually really occupied playing gigs right now, but this thought just came to mind. Please feel free to explore this idea!

This variation of zoom achieves streamLoop to a degree:

zoomCycle :: (Time, Time) -> Time -> Pattern a -> Pattern a
zoomCycle (startCycle, endCycle) totalCycles pat = 
    let start = startCycle / totalCycles
        end = endCycle / totalCycles
    in zoom (start, end) pat
