explore_overtone's Issues

[Question] How do I get started?

Hi,

Thanks for collecting and providing these examples - they are diverse and very cool!
I'm looking at the maze example specifically. Excuse my possibly silly question, but: how would I go about "running" that code? It's not its own namespace so I couldn't find a way to load in a repl, aside from copy pasting each function into it. What is the starting point?

Thank you & thanks for taking care of this repo!

vr-metronome beat->time->beat mismatch

I've found some sort of bug in my code. It turns out that if I get the time for a beat from (vr-metro-time m beat) and then use that time to find the beat via (vr-metro-beat m time), they don't match for a simple linear transition (60bpm -> 120bpm over 10s). So, there's something wrong here. At this point, I think that vr-metro-time gives me the proper time for the beat, but vr-metro-beat does not give me the proper beat from the time. But, I'm still investigating.

I created vr-metro-beat from vr-metro-now-beat when I saw the issue....

(vr-metro-beat [metro ticks]
"convert ticks (in ms) to a precise floating-point beat value. Not a whole number."
(integrate @bps-fn 0 (* 0.001 (- ticks @start)))) ;; time in seconds, not ms
(vr-metro-now-beat [metro]
"convert (now) to a precise beat value"
(vr-metro-beat metro (now)))

local repo instructions

Sam suggests "use lein's checkout feature" which is likely far more easy than my current instructions. give it a try.

update midi event handling

Sam explained on-event/on-sync-event/on-latest event here:

https://groups.google.com/forum/?fromgroups#!topic/overtone/_ssmymRBUJc

I think note-on/note-off wants on-sync-event.

control events want on-latest-event.

upgrade issues

maze, piano - no sound -- is overtone.inst.piano broken?

piano - inst-fx -- couldn't find that?

quil_display -- no 'start' for metronome?
