Been working on this part of my patcher for a while and a bit stuck.

I'm making a playback system. Chords come in from the frontend (not in realtime), which will be connected to timepoints. I want the machine to work out how long each chord lasts for. So for example:

^ the dm7 has 3 rests following it, so can conclude it last for 4 beats. The Cmaj7 has 7 rests following it so can conclude it lasts 8 beats

I've found a way to represent chords with zero, and the following beats to show numbers representing the gaps ahead, so the above becomes:

I need to now convert this so the zero becomes the length of the harmony for each chord, so the above would become:

(First two chords last 4 beats, third chord lasts 8 beats).

Hard to explain, but will prob make more sense when you see the patch. I've labelled it with comments to help clarity.

Why this complicated counting ? seems a simple task.

When you detect a chord, reset counter to 1 and count till next detection appears.

Detected beats till next chord make a leading number, than you append number or zeroes

So if for example Dm7 did not change for 11 beats, than

nn - 1

P.S. if all you want is to convert that list

Thanks for your reply. Sorry, i didn't respond at the time because I didn't entirely understand your reply. Looking at it again, i think i understand the issue. You're treating it as realtime question, but it's actually a instantaneous process which maps the harmony onto the 'page' so when realtime events occur via transport, they react to it.

I actually think i've found a way around anyway by using colls for the harmony, so it can query any timepoint, but if that doesn't work out maybe i'll come back on here. But anyway, I wanted to say thatnks for taking the time to respond.
