here is a simple step sequencer / trigger that takes a variable bpm input.

it produces the same results as coges step trigger/seq patch although simplified and derived from different math.

basically i take the number 15/bpm gives you your 16th note duration which is used to delay a signal counter.

this works beautiful in unity as i am able to sync up lots of tracks.

qc hiccups a bit if your messing with the editor while its running.

probably best to use something like this for visuals rather than music.

Great thankin' you. I think that will be useful. Will have a look at the coge sequencer as well, is that within the app or already separate somewhere?

Re: step sequencer (Composition by dust)

sweet was wondering why the 16th notes where not triggering the way intended. i was thinking i didn't need to subtract 1 because the signal is triggering on start. how is the modulo helping to play the 16th notes.

fixed

why 'substruct-1'
first signal -> count up multiplexer ->can't trig source#0

but
use modulo ->first index source#15

change
count-1 <= 0 ? 0 : (count-1)%16

Here it is: http://www.quartzcompositions.com/phpBB2/upload/details.php?file=1410

This is really old, CoGe drives the sequencer from Cocoa from years ago.

BTW, here is a link to the latest CoGe version which was fully QC driven, newer versions are Cocoa+OpenGL driven: http://coge.lovqc.hu/forum/viewtopic.php?f=15&t=25
