Need a starting point as I am getting nowhere with this! So near yet so far;-)

I need to produce a patch that has four looped midi files all of different lengths. For example MIDI file 1 has 3 beats file two has 5 file 3 has 7 and file four has 9 beats, they need only to have one note-on each that I can create a bang from, but they must be using the same base for tempo. All except the first file have note-on timing offsets i.e they start after the beginning of beat one.

the looping of the beats (not the notes) would look like this.

123123123123123123123123123123123123123123123etc

12345123451234512345123451234512345123451234512345etc

12345671234567123456712345671234567123456712345671234567etc

123456789123456789123456789123456789123456789123456789123456789etc

I have been trying to do this with four "seq" objects but the problem seems to be that it is difficult to create midi file type 0 with the exact lengths needed.

I suppose that what I am really asking is just for a starting point for a simple 4 track step-time sequencer where each track can loop with different lengths. I need to give a specific BPM too (this is really important).

I know this is not technically a support question but this is driving me mad. I have built a beautiful video engine in jitter that needs to be triggered in this way. I am reverse engineering some algorithmic music to be played back as video of clips of real people playing instruments. It will be crazy I promise!

I will post this on the forum once more so as to not be a total support leech. I don't like to hassle support but am a desperate composer/video artist and this one I am really exited about. 

If you got this far thanks for reading! :-)

You might try a "tempo" metronome object sending a bang to four "counter"

objects with different maximum counts. They'll count exactly what you have

listed below. Then for example use the "select" object to select different

You might try a "tempo" metronome object sending a bang to four "counter"
objects with different maximum counts. They'll count exactly what you have
listed below. Then for example use the "select" object to select different
notes at different times.

What you want to do is very easy with the iCE sequencing tools. Set 

up four ice.lattice objects with lengths 3, 5, 7, and 9 respectively

and bang them all from a common metro.

Thanks to all who replied with helpful advice. MIDI files were a joke compared to using tempo>counter>select. I now have a fully functioning poly-rhythmic event trigger for my jitter efforts!

The resolution of the events (notes) you need dictate the multiplier you use. I guess if you need more res than 16th notes you just subdivide the BPM. Then select just grabs the number you want for the note offsets as they come around in the counter.
