I am trying to create a patch where the number of midi notes on at any one time determines the number of splits (scissors) to a jitwindow. Each note will trigger its own video loop.

So, I need to know [how many notes are on] and [which ones], notify me when this changes with a new list that outputs [new notes and the deleted notes] to [turn on new loops and turn off the deleted ones] and [how many notes are on now].

I think I can manage the jit.scissors and glue part once the midi analysis is done, but I can't figure out what midi and list objects to use to analyze the midi data.

polyopticon

The Borax object does a lot of useful tracking on a MIDI note stream.

Here's an example of a simple sequencer using Borax that may give you some ideas:

You just need to analyse the velocity of [notein] and count the one 

Note that noteon with a 0 velocity is considered as a noteoff in all 

keybaords I know, although a real MIDI noteoff is a different code.

Thanks - that will do the current number of notes on to send to scissors. just need to know which ones are on etc... maybe borax will help

is there an equivalent jitter object to MAX's forward object?

I need to reassign "voice allocation" when "polyphony" is reduced.

the problem is when rows and cols in jit.glue decrease, an active incoming matrix at a higher inlet number than the number of rows or columns is not automatically reassigned to an inactive inlet within the row/column range.

It would be good if I can send the matrix to a variable destination like the forward object.

It would be good if I can send the matrix to a variable destination like the forward object.

Did you try, oh, I don't know..."forward'?

I thought 'forward' only took messages not matrices - oh man! I've been staring at it for hours trying to find a work around - argghhh!

thanks - yup it works, though the voice reassignment is shaping up to be trickier than I thought.

sorts list of voices (actually a matrix) into value order, then out of coll to be reordered by the 'counter' as voice 1 to 10 where any voice that has a value of 0 will be given an index greater than the number of active voices. 'Gate' distributes the new voice number to the new indices. The new voice numbers are then evaluated by the umenu as a message to prepend the forward object. This should send the voice (matrix) to the appropriate 'receive' object <<< I think>>> problem is - it doesn't - not sure where the mistake is as no matrix exits the outlet
