I'm trying to create a MIDI effect in M4L that filters the velocity of MIDI notes according to how often they occur. My attempt to make this happen currently involves using a histo object to store how many times each key has played in what I'll call a 'counter' table, which dumps its data to another table for storage. The 'counter' table and histo object are reset per bar ready for the next bar of MIDI data to be inputted, and the stored table functions as a kind of frame, which is averaged with the next frame of data received and stored again, and this procedure is repeated every bar. Once I've got that working I hope to be able to map how often a key has been occurring on average against a filter curve to look up a new velocity for each key received to then be output with - sorry if that was poorly communicated.

To average each value of the newly received table with the currently stored table, I get the values for each index in both tables, average each pair, store the results in a third 'average' table, which I then dump into the stored table upon completion. My problem is with timing the transfer of data between tables. Instead of using the table's dump message, which seems to dump values too immediately to work with, I'm counting through each MIDI key index with an uzi and counter, and although the patch is basically doing what I want, imperfections in the timing of it all creates problems in the output average table. *Phew, that was hard to express!*

Anyway here's the code, any help or advice would be very gratefully received.
