Making instruments and FXs in MaxMSP/M4L and Osmose : trying to figure out the basics

I assume with full MAX you could see the entire Haken Editor and see how everything is done and communicated.

I’ve made first steps towards that; opening the .maxpat files in a text editor and modifying them to let me unlock the patches / NOT hide and disable all of the toolbars.

The second step is a big one, though; I have to familiarize myself with the editor at a much deeper level, so I even have a clue what I’m looking at in there.

It’s sort of a lot.

For the type of recirculator, it will be in this configuration reply. ch16, cc 62, bits in the mask 0x07 values 0=Reverb, 1=mod delay, 2=swept echo, 3=analog echo, 4=Digital echo LPF, 5=digital echo HPF
bit 0x40 signals Extended recirculator time (1/2 sample rate).

This is very helpful. I can store a list of the FX labels associated with each of those.

If you send the ch16 cc109 value 32, you get the list of preset names and their category codes back. This will be ch16, cc56 value 0 for the name and value 1 for the control text that encodes the categories. The cc56 is followed by a series of ch16 Channel Pressure messages where each value is one character of the text, followed by ch16, cc56, value 127 to terminate the data stream.

ch16 cc109, value 16 will return the current configuration – all the usual global settings, and also the MIDI defining everything in the Eagan Matrix on channel 15 (I think – you might need to pretend to be the Haken Editor by sending it ch16 cc 116 (any) to receive the matrix data). None of the Eagan Matrix MIDI is documented.

This, I was able to extract most of from the Continuum manual, with a bit of trial and error. Mostly error, it seems.

The patch names, for instance, don’t come from that at all - my signals are on CC 32 for some reason, with different numbers indicating which bank that name is associated with, or something.

I’ll have to restructure around your notes and see if things are more clear.

(I am thus far only able to grab info for the currently loaded preset. Whereas, I should have like a list of 16 names, I think. Still working out that part.)

CC87 handling: Eagan Matrix sends cc87, followed by the Midi for whatever signal it’s the least significant bits (LSB) for, whether that’s pressure, bend, or something else. Always the same order. So, when you get a cc87, save the value, and when you get a message that uses the extended precision, use the cc87 value and reset it to 0.

Exactly. And once this order of messages is understood, you can also manually read the output from a MIDI monitor/MIDI logger in order to study what is actually being sent by Osmose. Thats what I did months ago, and I’m yet to see a CC87 that was actually paired with a pitch bend message. Even when I tried to explicitly set X to MPE+ in the EaganMatrix editor, as far as I remember.
