MIDI note allocation, is it possible to reassign?

Hi all,

I’ve really valued this forum as I’ve learnt the OT and have been able to overcome all the issues I’ve faced so far - apart from this one…

I have a midi pedal (disaster area DMC-8 Gen3) - which although excellent in other regards, unfortunately doesn’t allow for assigning of midi notes. There is a mode on it called access mode which on channel 16, will send MIDI Notes 1-11.

I would like to use this pedal to utilise the OT looper and playback start/stop. Obviously the OT note allocation is already defined (start/reset=note 35. Start/record = note 60 etc etc) - what I wondered was if there was a way of reassigning these midi notes to correspond with the ones that the DMC-8 Gen3 pedal can map to?

Appreciative of any help.

Yes, with a midi processor like Event Processor Plus.

Or in hardware, you could easily do that (and much, much more, of course) with an Axoloti.

That’s helpful thanks. Are there any other midi event processor / translator recommendations - seems like a lot of cash to splash.

Raspberry Pi + cheap usb to midi cable?

Arduino + midi shield too.
I also have an Mep4, cheap, but huge.

Remember with the Axoloti you’re more or less getting a next-generation Nord Micromodular without the case, screen or knobs. I’ve had one for a few years and it’s pretty impressive, although I don’t use it nearly enough these days.

So in that sense it’s a really good deal. For only processing MIDI events it’s kind of overkill though.

Seems very interesting. Do you know if you can split midi channels per note as Midipal/Midibro/Rk-002

It’s a full-blown, Puredata style modular programming environment, that would be no problem.

Recent versions of the firmware include ports of all the Mutable algorithms, among other things.

Last thing I did on it was a pretty deep Karplus-Strong implementation with three resonators in parallel CC control of every parameter of the algorithm, including an ADSR envelope for the impulse. It barely scratched the surface of the possibilities of the Axoloti (although it did use up about 30% of its CPU).

This is my favorite Axoloti demo so far, an entire live rig made using only 5 Axoloti boards with custom hardware interfaces:

I made an axoloti program to go from a midi keyboard to drive individual channels of Nord drum, ie, a midi dispatcher. You could conveivably do anything you can imagine if you’re use willing to code it.

Is the ks synth available? I’d love to try it :slight_smile:

I have it someplace but it was written on such an early version of the firmware that it doesn’t work anymore.

I’ll see if I can find it. It’ snot a masterpiece or anything, it was very much a work in progress still when I sold the Beatstep Pro I’d been using the Axoloti with and kind of shelved it for a while.

I’ll see if I can find it and upload it, maybe you could at least get it to open up and port it to the current version.

Here it is.

EDIT: Just to reiterate, this WILL NOT RUN on the latest firmware. I was running a version from late 2015 when I made it.

One version has CC assignments for a Beatstep Pro, the other doesn’t. I can’t remember if here were any other differences. It looks like it was last edited in the middle of September, 2015, so if you can’t get it running on a newer version and really want to, you could install the Axoloti firmware that was current back then but I wouldn’t go that far if I were you.

It’s really geared toward making atonal, metallic sounds, don’t expect to be playing melodies with it as it is here.

If you make any modifications PM me a link or post it here, I’d be interested in trying what you come up with.

I’d like to see your midi splitter code and patch , to be sure if I can modify it without headaches.
Thanks.

I will see if I can find it, it was in my old OS X install before I put a fresh one but it shOuld be in my time machine backup. If I don’t get back to you in a few days please send me a msg.
