MIDI GUITAR Channel/String Router

Hello

Here is the hardware/setup

Epiphone SG electric guitar + GK3 hex

Axon AX100Mk2

RME Fireface UC (buffer 64 / Win 11 Pro)

Max 8.6.5 / Live 12.4b9

I receive 6 midi channels from the AXON, one per string.

I need to be able to route each string to different Live tracks and to change this routing on the fly while I am recording.

Since Live doesn't handle different midi channel per track. (a pity...)

I created one track per string, each one monitoring (IN) a channel/string

In each of those tracks there is a little device.

Here is the one of the 1st string

In another track I have another device that handle the routing with a Matrixctrl object (C1, C2, C3 etc... are the data per strings). In the matrixctrl object, the six 1st rows are my 6 strings (the 7th one is for a keyboard) and the column are my Live tracks (seven differents tracks here).

In the example below, the 1st string does nothing, the 2nd one is sending datas to the 4th Track named 'D', The 3rd string is sending to the 2nd and 4th tracks (M and D), etc.. :

In Live I created tracks V, M, Oc, D, S, B, H and in each one there is a receiving device. Here is an example of the device in the 'M' track at the beginning of the devices chain:

But I want to be able to record the incoming notes per track in session and/or arangement.

Because the notes are sent via Send/Receive objects. The Live tracks cannot record them directly, the notes arrives 'after' the track input..

So I had to create another bunch of tracks with the input put to the output of the tracks where the above devices are.

So I can record the notes in this tracks. It's, finally!, in this track that the softsynth are..

You can imagine that the latency is quite important.

for example. If I monitor the audio output of the guitar and the output of an hardware synth, I can see that for the lowest E string (the synth has no Attack time) is 44ms and 13ms on the highest note of the high E string..

Sorry for the long post..

Since the only goal is to have a router per string for differents Live tracks and I want the lowest latency as possible. Is there another midi guitar player that can advice me ? (I know that Source Audio, you can be my helper =)

For information in the Axon editor, the sensitivity is at the highest possible and the tracking is good without double trigger. The GK3 is setup to have the less possible space between the captor and the strings before the string is touched when I play...

Another thing is that I tried to measure the latency directly in max, in the example below the "2" input is my guitar directly plugged in the 2nd input of my soundcard. And the "3rd input" is the direct output of an hardware synth (moog minitaur here).

I really neeever use audio [xxxxx~] objects in max and work only with midi/data objects, so maybe the patch below is very wrong....

I tried to measure the latency with the patch below.

The results you can see in the console is 5.21ms for the lowest E string and less than 1ms for the highest possible note. But I would be surprise if those results were true since the measure I made in the waveform jpg above (44ms / 13ms) are very different.

But when I play only in max, I "feel" that the latency is better.

So.. Is there any advice the accomplish that :

recording notes per tracks in Live with an "on the fly" string router ?

PS : I tried using imp.midi but on window it didn't seem to work without a lot of stuck notes when you play fast. but i am open to this solution if therea re workaround...

EDIT : another strange thing. I f I monitor in a DAW the latency between the audio guitar input and the sound of the "in-built" AXON sounds, it's soo quick compared to the latency measured with the "midi out" port of the Axon...It's frustrating

Thank you !

Cheers.
