Qmidinet routing between 2 zynthians

[ToFF]

Hi @albyconcalma ,
let me point you in the right direction. You’ll probably handle the connection between the two Zynthians with QMidiNet, but I would actually use a simpler solution: a USB–DIN MIDI converter.

More important is that two MIDI LV2 plugins were created which allow you to route MIDI signals out of Zynthian:
you enable them from the zynconfig web interface under ENGINE → MIDI tools, and they are:

CC Send (created by @riban)
MIDI Control External (created by @jofemodo)

During the testing phase, riban summed up their behaviour here:

Send Midi CC+PrgCH?

Yep! That has fixed it. @jofemodo’s approach is very logical and with the right detailed knowledge of MIDI you can do what you need. There is no configuration required. There is a direct one-to-one mapping of everything with a hierarchical structure. I like the logic which is where I started but I broke from that for reasons of workflow. (This feels like a role reversal. It is usually @jofemodo who is guiding me away from logical implementation towards workflow driven implementation!) Observat…

For your use case, CC Send will probably be the better fit with ZS3 - Zynthian Sub-SnapShot.

Once you enable them, you can insert them into a chain in Zynthian via Add MIDI chain, then select category 5 – Other. Don’t forget to set MIDI Out in the Chain Options.

In general, any LV2 MIDI plugin should have its output routable to a chosen MIDI device, so you can (at least in theory) also use other plugins than the ones I pointed out.

EDIT: There is also an LV2 MIDI plugin called MIDI Thru – try whether the signal passes through it to the output you’ve selected.
