Pisound – Switching Graph and Presets via Different MIDI Channels Not Working Together

Hi everyone,

I'm using a Pisound and I'm trying to switch both a graph (patch) and a preset using MIDI, but I'm having trouble getting both to work together.

  • MIDI Channel 1 is used to switch the graph.

  • MIDI Channel 2 is used to switch the preset.

The issue is: when I send both MIDI messages (for graph and preset) at the same time, the preset switch doesn't work properly. It seems like the preset change is being ignored or doesn't apply correctly—maybe because the graph is still loading.

This is important because I'm building a multi-effect device, and I want to be able to switch between different effects and their corresponding presets using a MIDI foot controller. For switching between different effects, using graphs works best for me.

Has anyone experienced something similar? Is there a way to make sure both actions work reliably when using different MIDI channels?

Thanks!
