Thank you for your answer.
In fact, it is already possible as you described, although I don’t understand what you mean by “So consider “Layer Group Presets” to be just Parts and off you go, no?”
The “problem” is that graphically you cannot immediately understand which and how many layers are generating a sound compared to other layers that generate another.
Example: my synth consists of:
Layer 1: vst instrument x
Layer 2: External expander ch1
Layer 3: External expander ch2
Layer 4: External expander ch3
Layer 5: External Expander 2 ch1
Layer 6: External expander 2 ch2
In total I have 6 layers for one sound.
I would like these 6 layers to be closed in a “folder” that would make me immediately understand that they are different layers, but that they contribute to the same sound.
You understand that in each part I have an average of 6/7 sounds, each of which is made up of 4/8 layers… it’s not easy to understand which layer does what.
If it were possible to assign a keymap to each folder dedicated to a sound, it would be fantastic!
I hope I was clear, and thanks for your support
