Hello there, thanks for your support.
The midi gear is a Muse Receptor. Since I'm a Linux admin since 1995, I customized the inner workings of the software by adding a RTP-MIDI implementation directly inside it, so the MiDI Designer can connect to it via a wireless network. The receptor works with presets, (program changes), and each preset has one ore more vst instrument.
What i'm currently doing with S1 Midi Trigger (but I'd prefer the UI of MIDI Designer) is that I prepared a list of "scenes" for each preset: A scene, for example, lets me raise the volume of an orchestra and a choi for scene 1, then for scene 2 get those to 0, and raise a lead synth volume, and so on. This guarantees speed and performance in a live situation.
You'll understand that each "preset"/"song" got different scene layout and different commands that must be sent for each of the scenes available: so for instance, every preset must have its own layout. From here, the need to have a different layout for each preset.
Thanks!
