Sending "control all" messages to tweak the same parameter on a selected number of TG

[Onosendaifr]

When using Mini Dexed as a 8 parts multitimbral instrument, sometimes i need to build tension by increasing the same parameter on a selection of TG.

For exemple, increasing the reverb send to all the parts at the same time, but not the drum part.

Or playing with the filter Cutoff everywhere to do a DJ like transition.

To do so, 4 things are needed :

• A Mute/Active page to select wich part will receive those messages
• An assignable MIDI button that need to be keep pressed to send those messages
• A physical rotary encoder or a MIDI CC to tweak
• Another button to cancel everything and come back to the original Performance

Yes, i use Elektron machines :)
