Wolfs MIDI Tool Box has some cool stuff.
The Panic Button is really nifty becasue it sends out 128 note off messages on whatever channel that's selected.
I have never really needed it but recently became very mobile, so I needed to replace my hardware PatchBay and MIDI Solutions F8.
Modular has oblidged.
Just put the Panic Button before the Modualr Patch, and attach a MIDI CC to the reset button.
Any selection of channels can be used thanks to Alfonsos MIDI Router.
I slam a slider and send note offs to all channels.
Also have replaced my 1U MIDI Soultion F8 with tgstgs's MIDI Generator. ANy message can be sent including SysEx strings.
