In addition to adding a Local On/ Off from the synth w/o the computer, it would also be very useful to have the fidelity to turn the keyboard off but still have local control of the front panel (similar to Voyager Local On/Off options). I run into this often where I'm using the Matrixbrute to control other modular instruments and want to use the Matrixbrute's onboard LFO's and envelopes routed outside to other modules. When Local Control is off the front panel does not respond to knob and fader changes. I've resorted to muting the VCOS, with Local On, so I can use the modulation features outside of the Matrixbrute.
Thanks
