The Seaboard is a good MPE-controller. No doubt.
But - I recon it would have even better if - one could switch off certain messages. Thing is - it is also a great addition to other instruments.. I.e. using the Rise as a ribbon-controller when you're actually playing another synth. Or modulator - or whatever.. SO - the ability to turn off control-parameters, is - for this kinda use - just as important as having them available. It would just add to the usability of the thingy.
I have digged into the system (Dashboard) and I cannot find this. I recon it would be one of the easiest firmware-updates to perform.
