Extremely powerful

This is a very powerful MIDI control app. I have a number of MIDI utility apps and it can do things the others cannot with ease and even includes graphical feedback in realtime. The support and engagement from the developer is top notch. It does require a decent understanding of MIDI features and parameters for setting thresholds, triggers, and modifying note values, cc values and so forth.

Its been really interesting to use, and the manual and help information is quite extensive. Highly recommended.
