I first tried to keep reasonable the number of matrix destinations.
The number of sound when you need to modify independentaly each of the 6 mixes through the matrix must not been huge.
IM5 could be usefull though.
I can understand that, though generally (at least for me), the more matrix destinations/sources the better! You could always use the modifier (x10) key to go faster through all the options if you needed.
And yeah, messing with each mix individually isn't too pressing, but I've been experimenting with using PreenFM as a very basic additive synth, with each of the 6 carriers producing a different harmonic, but I am unable to change the volume of the later carriers due to this.
