After working a bit  more with this unit, One thing I would like to change…make the source choice with the option to save per preset, not just global. I use the H90 primarily with bass. When using the synth algos, some sound and track better on lead, some bass ,some sub. It would be so much more convenient to store them with the program or better yet set a note range for the source ( source audio does this with the C4) (Panda midi Future Impact sets an input source and octave range up to 4 octaves). A couple of examples of how to do it different.

It would be nice to have at least a basic bass and treble EQ in all algos too ( possibly in addition to a global EQ?)

Key tracking on the filters for synth algos would be nice too.
