Take a look at Alsa Modular Synth too...I tested most of the available
apps out when I started doing this. Ecamegapedal was a bit glitchy at
least on my box. (A couple or 3 releases ago) Alsa Modular synth had the
midi support you need built right in and the "parameter" settings are
awesome for filling the midi gaps. ( I had limited controller options
and ended up using Prog Ch. for toggling fx. AMS is realtime and has an
array of useful stuff.
