Ok folks it turns out that the TD-20 can put out 5 notes for all the HH articulations BUT it doesn’t do it as part of the factory default. And if you change it and record midi from the TD-20 and try and play back WITH the TD-20 it won’t give you any closed edge sounds. The TD-20 HH works best when receiving midi with just two notes.

Anyway to change this to work with external Romplers HH you have to go to Setup – Midi – HH Note # Border and change the value to something between 80-100 for it to put out separate open and closed notes for tip and edge. So now I was able to map the other two notes to the articulations and expected things to sound and work better. Still doesn’t sound or work well. The closed tip sounds VERY much like the edge on open and closed and there’s still errant open pedal sounds. And it’s nearly impossible too get a tight closed sound and dynamics even after adjusting the sensitivity for the HH pad.

Any other suggestions guys?

The rest of S2 is great and I’m loving it – just hope the HH gets more attention.
