Mark Mosher of Modulate This! put together this tutorial that demonstrates how you can add velocity to Tenori On notes, using Ableton Live.

By default, the Tenori On sends fixed velocity.

See Mosher’s site for more details.

In this YouTube Video, I demonstrate how to use Ableton Live 8 and the Velocity MIDI device along with a dummy clip to add velocity to incoming MIDI notes that are a fixed velocity. I illustrate this with the Tenori-On but this concept will work with any MIDI device.
