Though the Tenori-On (hardware version) has been out for ages (since 2007-2008) there aren't many videos of it being used with a 200e Buchla.
Paul (Cobramatic) & I decided to trial the i-pad Tenori app and the hardware sequencer yesterday. Loved them both. Spoilt for choice.
The Tenori-On i-pad app
Both the app and hardware Tenoris are
unique ways to create music. There are 16 layers or for our purpose
there are 16 channels of midi. The first 7 are very much like your
standard midi sequencer.
Layers
8 to 11 use Random Modes. Layers 12 and 13 allow you to "draw"
sequences. Layers 14 and 15 are unusual : called "Bounce" and "Push"
Modes.
