Michael Eskin is going through his back catalog and doing demo videos for all of his old apps. This one for iJammer caught my attention. These hexagonal harmonic keyboards are pretty interesting, and this one does MIDI!
The demo is for version 2.0, and it was recently pulled from iTunes, so Michael is just teasing us until that comes out.
There is a special note for users of previous versions to check out the Migration Guide (PDF), before updating! The way it saves your page layouts has changed dramatically, but this should have an equally dramatic improvement on performance.
This update is so big that Intelligent Pad Touches was able to port their FL Studio Lemur template over to TB MIDI Stuff 2.0! The download is not yet available on their site, but there is a demo video of it in action.
