Steve Hawker wrote in to tell me about how much he's been inspired by Rheyne's videos here. He got himself Lemur and made his own layout (download links below), then got to making some amazing music on his classic Steinway!
1904 Steinway meets 2012 drum n bass. With the help of Ableton Live, Lemur on iPad, and a Wiimote it might just be possible. Live looping and sound effects are controlled with Lemur on the iPad, and drum loops are triggered with a Wii remote.
You can download the Ableton Live set (Live 8 needed), Lemur file, and OSCulator patch below if you'd like to have a play or use it as a starting point for your own live-looping experiments. If you're on a PC, you can use GlovePie instead of OSCulator to get the Wiimote to trigger drum loops.
[Right-click and "Save As..." on these!]
I also used the excellent free Aurex MFX1 effects rack which you'll need to download to use in the Live set. Details and link to download are here: https://www.ableton.com/en/blog/2012/06/14/mfx1-master-effects-racks-aurex/
