This is the live performance patch for my solo guitar and electronics piece, Roses Don't Need Perfume. It's a simple example of a user interface and had to be fool-proof so that the guitarist, Ken Meyer, could run it on his own system, edit it as needed for a particular performance. The patch utilizes my sfplayer abstraction, a reusable soundfile player object with a nice user interface. The patch is documented internally and may be used and modified under the GPL (GNU Public License).
