I spent a little time yesterday experimenting with modulated loop selection in Emulator X on a variety of sounds.  One sound set that I particularly enjoyed playing was a set of blues harmonica samples at freesound created by TexasMusicForge.  For those who are not familiar with the freesound project, it is a great collection of user-submitted samples licensed via the Creative Commons.  Anyhow, I created a new EX instrument based on these samples and added multiple loops to a couple of them (actually up to 60 loops in one of the samples!), modulated with random LFOs.  The result was quite playable – you can hear an example on the podcast.  I would ultimately like to create a full composition with this instrument by refining this improvisation and combining it with other elements.  It's not a sound I have used very much in the past, so I'm interested to see what I can do with it.
