Jason from iPadLoops did a great tutorial for Odessa... unfortunately the audio is a little wonky.
You're going to have to crank this way up to hear him, but it is worth doing so!
Here a neat trick when using Odessa Bassline in AUM. One finger wonder.
Odessa Bassline is an audio unit including in the Bram Bos Odessa midi suite. More info here http://ipadloops.com/odessa-acid-brea...
Also in the mix, iSEM synth with NoLimits compressor and Bismark BS16i sequenced with Odessa X0X ran through FoldR wave folder.
