Here's my Ableton configuration.
Pedals 1-5 control the clips.
Pedals 6-8 control the Transport.
My APC mini reflects the FCB commands.
MIDIOX can be confused by having certain devices combined with certain others, usually if they're daisy chained. My eDrums will do this.
Here's the MIDI Monitor Plugin I use, eliminates the need for MIDIOX and that way too simplistic web app.
