I'm digging deeper into BEAP. Note - I've created a category for BEAP posts - http://www.modulatethis.com/beap/.
Today I worked out how to use a BEAP patch with Max for Live. The trick is to MIDI from Live's "midin" object to BEAP's MIDI to Signal then map the audio to BEAP's M4L-OUT. You can then use your controller to send MIDI notes to beap, rack up the patch, assign Macro's, use Live devices in the device chain.
To test all this, I map various knobs to macros from within the patch plus route MIDI CC 30 to change the speed of the LFO. I've also mapped the delay time to a macro with the delay set to "repitch".
