Akai MPC

The MPC app uses VST plugins by default, but AU plugins (on the Mac) can be selected in the MPC's PREFERENCES window. 

1. Select a track in the MPC Inspector window. In the MPC TRACK section, change the TYPE from "Drum" to "Plugin."

2. Select the Plugin menu and the plugin window will pop up. Open the VST tree and choose your Spectrasonics instrument.  Then press the Select button.

3. The Plugin will now be named after the chosen instrument and the default MIDI channel is set to 1. Click the icon next to the Plugin name to open your instrument’s interface.

4. The instrument interface will appear and you will be ready to record.
