iDP/4 is a MIDI editor for the Ensoniq DP/4 effects processor.
The app itself doesn't make any sound but controls the parameters of the hardware unit.

You are able to control the followings:
- 43 effect algorithms and their individual settings
- Effect routing between the processing blocks
- Load any of the factory presets
- Save the current presets to local storage
- Access the saved presets in the iOS Files app

IMPORTANT NOTE: you should upgrade your unit to the latest firmware (1.15) for the best experience.

The app is free to try and to make sure your MIDI setup is working correctly. An in-app purchase is provided to access the full functionality.
