iPad Screenshots

The E-mu Proteus/2 is a rompler/synth first released in 1989. Each voice consists of two "instruments" (samples) that can each be detuned and enveloped independently, along with a wide range of modulation capabilities. Presets can be linked to make larger sounds, and the built-in chorus gives additional width and depth to your voices. The Proteus also allows full microtuning of every key independently, for the adventurous. Patch Base gives you easy editing of every preset parameter as well as control over all the other controls of the Proteus, and includes a Bank Editor to back up and organize your sounds.

Preset (Voice) Editor

Patch Base gives you quick, direct access to all of the parameters for the Proteus/2 on one screen:

Edit both instruments, all of the real-time modulations, key/velocity routings, LFOs, and Chorus in real-time
Copy and paste envelopes for easy editing
Get a bird's-eye view of the whole structure of a Proteus preset
Save Preset, Tuning, and Program Map data to files on your iPad or Mac

Bank Editor

Edit and organize the 64 Presets stored in your Proteus' User memory. Patch Base gives you direct access to the bank, so you can organize patches and back them up to files on your device.

Patch Librarian
