Voice Editor

Edit every voice parameter on your DSI Tetra in real-time. Adjust and fine-tune the oscillators, filter, envelopes, LFOs, and modulation capabilities that the Tetra offers:

Visualize and edit all of the hundreds of parameters in a Tetra voice
Quick editing of all sequencer tracks, with randomization and copy/paste functionality
Copy/paste envelopes for ease of editing
Copy/paste/initialize/randomize all of Layer A or B

Combo Editor

All of the features in the Voice editor are also available for editing Combos. Easily visualize all 4 parts of a Combo, and edit any parameter.

Parts of a Combo (layers) can be copy and pasted, as well as loaded from your Tetra Voice library. Individual parts can also be saved out as new Voice patches. Pull interesting voices out of Combo presets, and build new Combos from parts of old ones.

Bank Editors

Edit and organize all of the Tetra's 512 stored Voices and 128 stored Combos. Patch Base gives you direct access to all banks, so you can organize them and back them up to files on your device.

Patch Librarian

Save patches and banks as files

Patch Base saves files as sysex that can be sent to your synth by Patch Base or any general-purpose sysex transfer app.

Organize your sounds

Create folders to organize your patches and banks on iPad or Mac.

iCloud integration

Optionally use iCloud to make your patch files accessible on any iCloud-connected device, and to sync between Patch Base on Mac and iPad.

Import sysex files

Import existing patch and bank sysex files. On Mac, drop your files into the browser. On iPad, import using iCloud or the Files app.
