Dave Smith Instruments Tetra Editor and Librarian

Patch Base has the best Dave Smith Instruments Tetra editor and librarian available for Mac and iPad. Edit any parameter, organize patches, create random patches, and more.

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.
