FM Voice Editor

You don't have to be a wizard to program FM sounds. You just need good controls. Patch Base makes FM easy to work with by showing you the layout of the currently selected algorithm and the envelopes and settings of each operator. You can finally visualize what's going on inside of the Volca FM2, and once you do, it's not that complicated.

See the layout of the current FM algorithm, with the envelope shapes and ratio settings of each operator
Copy/paste the settings for entire operators
Copy/paste envelopes for quick editing
Easily edit the pitch envelope and LFO settings

Sequence Editor

Unlike the original Volca FM, the FM2 offers full access to all the data of an internal sequence. You can record a sequence on the Volca itself, then import the sequence into Patch Base for fine-tune editing. Or, create a sequence from scratch in Patch Base by hand, or start out with a random sequence. Create automation that you could never pull off by twisting knobs.

Edit all individual note, velocity, and gate information
Graphically edit Motion data using several different tools
Adjust the timing, effects, arpeggiator, and more

Bank Editors

Patch Base's Bank Editors let you change and organize the saved sounds on your Volca FM2. Load, fetch, and save, banks of 64 Voices and 16 Sequences. Save them to files for later use. Mix and match.

Backup

The Backup section gives you 1-click fetching of all the Voice and Sequence data from the Volca FM2, which you can save in a single file for later use, or sharing.

Full Sequences

You can also save Sequences as “Full Sequences”, which will include both sequence and voice data in a single file, so you can save a load a Sequence along with its related Patch without worrrying about what's stored on the Volca itself.

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.
