Hardware synths that take MPE seriously are still a small club, so when one of them gets a practical software upgrade, it is worth a closer look. This week Waldorf released Chutney, a free preset librarian for the Protein, its compact wavetable synthesizer built around the legendary Microwave 1 oscillators. As reported by Synth Anatomy, the tool is available for macOS and Windows and talks to the synth over USB MIDI.

What Chutney actually does

Chutney lets you browse all 360 preset slots on the Protein and move sounds between your computer and the hardware by drag and drop. You can rename, reorganize, delete, restore and back up patches, which is exactly the housekeeping that makes a hardware synth feel less fragile. It is important to be clear about the limits: for now it is a librarian, not an editor. You will still shape sounds on the instrument itself.

That may sound modest, but anyone who has lost a favorite patch to an accidental overwrite will appreciate a proper backup workflow. For MPE players the stakes are a little higher. Expressive patches are tuned to a particular controller's feel, and a patch that responds beautifully to pressure and slide is not something you want to rebuild from memory.

Why Protein matters to MPE players

The Protein offers 8 voices shared across four layers, each layer with two wavetable oscillators. Layers can be configured for round-robin behavior or for MIDI-channel splits. Its 8-slot modulation matrix can respond to mod wheel, velocity, polyphonic aftertouch and MPE, and Waldorf describes the instrument as fully MPE compatible.

Those pieces fit together in useful ways. MPE gives every note its own MIDI channel, so pitch bend, pressure and slide can be applied per finger. A modulation matrix that listens to that data means you can map pressure to wavetable position, or slide to filter movement, and hear each note evolve independently. With eight voices you are not building huge orchestral stacks, but you can play expressive chords, drones and layered leads with real nuance.

The MIDI-channel split option is also interesting. In an MPE context you generally want the controller to send on a range of channels, so it is worth checking how the layer configuration interacts with your controller's MPE zone before you build a performance patch. A few minutes of testing here will save frustration on stage.

Practical details

According to the same report, the Protein supports MIDI CC for all parameters and SysEx for patch import and export. Firmware 1.0.2 added MIDI bank select (LSB/CC32) across all 360 memory slots, which makes it easier to call up sounds from a DAW or controller. MIDI in and out use mini TRS Type A sockets, with adapters included in the box.

Pricing has moved since launch. The introductory price of 329 euros has ended and the list price is higher, with the US price at 499 dollars, so check Waldorf's site for current figures and availability, as units have been in short supply at times. The Chutney librarian itself is free and lives on Waldorf's Chutney page.

Tips for getting started

The bigger picture

Small software releases like Chutney rarely make headlines, but they signal something healthy: manufacturers are treating expressive hardware as instruments people will live with for years, not novelties. A compact wavetable synth that understands MPE, backed by a free librarian, is a sensible option for players who want expressive control without building a computer-based rig. If an editor follows, the Protein could become an even more attractive companion for MPE controllers.
