Chorus scene selected

Recall the next scene on cue.

Save plug-in settings, rack levels, mute and bypass in scenes. Recall them from the keyboard or over MIDI, with a fade time you choose. Keep routing, meters and rack controls in view as you work.

Choose your devices. Set your buffer.

Select your input and output devices independently. Run at 48 kHz with a choice of four buffer sizes.

Give each rack its own output.

Route a mono or stereo input through your plug-in chain, then send its stereo output directly to your audio interface. Each rack routes to its output pair without a shared master bus.

Superposition routing controls for the Keys rack, with input 2 and stereo outputs 3–4 selected.

Keep a crash in its rack.

Each rack runs in its own process, separate from the audio engine. Plug-ins within a rack share that process. If a plug-in crashes, the whole rack attempts to recover while the other racks keep playing. If recovery fails, the affected rack passes unprocessed audio.

Signal path: device inputs, the audio engine, four racks each in its own worker process, then output pairs to the device.
