RZ-12 Resonator manual
A color effect that makes any sound ring on the notes of your key, with an octave shimmer over it. RZ-12 Resonator adds the color of a key to whatever goes through it. Glow puts a resonator on each note of the key, so a plain bass turns into color bass, a flat pad or lead glows, a drum loop rings in tune and noise turns into chords, and Shine lifts an octave shimmer over it. Under the ring, every part of the sound that sits between the key’s notes moves onto the nearest one, so all that rings stays in key. A three-stage drive comes first, giving the key’s notes more to ring on, and a reverb and a limiter come last.

The four knobs
The four knobs on RZ-12 Resonator’s screen shape the whole sound, and each preset sets where they start.
- Glow
- From the sound as it is to the key’s notes ringing loudest through it.
- Grit
- Drives the sound before it rings, from clean to all driven, so the key’s notes have more to ring on.
- Shine
- Carries the glow into the top and lifts an octave shimmer over it.
- Space
- Opens a room around it, from dry to a long, wide space, with the sub kept dry.
Your DAW records every turn as automation, and Undo takes a turn back.

Any key in nineteen scales, or your own notes pressed on its keys, or Follow Notes to ring on the notes a MIDI track sends it. About 2 milliseconds of delay, which your music app makes up for, so it can sit on a track you record through. On every bass preset the sub stays centered.
- Multi-Stage Drive
- Stacks three distortions, each on its own band, such as saturated lows, clipped mids and crushed highs with the rest left clean.
- Key Snap
- Moves every part of a sound that sits on an out-of-key semitone to the nearest note of the key, and turned further rings the key’s notes through it.
- Shimmer Reverb
- Adds a reverb whose tail climbs an octave or a fifth at a time or sinks, and can freeze into a pad.
- Clip Limiter
- Sits last in the chain, a clipper into a limiter that holds the output under the ceiling you set.
