Tiptop Audio QuantiZer
Precision CV-to-musical-note converter with live performance controls
10 HP Eurorack module
The QuantiZer is a digital processor with high precision analog CV circuitry that converts incoming CV signals from sequencers, LFOs, envelopes, or any CV source into quantized western chromatic scale notes in under half a millisecond. It offers deep musical control including scale selection and editing, transposition, portamento, CV recording, and SyncBus integration, making it a creative performance tool for shaping and transforming melodies in real time.
