Description

Voltage to Language

The Grendel Formant Filter has three control voltage (CV) inputs: Size, Articulator X, and Articulator Y. These are optimized for 5 volt analog control signals, but can accept up to +/-10 volts.

The Size parameter moves all four BPFs in parallel. This affects the overall size of the filter’s ‘mouth’.

Articulators X and Y work together to select vowel tones from a two-dimensional map related to the IPA Vowel Chart. For optimum control, these inputs can be connected to an analog joystick controller or two channels of a MIDI-CV converter. The ideal voltage range for controlling Articulators X and Y is +/- 2.5 volts, or 0..+5 volts. See the Patching Guide for further detail.

Suggested signal sources for the CV inputs are LFO, envelope generator, MIDI-CV converter, analog joystick controller, etc…
