The Hel module is an expander for polyphonic oscillator modules from Xaoc Devices. It features five inputs, scaled in V/oct and each of them offers an independent control over a single voice.
The oscillator still offers its global V/oct input.
The actual number of voices depends on the capabilities of the oscillator. For example, Odessa offers 1, 3 or 5 voices.
The inputs of Hel are quantized in a chromatic scale.
Please note that the Spread controls in some modules (eg. Odessa) determine the degree of symmetric detune of the unison voices when Hel is not used, but they are still operational with Hel installed. Turning the spread knob does not affect the central voice which corresponds to the root input in Hel. Detuning affetcs voices 2 and 4 which are shifted downwards as well as 3 and 5 which are shifted upwards.
