This module was originally designed to enhance the Slew Processor module by making it easier to use Slew Processing on audio signals. The module takes a 1V/Octave CV input (which defaults to the Pitch input from the Voltage Modular IO panel) and converts this to a CV representing the time period of a waveform at that frequency.
The calculated time then has a global Octave and Semitone offsets, settings for full cycle, half-cycle or quarter-cycle timing and scaling of the output signal to 10ms/V, 100ms/V or 1 second/V. In addition to a simple output, two additional processors allow this amount to be attenuated and to have a modulation CV source mixed in so that you can easily control the Up and Down channels of the Slew Processor for used with audio signals.
The module can also be used for other scenarios, such as adjusting the envelope times in the Voltage-Controlled Envelope.
Also sold as part of Andrew Macaulay's Envelope & LFO and General Utility Collections and included in Andrew Macaulay's Ultimate Bundle.
