Key Features
The Analogue Systems RS-375 Harmonic Generator Expander is an expander module for the Analogue Systems RS-370 Polyphonic Harmonic Generator Module. The RS-375 adds a range of functionalities including 16 control knobs, 20 CV inputs and 4 outputs to the RS-370 (labelled CTRL 5 - CTRL 8) that expand the capabilities of the RS-370. One of the main features with the expander is that it offers you a quick and direct way to control the onboard envelopes. The RS-375 is essential for real time harmonic synthesis with the RS-370. When the RS-370 is in its real-time modes the module essentially becomes a monophonic synth. You can then use the knobs on the expander and assign them to set the levels of the first 16 harmonics. The RS-375 Harmonic Generator Expander and RS-370 are perfect companions for harmonic synthesis and a must have when generating real time additive synthesis in single voice mode.

The 16 knobs and CV inputs are controlled in menu 2.5 of the RS-370 Polyphonic Harmonic Generator Module. The knobs and inputs are arranged in pairs. The controls can become very flexible. When the menu is set to 'Envelope Generator' you can set up the each stage of the EG with the first 10 knobs and control modulation. The 16 knobs and their associated CV inputs can control 2 sets of parameters. The first is the ability to control the ten contour shape parameters in the envelope generator which can be modulated by applying CVs to the CV inputs. The second gives you the ability to control the first 16 harmonics and adjust these individually with the option to also modulate the same way by applying CVs to the ten associated CV inputs.
The RS-375 is ideal for real-time harmonic synthesis. When the RS-370 is in its real-time modes it then becomes a mono synth and then the knobs on the expander can be assigned to set the levels of the first 16 harmonics. Experiment with varying harmonic content and transform the generated waveform dynamically, something not possible with the RS-370 alone.
