This second-generation 9700-series processing element for modular sound synthesizers is designed to provide great sound and excellent value. This module is designed to be compatible with most modular synthesizer systems with little or no modification. Most active components are already mounted, making assembly a snap.

This module provides two independent functions, a linear-to-exponential control voltage (CV) converter and a signal inverter. The linear-to-exponential converter can be used to tailor a linear control signal for input to a synthesizer module with an exponential control voltage response. This can be desirable in volume- and frequency- control patches such as using a CV scaled at volts-per-Hertz (V/Hz) as a VCF control input to track a V/Oct Pitch CV, or, shaping an Envelope or LFO control to a VCA, with the converter patched through the inverter. The inverter (with gain) may be used independently as a handy tool for inverting envelopes or obtaining complementary or mirror-imaged signals (one VCA LFO CV rises as the other falls).
