the ooh-wah is sort of a combination of a tremolo and a wah wah pedal

This can be useful to create a slow attack effect

as well as Pulse Width

This allows the synthesizer to be controlled by a midi keyboard

A portable synthesizer delivering maximum flexibility in an ultra-compact body

Tiptop Audio VCA Voltage Controlled Amplifier Utilities_Inverters the ooh-wah is sort ofThe Tiptop Audio VCA is a full featured, precision calibrated, analog Voltage Controlled Amplifier. At its heart is a novel design of a control circuitrya function that lets you sweep continuously through three different response curves: Logarithmic, Linear, Exponentialgiving you all three shapes in a single module. This special control circuitry design by Mr. Osamu Hoshuyama was adopted into the VCA module to make it a great sounding synthesizer VCA
