Synthesizers.com - Q142 Pedal Interface
The Q142 pedal interface offers a way for foot pedals (actually any switch or potentiometer) to control your synthesizer.
Each of the two independent sections allow simple switch pedals or variable pedals to create control voltages that can be used to control virtually any module in the system.
Control volume, filter sweep, pitch bend, pan/fade, and more. Various voltage levels and polarities are produced for each pedal.
Seller Notes: Multiple used copies on hand, images are of an example of stock. All items are in good quality but some scuffs to the metal may exist. As well component chips may very but function is exactly the same.
There are 2 independent sections to the Q142 pedal interface.
Many switch pedals have an option for normally closed or normally open operation. This is not very important because the Q142 can offer both polarity of output voltages at the same time. Use the 0/+5 outputs to start/stop the Q119 sequencer, envelope generators, or to control a slew limiter or switch modules. The +5 output can also be used to turn on an amplifier or select a Pan/Fade condition.
Variable pedals provide continuous control of a parameter. Normally this will be the -5/+5 output, then attenuate the signal on the module. If the module doesn't have an attenuator, use the Q125 Signal Processor. Variable pedals are great for controlling filter frequency and resonance. You can also control an amplifier to mix in another patch or a Pan/Fade module to switch between voices. Variable pedals can also be used to trigger modules. Most modules that accept a gate signal will trigger at 1.5 volts.
