Here is an example exploiting the CV input with the CV Sequencer…
This is a maximal drone synthesizer capable of dense sounds and thick chords. Six oscillators modulate against each other. Each selectable as either full range, off, or low range. There is also a low pass filter and volume. A CV input allows you to power the device with control voltages from 0-5V for interesting automated power sag results.
The case is extremely tough die-cast aluminum painted with a durable textured black finish. The CV input is 1/8″, and the mono 1/4″ audio output makes it easy to connect to amps, effects or recording equipment. It is powered by an included internal 9-volt battery or any 9V center-negative DC adapter. Connecting a power supply will automatically disconnect and reserve the battery. This was designed and hand-built in Oakland, California.
