Low epic throbbing halls, rasping vocal choruses, burning thick churning waves of static. The Yowler is waiting. 

The Yowler is a versatile little noise/drone synth, don't let it's size fool you, it is packed with features most small synths don't have:

External trigger + decay: trigger the Yowler from external gear, use it as a drum synth

Built in speaker + mono/stereo output: means you can use it with mono gear like guitar pedals or a modular synth, or stereo gear like mixers, headphones etc...

Pitch knobs + light dependent pitch control: get crazy sounds from the three oscillators by shining light on them

At its heart the Yowler is three square wave oscillators with pitch control that goes from very low to uncomfortably high. The pitch is controlled by knobs with switchable light dependent resistors. The oscillator mixing happens through two XOR gates creating rich harmonics, screaming highs and throbbing lows. The third oscillator can be switched off. A diode VCA (voltage controlled amplifier) can be switched on to allow external triggering of the synth, turning its voice off and on. The diode VCA can also be controlled with CV (control voltage) to create primitive volume changes. A switchable decay capacitor creates drum sounds. The Yowler can be battery powered or powered from a DC wall wart and it has an independant volume control knob.
