The monotron delay is an analog synthesizer optimized for sound effects. In addition to its analog oscillator, filter, and LFO, it also provides a space delay that's indispensable for swooping, cosmic sounds. The monotron delay even reproduces the pitch changes that occur when you vary The delay time, just as though you were using an analog tape echo.
