09The Schlappi Engineering Interstellar Radio is a faulty transmission line providing several varieties of destructive effects as well as acting as a non-volts/octave complex oscillator when no input is provided.
Interstellar radio converts an audio signal from the input jack to a high frequency pulse train and then back to an audio signal with voltage control over the clock for the up conversion (CARRIER) as well as the down conversion (DEMODULATOR), like a voltage controlled radio transceiver designed for poor reception.
Manipulating these clocks allows for a variety of aliasing, distortion, and frequency modulation type effects. The output is also sent to a comparator along with the input, and the result is available at the “ERROR” output for a ring modulation type effect. It can also create sounds reminiscent of PLL (Phase Locked Loop) & bitcrushing!
When no input is provided a DC offset (controllable with the input jack) sets a frequency for the up conversion (which is effectively a VCO), the down conversion acts as a modulation oscillator allowing for a fairly radical form of frequency modulation. Two audio signals can be inserted into the clock input jacks and modulate each other in the same way.
- Simulates the process of modulating and demodulating a signal for radio transmission
- Effect or complex oscillator (non v/oct)
- Voltage controlled aliasing, distortion, and frequency modulation effects
- Two wide ranging voltage controlled square wave oscillators with individual outputs
- CARRIER oscillator converts input into high frequency pulse train
- DEMODULATOR oscillator inside control loop brings sound back to audio range
- CV applies external voltage control to oscillators or uses input signal as audio rate FM
- Internal oscillators can be replaced with external modulation sources
- TYPE selects demodulation loop type (changes timbre and response)
- ERROR output with threshold control
- TONE control for filtering out the harshest of frequencies
- All analog design
