Catalinbread Heliotrope Harmonic Pixelator
The Heliotrope is an "analog bit crusher" of sorts. Since there is no analog to digital conversion happening it isn't a true bit crusher, hence the name "Harmonic Pixelator".
It works with guitar, bass, keyboards, etc. We designed the pedal to be intuitive and easy to use even though what it is capable of sonically is actually quite complex and varied. The Heliotrope can be powered from a 9v-18v adapter or a 9v battery. At 18v you’ll notice more output volume and headroom is available. Your instrument of choice (aka: Program Frequency) feeds the Heliotrope an input signal. From it is subtracted the Carrier Frequency. The Carrier Frequency is set by the Hi/Lo switch and the Sample Rate knob. These are the rough ranges of the frequencies governed by the Hi/Lo switch: Hi: 1.44kHz - 6.66kHz / Lo: 333Hz - 1.58kHz So if the Carrier Frequency is tuned using the Hi/Lo switch and the Sample Rate knob to around 440Hz and you play a high E string at around 320Hz the output is roughly 110Hz or an A String. With a little thinking you can break down all these intervals and harmonize with the pedal - or you can just have fun and set it to an interesting resonant sound and see where it takes you. Enough math – let’s rock this thing!
