Catalinbread Heliotrope Harmonic Pixelator Effect Demo
(At the 6:14 minute mark is one of my favorite settings)
There are a lot of weird noises I made with this pedal, so please do give the whole demo at least one full view
The beauty lies in the oddness of this pedal. I recently heard that Catalinbread is thinking of phasing this pedal out, but I just don’t think it ever got the love it deserves. There are a TON of odd little noises this thing can make, you really just have to play around with it. It’s part bit crusher, part Harmonizer, part Octave, and part Ring Mod…. all with a little fuzz thrown in there. You can dial in the fuzz with the gain knob…. but don’t expect this to have your run of the mill fuzz tones. If you really are looking for something to set your tone apart from others, this may be one to add to your arsenal….. especially if you are an ambient noise kind of guitarist or if you happen to score sci-fi movies in your spare time And yes, the song in the beginning is from on of my favorite sci-fi movies, Sunshine, by Danny Boyle…. well, maybe the first two thirds, the latter portion of the movie kind of jumped the shark. Anywho, if you enjoy this pedal, you may want to grab one while they are still available.

Here is the info from the Catalinbread website…..
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.
The controls work like this:
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.
The Resolution control determines the duty cycle or the ratio of on to off time of the Carrier Frequency. The effect of this control is somewhat like focusing the lens on a camera, you can make it as sharp or as blurry as you’d like.
Volume makes it go loud.
Gain distorts and compresses the signal. You can get a decent amount of grit and fuzz out of it for more squarewave synthy type stuff.
