This will be more of an instructional video on the ZOIA. We’ll take a look at a few important concepts as well as going over the basic operation of the “pedal” and it’s modules. We’re going to build three effects here: An envelope controlled tremolo, a dual pitch shifting delay and a stereo chorus. They’ll be made from the ground up (not using preset effects) and will go step by step. Feel free to follow along and pause the video as you work.

0:00 Intro
0:28 Envelope Tremolo (LFO, VCA, ENV follower)
3:20 Dual Delay with Pitch Shifting (delay lines, filters)
8:35 Stereo Chorus (cv multiplier, cv values, modulated delay lines with an LFO and stereo outputs)
11:53 Outro (footswitch tease)

I’m making these videos to help people like me who don’t have a deep understanding of modular. I’m just a guitar player will with a little bit of CV knowledge. This will showcase (on a simple level) what the ZOIA is capable of if you spend some time with it. I hope it helps :)

Here’s the files for each section if you want to download them and fire it up on your ZOIA. Feel free to tweak things and mess around with the settings. Especially with the CV multiplier and value controls. Those are important for setting ranges to sweep with an LFO. Of course, ask any questions you might have, I’ll try my best to answer them.

Easily the most simple effect. I used an LFO to control a VCA, which is just like turning a volume knob back and forth. I also added an Envelope Controller to the LFO…. so your playing dynamics affect the speed of the tremolo.

Hello (dual pitch delay):

Super simple. The input goes to 2 separate delay lines, running is parallel.. One delay line (the slower one) goes into a filter and the 2nd delay has a pitch shifter in the line.


Chorus (stereo with drunk button):

This is slightly more complicated that the other ones but still not crazy. It’s built just like how a normal chorus works. The dry signal is mixed with 2 short delay lines. Each delay is modulated slowly with an LFO (different rates and ranges). It uses a few CV modules to set the range of the modulation. So with each of these delay lines slowly modulating, you get that typical chorus sound. Each delay goes to separate right and left channels (one has the audio inverted). This one also has a neat little footswitch trick but I didn’t go over it in the video… maybe another day :)
