Three parallel distortions that can be mixed, panned, and delayed separately.

This patch is inspired by the Beam Splitter from OBNE, where a mono input goes to three differently voiced distortions and each one goes to its own output jack. Of course, ZOIA only has 2 outputs instead of 3, but that’s okay cause with a simple panning option you can actually spread your 3 voices across the stereo field in a more subtle way than with the Beam Splitter.
And that’s about the only thing that’s ‘subtle’ about this one; the 3 distortions are set to Classic, Plexi and Edgy, and all three go from low to extremely high gain (I didn’t bother emulating the voicings of the OG pedal). The 2nd and 3rd distortion channel have a delay in front of them that can be modulated with smooth randomness.
The gain is controlled via a nice little UI with indicators; just push the GAIN UP or GAIN DOWN pushbuttons, no need to use the encoder.
So, it’s probably not that close to the OBNE pedal, but you can get some thick walls of distortion or crazy noisy soundscapes from this! If you like the idea of 3 parallel distortions, give it a try.

[OVERVIEW]
-Input/Output: Mono in/Stereo out
-CPU load: Around 101%
-Build: Initial version built with firmware 2.80
-MIDI: Unused
-CV Inputs: Unused.
-CV Outputs: Unused.

[REVISIONS]
1.0: Initial patch.

[CONTROLS]
The main controls are on PAGE0 and are labeled (see below for a “Picture Manual” in the comments). Additional controls and the Stereo Output module with gain parameter is on PAGE1.

There are 3 sets of controls, one for the PURPLE voice (nr1), the GREEN voice (nr2) and BLUE voice (nr3), most controls are identical per voice:
LVL (sets the level of each distortion voice)
ON-OFF (toggles each voice on/off; if no voices are on, it jumps to bypass)
PAN (sets the stereo panning of each voice)
GAIN UP/DOWN (pushbuttons to increase/decrease the gain; keep pressed to ramp up/down)
LEDs (indicators of gain amount)

For the GREEN and BLUE voice only:
TIME (sets the delay time; max 500ms)
FBCK (sets the delay feedback; found on PAGE1)

In the PURPLE voice’s column:
MODULATE (sets the smooth random delay time modulation of GREEN and BLUE channels)

ZEBU LEFT button = Toggle bypass.
ZEBU RIGHT button = Unused.
ZOIA LEFT / MID / RIGHT stomp = Toggle each voice on/off; if no voices are on, it jumps to bypass.

[PATCH STRUCTURE]
Not much to explain here; it’s just 3 OD modules in parallel, each with a panner and two of them with a delay line and VCA for feedback. The delay lines don’t self oscillate but the feedback goes pretty high.
For the random modulation, I’ve made it so the speed decreases as modulation depth is increased (this way you only need a single control, nice and intuitive).

The most complicated thing was probably the user interface, which uses one fast LFO and three S&H modules to set the gain for each voice. And for each S&H there’s an UP and DOWN button on PAGE0. This allows for easy control of the gain levels, and it even allows all three channels to be changed simultaneously (something you can never do with the encoder).
When gain is increased, levels are automatically brought down (via an Inverter) to prevent extreme volume jumps at higher gain settings.

[TIPS/TRICKS]
>>> Throw some gentle pads or ambient sounds at this thing and slowly increase the gain levels to smash it into oblivion.

[THOUGHTS/IDEAS/PLANS]
This was a fun patch, I just wanted to get a little taste of that OBNE pedal without spending the money on something I know I wouldn’t use regularly, but it’s more fun than I thought to throw stuff at it and see what flavours of destruction you can get. It’s surprisingly good at (dirty) ambient sounds as well!

If there’s any bugs/questions/remarks/requests or suggestions for improvement, please let me know!
Enjoy!
