Hey guys,

I’m slowly turning my Quad Cortex into a spaceship and now I’m considering running vocals through it too 
(Currently QC is MIDI controlled from Ableton.)

Photo 1 is basically my preset structure.
The idea would be to run vocals on Line 4 for synced delays/reverbs etc.

First question:
We agree that the small audio gap when changing presets is basically unavoidable, right?
Because if vocals are running through the QC too, I’ll obviously get the same cut there.

Even on guitar live, I already notice the little gap between preset changes — usually hidden a bit by ambient trails/fill/etc — but I assume that’s just how it is on the QC.

Now the REAL question:

I work entirely in Scenes mode.
1 preset = 1 song.

For vocals, the signal would be split with an XLR Y:

• DRY vocal straight to FOH/mixer
• FX send → QC → mixer

The issue is:
Since I’m working with Scenes, I can’t really “enable/disable” Line 4 independently (for example mute it or set volume to 0%) without affecting the whole scene structure.

Do you guys know if there’s a way to control ONLY the vocal FX path externally from Ableton?
Like sending a dedicated MIDI CC just for mute/unmute of that line/path, independently from Scene changes (CC#43)?

Basically I’d love:

• Scenes still handling the guitar/song automation
• another independent CC only controlling vocal FX ON/OFF

I could duplicate scenes with/without vocals, but I’m trying to build something cleaner and more autonomous long term.

Maybe I’m overcomplicating this and there’s an obvious solution

If anyone has ideas or a smarter workflow, I’m all ears!

Hi everyone,

I have a project idea and I'd like some feedback before I spend too much time on it.

I'd like to build a standalone hardware effect inspired by Glitch 2. Not necessarily a full clone, but a pedal/synth-style unit capable of doing things like stutter, retrigger, gate, tape stop, reverse, bitcrushing, and other glitch effects in real time.

My first thought was to use an ESP32-A1S because it already has audio-oriented hardware support and seems relatively affordable and accessible.

The concept would be:

• Audio input
• Real-time audio processing
• Audio output with low latency
• Later on, a small TFT/OLED display and a few knobs/encoders for editing parameters and presets

Before I start prototyping, I'd like to know if I'm heading in the right direction.

A few questions:

• Is the ESP32-A1S powerful enough for this kind of project?
• Are there existing audio DSP libraries/frameworks for ESP32 that would help with real-time effects processing?
• Has anyone here built a guitar pedal, synth effect, or audio processor on ESP32?
• Are there any major limitations regarding latency, RAM, or CPU performance that I should be aware of?

To be clear, I'm not trying to recreate every feature of Glitch 2. My goal would be to start with a simpler version containing a few effects such as:

• Retrigger / Stutter
• Gate
• Tape Stop
• Buffer Freeze
• Bitcrusher
• Short Reverse effects

Then expand from there if the platform allows it.

I'm mainly looking for a reality check from people who have already worked with real-time audio on ESP32. If this is a terrible idea, I'd rather know now than after writing thousands of lines of code 😄

Thanks for any advice, recommendations, or alternative hardware suggestions.
