MIDI guitars have been around for a while, and have been seen on stage with the likes of Pendulum for years. Here we have a an incredibly opulent "DIY project" which uses an Atmega 32U4 to process data on a touch sensitive board, which is eventually converted to MIDI. It's a whistle stop tour of a project which must have taken a good couple of months. There's more on the design over on Hackaday, and it's avail;able to buy for around $800 on Misadigital.
The Quadwave is a streamlined, next-generation digital guitar MIDI controller that lets you play sounds no guitar or bass can. No strings to tune, no moving parts to break - just a lightning-fast capacitive neck and a powerful multi-touch pad that transforms how you play.
Unlock playing styles no keyboard can touch - like blistering metal-style tremolo picking just by tapping on the pad. And because the pad modulates synth parameters before the note triggers, every tap can shape a different sound, giving each note its own identity in a way keyboards simply can't.
Designed for the stage, tuned for the studio, and built to push your synths to their limits. Whether you're sliding into soaring leads or morphing synth textures with your fingertips, the Quadwave gives you power, speed, and control like nothing else. Plug it in. Feel it. Own it.
Here are a few words from the creator...
I built a futuristic digital guitar with NO STRINGS - and in just 5 minutes you'll see the entire journey: schematic, PCB, firmware, and a live jam. Why? Well... you know how it's 2025, but it doesn't really feel like it (because we don't have flying cars)? Ok... so we can't have flying cars, but what can we get? That's right, futuristic guitars. Demo song at end is a cover of Flint – Fooling Myself.
It's good, but it's not exactly a MIDI Leg is it?!?
