Lonesoulsurfer Acid Drip is a new Raspberry Pi-based open-source DIY groovebox with a built-in acid bassline synth and drum machine.
There’s a groovebox for every budget, from entry-level to premium models. Those on a tight budget can also check out the numerous DIY projects. With a little technical know-how, you can build some interesting instruments. Here is a new one.
Marcus Dunn, aka Lonesoulsurfer has created the Acid Drip, a new open-source groovebox.
Lonesoulsurfer Acid Drip
Acid Drip is a little groovebox that consists of a bassline Synthesizer and a drum machine.
At the core of the Lonesoulsurfer Acid Drip is a Raspberry Pi RP2040 that powers the instrument. This is a popular low-budget microcontroller for DIY projects like this one.
The acid bassline Synthesizer is based on the Badass Bass, a 10-year-old open-source bass synth engine, while the drum machine core uses Matt Bradshaw’s DrumKid, which has a Lo-Fi character. Both instruments are built on the Mozzi audio library.
Alongside the bass and drum engines, it also includes a 16-step acid sequencer and a 16-pattern drum groove generator. This gives you two instruments in one device that run simultaneously on dual cores.
The hardware features a 320×240 ILI9341 TFT display and 16 Cherry MX pads. Plus, you have parameters for the cut-off, resonance, and delay for the acid synth engine.
On the connection side, it has a 3.5mm main output and a sync input on the front panel.
According to Lonesoulsurfer, the images show the V1. There is already a version 2 with a slightly different design, including an extra pot for the mixer.
First Impression
At first glance, a nice, appealing DIY project. I like the form factor of the Acid Drip groovebox.
Lonesoulsurfer Acid Drip is available now as an open-source project on GitHub.
