Pikocore XL DIY

DigitalMonophonic

Born from a collaboration between Erica Synths and developer Zack Scholl, this lo-fi music mangler takes the tiny Raspberry Pi Pico original and scales it up into a proper hands-on performer with Erica's signature aluminum enclosure.

It's a full DIY kit with everything you need to assemble, including a pre-programmed board ready for action. Load up to eight minutes of crunchy 8-bit 33kHz monophonic samples via USB-C, then mangle them with tempo-synced effects like stutter, retrig, gate, and tunneling at BPMs from 60 to 300. Real-time knobs tweak a resonant filter, timestretch, volume, and wavefolding, while a 128-step sequencer handles four tracks with recording and playback—plus synth modes using 10 digital oscillators, four waveforms, low/high-pass filters, ADSR, and extras like chorus and tremolo. The color touchscreen makes navigation intuitive, with one mono audio input, stereo out, internal MicroSD storage, and a virtual pet for fun. Runs up to three hours on a single AAA battery or via USB-C, syncs with Pocket Operators, and it's fully open-source for custom firmware and hacks.

Builders love how approachable the assembly is, praising the gritty lo-fi sounds and endless tweaking potential in a compact, rugged form that fits right into portable jam sessions or Eurorack-adjacent setups.
