Dual-deck looper with touch pads, CV and clock I/O, running open firmware on a Daisy Seed
Spotykach is a dual-deck performance looper from Synthux Academy, the company's first finished instrument rather than a kit. Each of its two stereo decks has reel, slice and drift modes, with 12 touch pads, CV and gate inputs, a clock input, two modulation sources, MIDI I/O, a headphone output and an SD card slot for saved tapes. It runs on a Daisy Seed, with audio hardware at 48 kHz and 24 bits, and is powered over USB-C or a 15 V supply.
The official firmware is open source and Synthux invites forks. Unlike the other Synthux instruments, Spotykach uses its own bootloader (the repository carries bootloader-spotykach-v2.bin) that accepts USB DFU updates only on the USB-C port on the rear of the main PCB, not the port on the Daisy Seed. Use a data-capable cable, hold Reset on the back for about three seconds until the lights under the bottom pads breathe white, then flash the .bin. The official README warns that a bad flash can temporarily brick the unit until the bootloader, the firmware or both are reinstalled. Alternative firmwares replace the DSP but keep the same panel and bootloader.
Fork of the official firmware that turns the Spotykach into a platform with swappable DSP engines, from granular looper and delays to drum machine, Plaits, Rings, Csound and ChucK builds.

Experimental fork of the official 1.2.0 firmware where deck A switches between sound and effect engines such as an Audrey II voice, an oscillator and a Benjolin.
Browser app for converting, trimming and organising samples into the 6-tape, 6-slot card layout the Spotykach expects, with sample packs and an editor for its config.txt.
