Polyend Endless is a programmable stereo effect whose algorithm is not fixed at the factory: it loads patches you create or download from the community and runs one effect at a time. At its core sits a 720 MHz ARM Cortex-M7 and a 48 kHz / 24-bit path with low-noise studio-grade preamps on input and output.
The effect that exists in no catalogue
When the effect you need only exists in your head, the usual outcome is a compromise from an off-the-shelf pedal. Endless closes that gap two ways: the Playground system turns a written description into a working patch in minutes, and a programmer can write their own in C++ against the open SDK in the maker's repository. Finished patches move to the device by dragging a file over USB.
One box, changing identity
Since the effect is a file, the panel legend changes too: the front plates are magnetic and swappable, with one blank plate included. A TRS expression pedal input puts a chosen parameter under your foot, and the enclosure and knobs are machined from aluminium. Power accepts 9 V DC of either polarity, which is one less thing to check when adding it to an existing board.
