Nanoloop Mono is an analogue synthesizer on a cartridge for the original monochrome Nintendo Game Boy.
Nanoloop Mono features a step sequencer with per-step control for all parameters, and there are eight banks of flash memory, each of which can hold 15 patterns per channel.
Oliver Wittchow from Nanoloop explains the technology behind the Mono cartridge: "On the original Game Boy models, one pin of the cartridge connector functions as audio input, connected to the built-in amplifier. This unique feature allows you to generate sound on the cart and play it through the headphone output on a completely analogue signal path.
"In the Nanoloop Mono cart, the analog components (op-amps, comparators, logic cells etc) of a PIC microcontroller are connected and configured in such a way that they form a hybrid sound chip with three analogue filters and a true random noise generator, using only a few passive external components."
