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 soundchip with 3 analog filters and a true random noise generstor, using only a few passive external components.
The cart is covered with standard 8mm grid plastic tiles in random colors that can easily be replaced with compatible parts such as LEGO®, BlueBrixx etc.
Nanoloop mono is a stepsequencer with per-step control for all parameters. There are 8 banks of flash memory each of which can hold 15 patterns per channel and a song structure.
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 to generate sound on the cart and play it through the headphone output on a completely analog signal path.
External Audio Port
Additionally, audio is also available through a mini jack port on the cart. The raw signal is rather strong and there is no volume control, it is hence best used as input for a mixer, active speaker etc.
DMG (original Game Boy)
clean and bassy
Game Boy Pocket
less bass, hiss
Game Boy Color
Game Boy Advance / SP
DS is not compatible
Analogue Pocket is not compatible
For use with headphones, only DMG can be recommened.
Nanoloop mono offers the same sync options as nanoloop one.
