Description
Big Genes is a 20HP Eurorack module designed for the Ksoloti Core. By adding a bunch of tactile controls with MIDI and CV input/output options, Big Genes enables the Ksoloti to be utilized as a powerful programmable module. This is a complete DIY kit to build the Big Genes. Note: You need to tick the box above to add the Ksoloti core PCB unless you already own one.
The Ksoloti Core is a rework of the discontinued(?) Axoloti Core board. In short, Ksoloti aims for maximum compatibility with the original Axoloti, with some layout changes and added features. The Axoloti Core hardware board became unavailable at some point, but because Johannes graciously open-sourced the schematics (and since the global part shortage somewhat improved) it was possible to recreate a board nearly fully compatible to the original: enter the Ksoloti Core.
Using the Patcher software on your computer, you create your own sound patches by placing and connecting sound objects, or explore patches other users shared. You can edit any existing patches and even objects, or write entirely new ones from scratch. When you are satisfied with your patch, you can upload it to the Ksoloti Core’s internal memory – or save a collection of patches on SD card – so you can play it without your computer connected.
The fun with Ksoloti really starts when you connect pots, buttons, LEDs or displays, sensors and more to control your patches and make Ksoloti a hardware instrument – Big Genes aims to do exactly this within the playground of a Eurorack environment!
Full information on getting started with the Ksoloti can be found on Ksoloti github here: https://ksoloti.github.io/
All SMD parts on the PCBS are already pre-soldered
