Open Jam Box with Joaquin
This is an update on the process building a 4-track loop station that is meant to be played collaboratively by up to four people. In order to ensure the collaborative nature of the hardware, the looper has four sides with four identical interfaces. It consists of two buttons each, one for recording a loop and one for playing it. The tracks can be layered indefinitely, which is enabled by the Raspberry Pi 4 acting as the heart of the instrument.
For the hardware, see here for repo and here for 3D files. All files CC. We used 3mm clear acrylic, cut at 65% power, 0.3 speed and 22000 Hz frequency on a Trotec Speedy 100. Software based on Raspi Looper by RandomVertebrate.
