Pisound is compatible with virtually all Linux distributions and software as it comes with an ALSA audio and MIDI driver integrated into mainline Raspbian Linux kernel (ver. 4.4.27+). The support driver for Pisound consists of two pieces - the Linux kernel module and user-space pisound-btn daemon.
The Pisound button daemon is a user space program which implements monitoring of The Button on the board by registering a GPIO interrupt handler. Therefore it takes minimal CPU resources, but is still able to react to button pushes just at the moment it was interacted with. Read more on The Button functionality below.
For quickest setup, targeted at audio applications, we recommend using the SD card image of our Patchbox OS.
To install the Pisound software on Debian compatible distributions like Raspbian, run the below command in a terminal. It can also be used for updating the software:
curl https://blokas.io/pisound/install.sh | sh
This will set up the Blokas APT server and install all the software packages for Pisound. Then you may run
pisound-config to further customize your installation:
Once the system boots up, run a terminal and run:
amidi -l arecord -l aplay -l
