System Requirements

Hardware

• x86_64 (64-bit), i686 (32-bit), powerpc64le (PowerPC), armhf (ARMv7) or aarch64 (ARMv8)

Operating System

• GNU/Linux, FreeBSD, Windows or MacOS

Recommendations

CPU

For smooth operation, we recommend using a CPU with at least 2GHz clock speed and at least 4 cores in total.

Monitor

It is recommended to have at least 16 inches of monitor space to work efficiently with Zrythm.

Audio interface

An audio interface offers low latency and better quality than integrated sound cards (especially if recording audio).

MIDI keyboard

For quickly trying out melodies, recording and controlling knobs and buttons.

JACK

When using the JACK backend, JACK needs to be set up and configured before running Zrythm. You will find lots of information online about how to configure JACK, such as Demystifying JACK - A Beginners Guide to Getting Started with JACK, so we will skip this part.

Memory Locking

Zrythm requires memory locking privileges for reliable, dropout-free operation. In short, if data is not locked into memory, it can be swapped by the kernel, causing xruns when attempting to access the data.

GNU/Linux

To set up these privileges for your user, see How do I configure my linux system to allow JACK to use realtime scheduling?.

FreeBSD

To set up these privileges for your user, change the user class’ memorylocked value in /etc/login.conf.

Open File Limit

On startup, Zrythm will attempt to increase the maximum limit of files it can open. You should give your user enough permissions to allow this.
