This page is part of the av_studio collection.

This article was written after I published my Ableton Push 3 Standalone review. You should be familiar with that article before reading this one. Note: P3S is an abbreviation for Ableton Push 3 Standalone.

The P3S runs a custom Linux distribution, which looks like it might be based on the Yocto Project. The Yocto Project is an open-source collaboration that provides tools and methods for building custom Linux-based systems for embedded devices. If true, this would allow Ableton to tailor the operating system specifically for the hardware and software needs of the P3S.

Linux Processes

I was curious to know which processes ran on the P3S, and if a firewall was installed. The ps command showed me all processes, including thread managment, memory management, task management, audit logger, Linux device tree manager, network management, swap management and running spplications.

I was surprised to see processes from the KVM type-1 hypervisor; the P3S only has an Intel i3 processor, and it is running a realtime application.

I also noticed the mention of sentry.io, however the URL referenced is no longer valid.

Another time that I looked at the processes while a Live set was loaded, I saw these processes:

The kvm module is not loaded, so the hypervisor is not active. I might look into this further at some point.

General Comments

The X display manager is xfce, a lightweight but capable desktop environment. Gnome Keyring is used to store secrets, passwords, keys, certificates and make them available to applications.

/data/logs/PushWebServiceCli.log is helpful for debugging system problems, however this file seems to grow forever, eventually filling the drive. Other log files also accumulate forever:

Shell

$ ls /data/logs/
Push3.log                launcher.log             launcher.log.2024-05-28

launcher.log.2024-05-24  launcher.log.2024-05-29  launcher.log.2024-05-31
launcher.log.2024-06-02 

The file system information was interesting:

Push Software

/opt/push3/XPython3Exe executes /opt/push3/push3-launcher.pyc. This process is launched at boot time by /etc/init.d/push3.

The software update process (swupdate) is launched by /etc/init.d/swupdate.

I could not help but see what happens when I attempted to launch Live on the P3S from the command line (it was already running):

Shell

ableton@push:~$ /opt/push3/Live -h
qt.qpa.xcb: could not connect to display
qt.qpa.plugin: Could not load the Qt platform plugin "xcb" in "" even though it was found.
This application failed to start because no Qt platform plugin could be initialized. Reinstalling the application may fix this problem.

Available platform plugins are: eglfs, linuxfb, minimal, minimalegl, offscreen, vnc, xcb.

Aborted 

/etc/passwd

The P3S uses the standard Linux user management system. The /etc/passwd file contains the list of users and their information.

• ableton is the main user, with home directory /data.
• root is the superuser.
• rsync is the rsync server user.
• sshd is the SSH server user.
