VCVrack on Raspberry Pi

Here is how to install a full build of VCVrack onto a Raspberry Pi.
Go to Releases · hexdump0815/vcvrack-dockerbuild-v1 · GitHub and download the latest armv7 build(tar.gz).
Extrackt the archive (pun intended) into a folder of your choice.
cd into that folder in the terminal for example
cd /home/pi/Documents/vcvrack.armv7l-v1
and then use ./Rack -d to run it.
Play around with the audio settings particularly the block size and sample rate to get rid of pops and clicks. Also if you change Engine → Threads to 4 performance is much increased.
It helps to not have any other programs open at the same time. Let me know if it works/doesn’t - I played around with many settings and I think I left them all at default but who knows?

Old instructions - miRack

Ok, here’s how to install VCVrack on a Pi(3+ or 4 seems to be recommended). I used miRack, a lightweightish port of VCVrack to ARM and iOS devices. Start with a fresh Raspbian image.
Open the terminal and paste in:

sudo apt-key adv --keyserver --recv-keys CEF86DEA

and hit enter.
Then paste:

echo deb stretch main | sudo tee /etc/apt/sources.list.d/mifki-mirack-repo.list

Now run the usual

sudo apt update && sudo apt upgrade

and then install mirack

sudo apt install mirack libgles-dev

Next you need to enable the experimental graphics driver

sudo raspi-config

then Advanced Options → GL Driver → GL(fake KMS).
Reboot for good measure then /opt/miRack/Rack to run the software.

For more info on installing, see Release Debian Packages · miRackModular/Rack (

Have fun!

EDIT: If you have already installed this, then it’s ok, use it. If not, I’ve found the repository for ‘official’ VCVrack that I used on my corrupted SD card. Updated instructions incoming!


Good work here. Thanks for the guide.

How well does it run on a Pi 4? How many modules could one expect to reasonably run?
Might be interested in making up a panel or 2 with 7" screens as kosmo modules… I suppose there would also need to be a small amplifier circuit to boost the audio signals from the PIs up to synth levels…

Ohhh heck yeah! Hmmm im tempted to tank my mobile data for this =P
May as well, ive got my BSP with me =D

I’ve not pushed it to its limits but on a Pi 4, probably around 40 ish. My SD card decided to corrupt itself last week so this way seems a lot hackier than before but it works just the same.

Oh, and miRack seems to run on iOS as well, I might try it in the iPad too.
Edit: no, I’m not paying 9.99 for free software!

Just sold a spare 3 :frowning:
Should I convert my 3 that’s supposed to be for OCTOPI to VCV… Hmmm.

You seem to suggest that miRack is the same as VCVRack. As far as I know, it is not.

While I was making a plugin for VCVRack I got a message about the relisencing of VCVRack the reason of which was explained here: Postmortem on Rack's GPL relicensing - Announcements - VCV Community.

Apparently VCVRack changed its licensing because of miRack which seemed to be a
commercial version of VCVRack and there was a licensing dispute.

Since then VCVRack has changed its architecture quite a bit. So as far as I know version 1.x modules would not run on miRack.

Or are you referring to something else which coincidentally has the same name?

I don’t have the original post but somebody from Facebook posted this a few months ago, super awesome! I think he/she said it was a cheapy display from AliExpress.


So, how is VCV and Pi interacting with your modulars or sound gear, or is it not?

I’ve had a poke around for audio boards or something that would give CV’s in/out and audio paths and still leave some basic IO for controls (rotary encoder, push buttons, and a small LCD or TFT), that I could build some small synth utilities with a Pi. There’s some opensource synth software (forgot the project, but I think O_C use it as do a few other super expensive small devices).

(Reposted this from other thread)

Looks good. Glad that MiRack is properly Free software now, they were being shady with the licensing for a while, leading to a dispute with the developer…

No, I don’t use it with the modular - I use it for experimenting with complicated modules so I can find how they work (mostly before buying/building eg Braids). I also use it extensively as a ‘hardware synth’ in my DAW so midi from laptop to pi and audio from pi to laptop. I can’t figure out how to do this with mirack as atm I’m using it as a temporary measure until I can get back my full build of VCVrack on the pi (sd corrupted :frowning_face: ). I know mirack doesnt work with some 3rd party modules for VCV, but the few that I do need play along nicely.

Okay… I’m keen on Pi etc for sound processing, and using as sources or filters. I just don’t get on with desktop music software :man_shrugging:t3:

I like to knob twiddle and do stuff. Plus I like the organic noise you get from ropey potentiometers

With full VCVrack it is not so good, 15ish modules seems to be the limit for me at least. But @BratAttack there’s a limit to how many modules you can fit on 7 inch screens right :smiley: .
ETA: New instructions now live!

With a relatively small processor you might have more fun using Pure Data, or even Max on Wine.

A hidden advantage here is that you can run Linux applications (including Wine) on a headless Pi and tap in using a laptop over X11. Connect some knobs and buttons to the Pi’s GPIO pins for extra tweaking fun.


Beat me to it! Haha.

Okay, so Norns and Teletype by Monome are both opensource, and can run on Pi. They also use Supercolider for sound processing… I would be surprised if many VCVrack modules didn’t use Supercolider.

They’re more interesting to me, as components in a rack vs emulating a rack


I made a small patch with 18 modules including audio out and recorder. It was a bit laggy when I added the last couple of modules, and recording was very laggy, but the final file turned out flawless. It didn’t help that I had firefox open at the same time though.

Yeah, by the time i got to 7" screen my thinking had already shifted to individual VCV guest modules in the rack. I hope they come out with that multi-soundcard support so we can just jam a bunch of cheap USB soundcards into a mini hub and spam the bottom of panels with jacks under a screen.

Sweet it runs!
To make life easier for myself I created a script on my Desktop to run VCV Rack at a double click.

To do this, Navigate to the directory you want the script. For me ‘Desktop’ was the best place.

cd /home/pi/Desktop

Now, create a Nano text file with .sh as the extension.

sudo nano

In this created file, enter the following:


cd /home/pi/VCV/vcvrack
./Rack -d

NOTE: The file path for you may vary depending on where/how you extracted it.
The goal here is to locate and run ‘Rack’

Exit and save by pressing Ctrl+X.

Now we can turn ‘’ into an executable.

sudo chmod -x

Run your lazy script either by:-
Changing directory through terminal.

cd /home/pi/VCV/vcvrack

And using ONE of these:

** OR **

Just double click your newly created script from the Desktop =D BAM!

Who needs to waste time typing things anyways… right?
Hope this helps you save time and get to Bleeping them Bloops faster =)

If it didnt work… have a look through this guide and give it another ‘Bash’ :stuck_out_tongue_winking_eye:
