CHOW Analog Tape Plugin


This plugin looks really interesting ! If I’m not mistaken, it doesn’t exist for Zynthian yet.

Chow Tape Model is a digital emulation of a reel-to-reel analog tape machine.

I would like to have this plugin to give a particular color to my sounds !

On the creator’s website there are several other interesting plugins, such as a phaser, Klon Centaur overdrive and a delay.

The matrix Delay may be too complicated to use but the phaser and overdrive would work well with the Zynthian.

Would it be possible to include them in the zynthian? maybe in the next update?


It’s available as an lv2 instance so it should be relatively easy.

here is a script for building - but:
The plugin needs CMake-3.15. Zynthian has CMake-3.13.4. So it will only work when updating CMake before.

sudo apt-get install --yes libasound2-dev libxcursor-dev libxinerama-dev libxrandr-dev freeglut3-dev libjack-jackd2-dev
git clone AnalogTapeModel
cd AnalogTapeModel/Plugin
git submodule update --init --recursive
sed -i 's/\s+FORMATS AU VST3 Standalone LV2 #VST/FORMATS LV2/' CMakeLists.txt
cmake -Bbuild
cmake --build build/ --config Release
make -j4
make install
make clean

I am pretty sure that the LV2 installation path has also to be fixed. Currently I have no idea where the plugins will be installed…

Thank you for the quick reply @C0d3man, always impressive !
anyone know when CMake will be updated?
@jofemodo ?

Thanks !

Chow plugins are really high quality and really recent, it would be great in Zynthian !

A way for building the cmake from the repository (and install it at /usr/local to avoid conflicts with Debians cmake (so you have to call /usr/local/bin/cmake instead of cmake)):

sudo apt-get install --yes libssl-dev
git clone
cd cmake
./bootstrap --prefix=/usr/local
make -j4 
make install
make clean

I wonder if it is time for us to set up a repository for pre-built deb packages.

I am not very comfortable with Linux code. And I’m afraid to mess around and corrupt my installation of zynthian.
@C0d3man , if I enter these lines of code into the web terminal, would I have this plugin running?
I have never done this before.

Is it better that I wait until this plugin is integrated by default? like i said i’m afraid i’ll corrupt my zynthian and have issues with the next updates.

Sorry for those noob questions!

The CHOW PHASER also looks very interesting, as well as ROBOVERB plugin that I found yesterday.
This reverb is really incredible, it gives you a metallic reverb, very accurate for the drums!

Cod3man, would it be possible to make a recipe for these plugins too?

Thank you so much!


Normally: yes. Currently: no. There is a problem when compiling the plugin. It seems that there are some compiling problems.

Yes, I think so. The plugins are based on JUCE and cmake. Unfortunately I have little experience with both environments. It may take some time to get it running…

No problem at all!

Probably yes, when I have solved the basic problem that brings the current error.

Thanks for the quick response !
Hope we can find a way to fix the compilation problem !
These plugins are truly amazing.

I share with you video presentations of these plugins, for those who are interested, @manateemilitia @Fitz @Vrtel

CHOW tape plugin is really interesting to warm up the sound, especially to make vintage effect, really interesting with piano samples.

ChowDSP is really a project to follow, the creator makes great plugins and he releases them in lv2 every time!


@C0d3man hi ! Do we have any improvements regarding the compilation of these plugins?

Thanks a lot !

No, sorry.

It seems that the code is highly optimized for Intel instructions. Adapting to ARM is not easy done - I have no time to do this…

Thank you ! I’ll ask to the plugins creators if they can port it to ARM, you never know!


@C0d3man ROBOVERB Metallic Reverb(Release Roboverb v1.1.0 · kushview/Roboverb · GitHub) is not provide by CHOW, someone else does, is compilation difficult for this plugin too? It’s the same ?
