Any Alternative to x42 tuner?

Patchbox OS MODEP
1

Hello all!

Been running MODEP on my Pi 4 pretty much daily for guitar. I just wanted to know if there were any tuner plugins other than the x42 tuner. It does seem to eat up a significant amount of CPU, and the pitch detection is very unstable. I have a much better time tuning with an Android app named “Tuner - Pitched” on my phone.

Thanks.

@KAOSS Right there with you. I wish there was a better tuner as well. Unfortunately it’s the only one available at the moment. I use my pedalboard for live performance and wound up just getting a Snark Air.

It seems like there is a tuner in Guitarix, but it hasn’t been ported yet apparently. I wonder how difficult it would be. Do you have any experience with it?

On further searching, it seems like we do have an option… kinda.

There’s even a build for aarch64. I just loaded it up in MODEP and it gives no errors when loading. However there’s no MODGUI, so nothing actually shows up on the pedalboard.

Well honestly I’ve compiled/uploaded a lot of plugins but have never personally ported a plugin to the MOD platform. I know it can be done but not sure of the specifics of how.

In the case of StompTuner at least, it doesn’t even need to be compiled for the MOD platform. There already exists a build for aarch64. Somebody just needs to make a MODGUI for it to be actually useful in the pedalboard view. I’d love to do it myself but I have no idea how it’s done.

See MOD SDK for info on modgui development.

So I gave this a try. Here’s what I did:

  • Cloned the source for the StompTuner
  • Compiled StompTuner (had to install the development packages for Cairo and FFTW3)
  • Copied the stomptuner.lv2 directory to an “lv2” directory in my home directory
  • Downloaded the modsdk docker image
  • Started the docker image pointing the image to the lv2 directory where I copied StompTuner
  • Ran the modsdk and it did indeed find the StompTuner.

However, the GUI that is supposed to appear in the plugin was not recognized by modsdk so I assume the plugin will not work in MOD. I will verify this tomorrow.

Is it supposed to show up? I haven’t gone through the documentation in detail but I didn’t see that being mentioned.

Yeah, I’m not sure how custom interface elements are handled in mod. I need to look at the current tuner since it has a custom UI
