Tuner?

[JayBee6244]

I don't see a native Tuner module in VM - other than using a VST host or an Andrew Macaulay module (CV Note) that works somewhat but it's not the main point of his module.

Does anyone know of any native modules for this? Tuning oscillators, filters (self-modulation) etc - all needs a tuner - and ideally something with stabilised input detection for tuning to specific root notes and octaves.

Just to clarify - you mean a tuner that detects the fundamental frequency of an audio signal (lika a typical guitar tuner)?

I am writing a CV to Hz meter at the moment, nearly ready. But again, can I ask the same question, do you want an audio frequency meter? That, interestingly, is going to be my next project

Hi @Captain @Andro,

Yes, I'm looking for a monophonic tuner (like a guitar tuner) so I can tune oscillators, sub-oscillator and filters (including external audio sources) correctly.

Examples:

Hope this helps?

Determining fundamental frequency (~= pitch) of a note is pretty complicated - that's why you don't see a lot of these modules. To give you an idea of how subtle this is see here:

Irrelevant to VM but is shows the considerations involved.

I'll start working on this, since I will have one customer! [I am preparing to release a few simple modules in the next few months.]

When you realise all the complications you can see that not all tuners necessarily give 'exact' results. It's a balance of a dozen parameters.

oh yeah, my favorite thing right now is karplus strong synthesis, and I have to tune everything by ear (because I always run vm stand alone, if I was going to get serious then I could use a DAW tuner on the audio out, but much prefer stand-alone so a tuner module would be nice)

[JayBee6244]

Same here. I run standalone with integrated hardware driving VM. Currently I have to use the host module to bring in a VST, which kinda spoils the flow.

@andro I’ll definitely be customer number one - let me know if you need any testing done ahead of release - whenever that is!

For reference VCVs HotTuna seems to be the go to’ module there and it works very well and is simple to use.

Hi there,

Is there any update on Tuner ideas - I am using Voltage Modular as a controller and FX rig for some external eurorack gear and I would love an integrated tuner module so I can tune my external oscillators and potentially make chords.

I am currently using an external tuner, not tried a VST one yet which I would need to use in my DAW.

If anyone knows of any existing modules then please let me know.

Thanks!

And yet guitar tuners have been a thing for decades, and reliable enough that guitarists use them on stage during a show.

The ESP-20 Processor module features "Freq -> Volt" conversion. It is not 100% accurate and it doesn't really work below G1 (~49 Hz), but it will get you in the ball park and you can fine tune by ear from there.
