I’ve posted a guitar tuner on Patch Storage:

Was thinking this would really benefit from a change to the UI - how would I go about displaying a horizontal meter on the screen? (similar to [hslider]), so I can mimic a standard analog guitar tuner display with a needle, i.e.:
To make that kind of slider graphic / animation you would use [until] into a float counter run into scaling / location math into the shape / line primitive /oled/primitive symbol.
Check out the first post in the Organelle GFX post. The path running down with the [r num-down] is essentially what you will want to build off of. Possibly 2 or more of these signal chains to make it look nice.

Great, thanks, will take a look. That is the thing I love about Pd / Organelle, there’s always something else to do / learn. 
Super awesome!
New version on Patch Storage with a graphical interface (oops, had missed out a couple of loadbangs, now added):

Very nice, works very well.
The next step is one that works polyphonically, all 6 strings at the same time

It tracks very well! did you change anything in the audio path from the earlier text version? or maybe just having the graphics help make it so much more intuitive.

Thanks! 
Yes, it didn’t track so well with the graphics using the continuous stream of control output from [sigmund~] but worked a lot better once I put this through [sig~] and into [snapshot~] which I banged every 100ms.
If anyone’s interested I have just posted a 432Hz version on Patch Storage:

Hi, great tuner. Works very well for the guitar. What would it take to make it work for a 5 string bass?
Best
