Hello Anders, thank you for your interest in pianoscope! Compared to PianoMeter, pianoscope is faster and more reliable in measuring the inharmonicity of the full scale. Its user interface is highly configurable and makes better use of the available screen real estate, especially on small devices. It offers an overall calmer experience as it does not burden you with four simultaneous strobes during tuning. Instead, it uses a sophisticated algorithm to combine up to ten partials into a single indicator or strobe. pianoscope is far more reliable in automatic key detection. The resulting tunings are considered by many to be best of class. pianoscope pro is not only available as a one-time purchase or a yearly subscription but also as monthly subscription. I hope this helps. If you want to discuss pianoscope related issues, you can also check out the forum at forum.pianoscope.app

@pianoscope Thanks for the prompt response. Will head over to the forum later. What is it in the inharmonicity calculations that makes it more reliable?

@@aostensv When you repeat the IH measurements in PianoMeter you will find that you will often get varying results with the same string. I can only make an educated guess why this is the case in PianoMeter. My guess is that it does not perform any proper attack detection and therefore uses varying phases along a notes sounding duration to gather IH data. If you do a tuning curve calculation on this basis, you might get a sub-optimal result.

@pianoscope OK, thanks. Will try and do a side by side to see. I have a Shure Motiv MV88 mic for the iPad. Will it make a difference vs. the built-in mic, or is it negligeable?

@@aostensv You can use an external microphone, but you don't need one to get great tunings with pianoscope.

pianoscope requires iOS 15 or later. You can try to get it to run on a jailbroken device, but we don't officially support such a configuration. The oldest devices still officially running iOS 15 are the iPhone 6s, the iPhone SE 1st gen and the iPad mini 4th gen from 2015 or the iPad Air 2nd gen from 2014.

@@pianoscope6345 Thank you for the prompt response. And another question. When setting the tone, should the scale indicator be taken at the moment of hitting the string or a little later after the sound is stabilized?

@@mobile_83 The traditional approach is to tune in the steady state of a string. We are currently investigating whether focusing on the early tone phase brings any quality advantage besides the obvious time saving. We may offer a custom feature for this in a future update.

@@pianoscope6345 Dear Mark, let me make a clarification. If the task is to adjust the piano tuning (not to raise the tonality), first, we conduct a test of inharmonicity. Is this test performed on an unconfigured instrument? We get a picture of the "ugliness" of the current setting. And after that, we configure the entire tool, according to the recommendations of the program. As a result, if after setting up we repeat the inharmonicity test, then it should be close to the reference schedule? Just how does the data of the ugliness (inharmonicity) of the starting non-tuned tool help in the calculations of the program, or what is it needed for?

@@mobile_83 I don't think I understand your question. Probably this is a translation issue from Russian. Can you pose your question in Russian?
