(Speaking from long experience as gigging guitarist and bassist). The GA-1 tuner I mentioned isn't a true chromatic tuner, but its ability to shift the standard guitar tunings down several semitones is very useful. In modern metal genres C or B tunings are probably more common than the standard EADGBE, so this isn't just an edge case.

A Korg GA-1 tuner can go down to 5 semitones flat. It's quite common in the heavier styles of rock music to downtune a few semitones.

There seems to be a general consensus (and elsewhere too) so I'll check nobody actually *is* using extreme settings for some reason, and maybe tame it down a bit. For tuning, anything greater than half way between semitones can be acheived with transpose. Or, to put it another way, if you need to detune by that much, you are really playing in a different key. -- Len Ovens www.ovenwerks.net ___ Linux-audio-dev mailing list Linux-audio-dev@lists.linuxaudio.org https://lists.linuxaudio.org/listinfo/linux-audio-dev

There seems to be a general consensus (and elsewhere too) so I'll check nobody actually *is* using extreme settings for some reason, and maybe tame it down a bit. As an aside, doing further reading it seems most authorities consider 5 cents to be about the limit for people to detect pitch change (lots of caveats of course) yet Scala example files have figures with 10^-6 cents, and Yoshimi has 10^-6 :o -- It wasn't me!

Re: [LAD] 'A' note Tuning Range
PS: +-50 Cent makes sense, since it's half of a semitone interval, see the Information taken from http://www.sengpielaudio.com/calculator-centsratio.htm: IntervalFrequency ratiocents Semitone or minor second1.059463 : 1 100 Here's a Table of Cents Difference for some frequencies close around 440 Hz: Frequency Difference 435 Hz −19.78 cents 436 Hz −15.81 cents 437 Hz −11.84 cents 438 Hz −7.89 cents 439 Hz −3.94 cents 440 Hz ±0 cent 441 Hz +3.93 cents 442 Hz +7.85 cents 443 Hz +11.76 cents 444 Hz +15.67 cents 445 Hz +19.56 cents So, the conversion factor 4 cents / Hz is valid for the purposes of tuning as an exception only very close around 440 Hz. There is no conversion from Hz to cents and vice versa. Statement: Cent is a logarithmic unit of measure of an interval, and that is a dimensionless "frequency ratio" of f2 / f1. ___ Linux-audio-dev mailing list Linux-audio-dev@lists.linuxaudio.org https://lists.linuxaudio.org/listinfo/linux-audio-dev
Re: [LAD] 'A' note Tuning Range
Without doubts it should be 440 Hz +- 50 Cent. +- 50 Cents is what the meter of the BOSS TU-12H chromatic tuner displays and what you'll find for other software synth, such as e.g. iSymphonic. The BOSS meter's Hz labelling is from 430 Hz to 450 Hz and the Hz labelling of iSymphonic from 428 Hz to 452 Hz. IOW the Cent labelling range from - 50 Cent to + 50 Cent is a little bit more than the HZ labelling range from 428 Hz or 430 Hz to 450 Hz or 452 Hz. ___ Linux-audio-dev mailing list Linux-audio-dev@lists.linuxaudio.org https://lists.linuxaudio.org/listinfo/linux-audio-dev

Apr 9 2019, Will Godfrey has written: ... What have other synth people here set for this? Does anyone else actually have the setting? ... Not that I write a synth, as well you know. :) In some synths I've seen it fixed to certain values, related to old tunings. +/- 1/2 octave seems generous. I've mostly seen that used in relation to orchestral instruments and - of course - organs. In practise, the lowest value for A I know of is 392, but I think someone mentioned that there is even a slightly lower value than that going to (almost) f. Upwards, I only know of 441/442Hz as "American concert pitch". Not being a guru of any description, permit for a slightly wider range. :) Aside: that might be a lovely combination, a concert for harpsichord, ceelo and Yoshimi.

Currently in 'Scales' Yoshimi can set this anywhere between 1Hz and 2kHz, which is frankly ridiculous. This doesn't appear at all in the Scala documentation, so that's no guide. I've had suggestions ranging from +- 1/2 semitone to +- half octave as being more than enough, considering that there is also semitone master key shift covering +- 3 octaves (used to be 5!) along with a fine detune of +63 -64 cents.
