Topic: First note of keyboard shows as A-1 in midi, not A0

Looking at incoming notes in the PTQ midi stream, A0 shows as A-1, i.e. Note 21 On (A-1)  and top note as C7.

I can see them as bottom and top notes on the PTQ keyboard, and they certainly sound just fine.

Any idea why? I'm certainly sending the correct notes, according to midi-ox, and have no transpose

Never noticed it before. Just a bit off putting.

Hi,
should be okay, according to the manual:

The thing is that there are some discrepancies on octave labels among DAWs and virtual instruments. In Scientific Pitch Notation, the middle C is labeled as C4. However, in DAWs like Cubase, middle C is labeled as C3 while in FL Studio, it is labeled as C5. As far as I know, it's just a choice devs made on which naming convention to follow and does not affect anything.

Any idea, why Modartt is using a convention and not an international standard?
Historical reasons / early development decision?

From Scientific pitch notation:
"Alternately, both Yamaha and the software MaxMSP define middle C as C3. Apple's GarageBand also defines middle C (261.6256 Hz) as C3."

MuseScore defines Middle C as C4, but it's C3 in a lot of other software, as noted. It confused me for ages! Very frustrating.

I don't think it is a matter of choice for DAW's . Of course they are free to call any pitch the way they want, but there is a logic behind the C0 naming convention for the lower C of a 88 Keyboard . It has a frequency of 16.35 hertz , and the reason it is called C0 is because majority of persons cannot hear frequencies below 20 Hz.  In addition, worth mentionning  the magic of low notes ,in an acoustic piano , as the 2nd partial harmonic is the strongest in the spectrum and in fact the human brain reconstitute/models the bass notes based on this partial and not based on the fundamental frequency.
