One octave too high - Githubissues

craigsapp commented 6 years ago

For this MEI encoding:

https://github.com/davidrizo/im3/blob/develop/imcore/src/test/resources/testdata/core/score/io/kern/apel/pag101_fig1.mei

The octaves are one too high.

Rendering in VHV:

Lowering the octave by one:

Rendering of the MEI data can be viewed in VHV by pressing alt-m to go into MEI mode, then pasting the data into the text editor:

The problem is in the Humdrum encoding:

https://github.com/davidrizo/im3/blob/develop/imcore/src/test/resources/testdata/core/score/io/kern/apel/pag101_fig1.krn

The pitches are encoded one octave too high:

!!!OTL: Willi Apel, pg. 101
**mens
!Example
*clefC3
*k[]
*M4/4
*met(C)
S:ff

sdd>
mcc/

Should most likely be:

!!!OTL: Willi Apel, pg. 101
**mens
!Example
*clefC3
*k[]
*M4/4
*met(C)
S:f
<s:e
sd>
mc/
Me/

I will have to get my copy of the Apel book to verify.
