Chords over 2 octaves

[Sherry C]

Hi Martin,

Thanks - this may prove quite helpful. There is indeed something different about the notes between the two files, which is one reason it's so important for us to know as much detail about a situation as possible.

If you open both your file and my file, and use the Format/Display pitch names in noteheads, you'll see a difference. In my file, there are no accidental symbols that show up. In yours, though, some naturals show up (the default setting for the "show pitch names" is to also show accidentals that don't normally display.)

This tells me that there is indeed something "under the covers" that is different between the files.

So, my next question is, does your keyboard have any kind of automatic transposition feature, and was that feature "on" when you did the step-time recording? If it has such a feature, and it was on when you recorded this file, please try turning it off and then record the same notes. Or if not, please let us know that, too.

Thanks for your help here!

My keyboard is pretty basic so it has no transposition facilities.

I thought to export a midi file of my previous .not file and look at an event list.
The results shown in the attachment are a bit odd. For example where do the Key Aftertouch messages come from. I do not have Key Aft ability on my keyboard. And why are there repeated notes at the beginning.?? Something strange going on.

ps
I just produced an event list from your .not file where you show accurate chord names. I got the same result (ie with key aftertouch etc). So although this is unexpected, it is nothing to do with the chord name transcription evidently.

Hi Martin,

Not sure what MIDI event tool you use. From my perspective (except the missing chord) the Midi event list looks clean and OK. Please see the screen shot.

I use Cakewalk Sonar for the event list. It was just a thought I had that it might show up something to help with the missing chord problem.

Thx. In order to double-check the event flow, I recommend to see what the MIDI-OX tools says. Btw. a great tool. Please find the tool here.
Could be that when recording not all MIDI events are captured. Anyway, I think that such a case is not related to chord recognition.

Thanks for the tip about midiox. Ill definitely give it a try.

I've uploaded another file to show missing and incorrect chords. Clearly the first F and G are missing and the the third chord G7 is incorrect. Sherry mentioned earlier a point about accidentals when selecting the "note names in note heads" option. There are none in this example as you can see.
