Re: [Denemo-devel] Transpose

I am not sure if I replied to this or not. I just recently found this in
my inbox. It has been in there for a while and I had not noticed.

You did write up something to apply code to a selection with transpose.
I did not look at the code. I have it here on my hard drive. I removed
it from git because I was not sure how to remove it from a release.
Transpose was not ready because it was possibly destructive. It did not
apply to chords (simultaneous notes in GList). It also was not able to
transpose by some (can't remember which) interval. Should I resubmit it
to git?

I believe you mentioned this in an email. Yes.

I feel like that when I am very busy. Studies have shown that the same
brain chemicals are produced when a person either eats an apple or
visualizes chewing and tasting an apple. So when a person focuses on
eating an apple the mind can't tell the difference. Yes you did eat the
apple but it what reality shell.

We can integrate this into the wiki like you mentioned in another
email.
