Yes. In my opinion they have done a really good job.

Yes. The people who wrote this speak spanish and it flavors most of the 
code.
They produced a little documentation, but the code is pretty much devoid of 
comments.
Initially, it would not compile because the GUI (fluid) had a modification 
that
required changing a data type to long...at least for 64 bit machines. I told 
them
so...they might have fixed it with a version .27. Mostly it seems they 
abandoned it.

There are a number of things I liked about it though. It uses the gettext 
facility for
internationalization. (I didn't know about this.)

It uses the alsa routines for midi operations, so it fits well with jack.

I thought that I could enhance it for my taste. For example I mean to
incorporate block chords into the mode switch. Given a valid chord symbol 
and
a lead note, the block chord routine produces  a five part harmonization and
delivers it to the current midi voice.  Should sound like a brass or reed 
section of a big band
only using one finger.

I haven't told the gmorgan mailing list that I have tinkered with it. It is 
licensed under
the GPL2, so I have the right I think. Still, they may mind.

The wx gui is nicer that fluid I think.

I'll clean up my code a little before I send it to you.
If I tar my directory and send it as an attachment to you personally. That 
ok ?
