Thanks man. I'll forward this to Bob Keller too.
I think he mentioned in a message that he is willing to give 
developers svn access to the recent code.


Bob, could you comment on this?

Kind regards,

I'll be looking toward moving Impro-Visor to a public repository, as 
soon as I stabilize the current version, which I hope will be before 
the end of June. 

Ah that's good news. Thanks.


Is SourceForge the best bet?


I think SourceForge is good, but others might think different (I have 
little experience with it myself, others?)


Let us know when it's up there.

Kind regards

Correct, it doesn't. It is possible to add musicXML output. Anything 
is possible. However, I have too much else to do at this point in time 
to give that a high priority.


Input would be harder, because Impro-Visor has only a single melody 
line, but musicXML, I'm pretty sure, can specify polyphony, so there 
would be the issue of how to interpret that. Also, I'm not sure how 
musicXML deals with chord symbols, but that could be a second issue.

Thanks again.

I understand, time is scares these days...

Maybe other Lilypond devs or people who can work on adding Musicxml 
support could help you a bit. I will Cc this mail to the Lilypond users 
mailinglist (you have to check that app!) and the Linux dev list.


We will see. If you have questions, requests or announcements, just let 
us know. We (Lilypond and Linux users) like to stay in tune with 
Impro-Visor.

Hello,

I was able to open your summertime.mid file with 4 different apps: 
iTunes, Quicktime Player, Sibelius 5, Band-in-a-Box (all on MacOSx 
10.5). Also, all of the many .mid files that play from the web 
(https://www.cs.hmc.edu/~keller/jazz/improvisor/Solos/) were generated 
through the same mechanism in Impro-Visor.


I tried to run Lilypond on my platform but was not successful. While 
it says "open a menu", there was no menu available. It just constantly 
displayed a text file, and was otherwise unresponsive.


Perhaps the .mid problems are with Lilypond rather than Impro-Visor.



Thanks for your reply.
The problem is not opening the midi file, but displaying the score 
(notes) exactly the same in Lilypond.


People say, converting from musicXML to Lilypond is more easy then 
converting midi, but Impro-visor doesn't have musicXML support right? Is 
it possible to add that?


About Lilypond. I've only experience with it on Linux, but many people 
use it on Mac too.


Lilypond is text based, so it doesn't have an GUI, all though there are 
GUI's like Musescore or Rosegarden for example. So Lilypond can't open 
midi files, but the software contains an little script tool midi2lily, 
which is able to convert midi to Lilypond score.


To make working with Lilypond more easy, there is Lilypondtool: 
http://lilypondtool.organum.hu/


Note there is an very nice documentation about Lilypond on the website.

Maybe it's good to subscribe to the Lilypond user mailing list, it's a 
great way to learn about the great possibilities of Lilypond and for 
support too.


http://lists.gnu.org/mailman/listinfo/lilypond-user

Would be great to have Lilypond export function in Impro-visor, or at 
least MusicXML!




Kind regards,

Yes, this is the home of Impro-Visor.

It is GPL.

There is no Lilypond export to speak of, although it should be  
possible. However, I don't believe I can work on it myself, as there  
is too much else to do at the moment.


In the next release, we will be redirecting questions to the Yahoo!  
impro-visor forum and improvi...@cs.hmc.edu will be phased out  
(because it attracts too much spam).


I'd be happy to answer any other questions.
