Euterpea has a function called "test" that writes a Music value to a MIDI file called "test.mid" in the working directory. However, to do this, Euterpea uses Codec.Midi from the HCodecs library to first create a Midi value and then write a .mid file. Unfortunately, Codec.Midi seems to have some bugs in the .mid file conversion, and, as a result, the .mid files are readable by some programs but not others. If you are on Windows, SynthFont (free) is usually able to open the files without problems. -----Donya Quick On Tue, Mar 5, 2013 at 6:10 AM, CK Kashyap <ck_kash...@yahoo.com> wrote: > Wow ... it looks much better now!!! > > Thank you so much for your feedback Professor Hudak. > > I have not been able to figure out the way to dump the output into a midi > file though. > > Regards, > Kashyap > > ------------------------------ > *From:* "Hudak, Paul" <paul.hu...@yale.edu> > *To:* CK Kashyap <ck_kash...@yahoo.com>; "haskell-art@lurk.org" < > haskell-art@lurk.org> > *Cc:* "Quick, Donya" <donya.qu...@yale.edu>; "Hudak, Paul" < > paul.hu...@yale.edu> > *Sent:* Tuesday, March 5, 2013 11:04 AM > *Subject:* RE: [haskell-art] Review request > > Hi Kashyap.
