Very useful article. I also wrote on a blog and I talk about art, art on music and stuff like that. Take a look on http://www.emonden.co and give me some advice !

This sounds like a MIDI problem on your machine, since Euterpea supports multi-track output. Are you able to play any other multi-track MIDI files made by other programs using timidity? Does timidity give any kind of warning or error message when you play Euterpea-made files?

Carlos, I was struggling with the same error. What worked for me is this:
I added the ccap path to my $PATH environment variable using:

$ export PATH=$PATH:~/.cabal/bin/

and then install using

$ cabal install

See if this works for you

Cheers!

Vijay

The ccap file is an executable that comes from the CCA library. Sometimes, even though the CCA library is installed, the folder with the ccap executable isn’t added to the path. Try searching your computer for the file “ccap” (it can be installed in some weird places on different operating systems) and then add the folder it’s in to your system path.

Hi, I get the following error when trying to install Euterpea:

setup: Preprocessor ccap not found. Please make sure the CCA library is already installed, and ccap is in your PATH environment. cabal: Error: some packages failed to install: Euterpea-1.0.0 failed during the building phase. The exception was: ExitFailure 1


Could you tell me what the CCA library is and how should I install it?

Thank you! Carlo Nucera

Euterpea doesn’t terminate creating a midi with two or more different instruments. When i tried to play the .mid file, only perform one instrument and in a bad way.
If i try to test a music with only one instrument (can be n instruments but have to be the same type), i can hear the melody.
Why this is happening? I think is a midi problem! But why?
Other thing i can’t use is the play function. I have to test the music and open it with timidity.

Help!!

Thank you again!!

One question. Why i can’t hear well multitracks midi pieces?
For example,
test (line [Modify (Instrument AcousticGrandPiano) (c 4 4)] :+: line [Modify (Instrument AcousticGuitarSteel) (g 5 4)])

On the other side, this works:

test (line [Modify (Instrument AcousticGrandPiano) (c 4 4)] :+: line [Modify (Instrument AcousticGrandPiano) (g 5 4)])

Euterpea doesn’t admit multitracks performances, or is a Midi problem?

I play the .mid files with timidity, this way: timidity test.mid.
Thank you!

Is it possible that the Times New Roman font to be replaced with something else, e.g. Arial, in The Haskell School of Music book?
With the current font, the text is extremely transparent on tablet devices, such as Kindle DX.
Also, it would be great if the source document (LaTeX?) from what the PDF was generated will be available as well.

Thank you!

Hi,

I am at chapter 10 and am totally enthralled with your HSoM book and I greatly look forward to digging in in earnest with Euterpea.

I stumbled across this page and just wanted to wish you the best with your continued recovery.
