A few days ago the Csound crew released version 6.14. The Haiku package is now available at http://GoodeveCA.net/Csound .
((This is not the same as the Csound version you can find on HaikuDepot, which is earlier and has no live (Haiku) audio or MIDI. This package is built directly from the current Github sources – with some extras like Haiku icons.)
If you’re not familiar with the system – and are involved with creating music or audio in Haiku – you probably should be… It’s an extremely powerful music and audio generation and analysis application and language. It was originally developed by Barry Vercoe at MIT in the 80’s, based on Max Mathews’ “Music N” programs that ran on mainframes in the 60’s. It has now been advanced far beyond the original and is being continually enhanced. It does have a ‘learning curve’, but I’ve found it well worth the learning!
