Hi Alex, Whenever I want to do sound based programming in Java for wave files or MIDI, I use JavaSound. JavaSound is a little complicated to get started, but once you have a few basic things down in your head, you can play wave files, midi files, do custom sound synthesis, and pretty much whatever else you want. Here's a link to the programmer's guide: http://java.sun.com/j2se/1.5.0/docs/guide/sound/programmer_guide/contents.html Andy __________ View the list's information and change your settings at //www.freelists.org/list/programmingblind
