I'm not sure it ever supported MIDI either? Check out JNAJack, which should work OK on Raspbian, although I haven't tested it. https://github.com/jaudiolibs/jnajack There's a binary JAR under releases. You'll also need JNA - https://github.com/java-native-access/jna There are examples of usage for JNAJack, including a MIDI example, at https://github.com/jaudiolibs/examples/tree/master/src/main/java/org/jaudio… Best wishes, Neil -- Neil C Smith Artist & Technologist www.neilcsmith.net Praxis LIVE - hybrid visual IDE for creative coding - www.praxislive.org
