Hello the list. I'm new on directx, and i'm interested by directmusic cause I'm doing a midi editor prog. But after looking it I 'can't see how to pass custom midi message on tracks and so on make segment for using effects features and the other stuff.... Tell me if I'm wrong , but the only way to pass datas on tracks and segment is to load a file , a script or a resource. I need to pass buffers that my sequencer generated. I can't see any exemples to do this, Is it possible ? Is it possible to create my Own "pattern" in real time and use it on a track ? For now I'v made my own pattern and track classes, and I'm using DX8 only for port and timer features. The port give me Midimessage that a record on my pattern buffers , and create tracks whithe it, next I pulse the messages directly to the out ports, But I can't use segment and tracks features..... Your help , tutorials and sample codes are welcome. Thank you all
