I'm confused now. :-) > Kindest regards > Julien From the Cakewalk Pro Audio 8 User's Guide, Chapter 15 page 2 Synchronization Overview Clock Source.... Timing is determined by ... -------------------------- -------------------------------- Internal The clock on the computer motherboard Audio The clock on the computer's sound card MIDI Sync The clock on the external MIDI device SMPTE/MIDI Time Code (MTC) A time code signal (in SMPTE or some other format) recorded on some external medium SMPTE is the acronym for the Society of Motion Picture and Television Enginers. In SMPTE format, time is measured in hours, minutes, seconds, and frames. When I wanted to sync Cakewalk to my Roland MIDI modules, I used SMPTE recorded to an audio cassette, with the output from the audio cassette cabled back to my Winman 4X4/S MIDI controller PCI card in the computer box. My preference was always to use SMPTE for syncing up MIDI synthesizers and hardware. I've never gotten into video work, but perhaps some of the video software available to Linux will allow you to use SMPTE for your MIDI syncing. A reference you may find helpful in MIDI programming is Rob Young's The MIDI Files, ISBN 0-13-262403-6, copyright Prentice Hall Europe, 1996. The blurb on the back jacket says: Taking a light-hearted, informal approach, The MIDI Files guides the user through the initial 'getting to grips' stage to present full and detailed sections on all aspects of professional MIDI song-sequencing. A career change side-tracked me away from completing my study of this book. But what I did get through was easy to understand, came with a 3.5inch diskette giving examples of the techniques being discussed in the book. This is the best book on MIDI programming that I've found to date. Hope this helps you Julien, Stephen Stubbs. _______________________________________________ Linux-audio-user mailing list Linux-audio-user@xxxxxxxxxxxxxxxxxxxx http://lists.linuxaudio.org/mailman/listinfo/linux-audio-user
