I'm running Fedora Core 4 (ALSA seems to work great with my device) and C as the programming language. Host A - Local LAN - Host B | | Yamaha Yamaha Keyboard Keyboard My questions are: 1. How to calculate elapsed time data traverse from Yamaha to Computer ? 2. How to calculate elapsed time data traverse from Host A to Host B (i'= m just guessing maybe i could use ping to show RTT?? is this the correct answer?) 3. is there any other processes i should calculate ? 4. What realtime kernel patch should i use? 5. How long (in millisecond / second ??) should the total elapsed time be= , to make the realtime playing feasible?
