First of all; we
need to define our target at which we want to sound everything together.
Since we are interested in the mixer’s output we’ll use that.
|
|
•The mixer adds some delay, d1 to all our
sources. in case of this analog desk this more of a theoretical issue though
|
|
•The microphone adds some more due to acoustics
|
|
•The playback stream is more interesting for us.
We have buffering in the application, ALSA library, PCI buss and D/A
converters
|
|
•Flow is similar for the MIDI stream, but in
this example the MIDI device is relatively slow; a thing to consider!
|
|
•Similar to monitoring (including acoustic
delay) and recording, where we again see the effect of buffering etc.
|
|
|
|
Adding a 2nd
external midi device gives an interesting situation. The 2nd
device faster than the 1st, resulting in different delay. Special
handling in the MIDI dispatcher is required to compensate for this.
