Re: audio drops on cop-set tcp commands

I did some brief tests playing back a single WAV file,

I used a default Nama configuration with a single use
track.[*1]

WAV -> track1 -> loop -> Master -> soundcard


While the music was playing, I tried jumping the volume by
+/- 3 dB, 6 dB and 12 dB on the "track1" and "Master"
chains.  I did this while using the ALSA sound device. Jackd
was not running.

Depending on the signal amplitude at the time, I could hear
an audible click at +/- 3 dB, and louder clicks for the
larger increments.

I wonder if these artifacts could be minimize through better
configuration. A heroic workaround would be
for Nama to intercept volume commands and try to massage
them into a form that Ecasound could execute without
glitches: a series of smaller steps executed over an
interval.   

However, that could get messy if a control surface is
already sending bursts of commands.

Speculatively yours,

Joel
