That's true.

I see it like this. A unit for live sound is adjusted once for the 
combination of speaker units and amplifiers. Then only minor teaks may 
be needed for certain halls, but in most cases it's not necessary.  If 
all is adjusted, lock the unit and bury the password. There is a reason 
why these DSP's have so few knobs.

Mastering is different, each song is different and even the same song 
can be made different just by tuning Jamin. Jamin does a good job and 
works well combined with Ardour.

I see it as two whole different things even if a lot of processing is 
the same.

I guess if I would design a software DSP based on Jamin technology, I 
still would like it to be so that no one passing by that computer can 
change any setting. It's just needed once and is mostly stacked away in 
the amp racks too, so it's not in range of the FOH mixer.

I don't think it's fixed. It must be from slow hardware days where 
everyone advised to use 1024 to prevent xruns.
But that's not the largest delay in Jamin, it's the brick limiter that 
has the long delay. But if you shorten the delay the bass frequencies 
will distort, I even use a longer delay that the default. No problem for 
studio work, but unacceptable for live.
Turning the limiter off leave you only with the 1024 period delay. I 
think using 96 kb audio the delay is acceptable. Real hardware DSP's 
have a little delay too, it are also digital units.

gtx, Michiel.
