Hi Purple !
I have to admit : I AGREE WITH YOU
I am both musician and DJ since I was 10 .. I am 34 now ... yeah 24 years of music ! So I think I can say I have some experience
1. Difference of sound between Live and the other progs ...
My test : just listening to one of my track in SX 2 and then Live.
With Live I loose a bit of spacial effect. I dont care about bits and
tests and 0010101 for testing. I just use my ears. I was so impressed by
that so I ask my wife to hear the same track 2 times and to tell me
if there is a difference between the 2 ... She prefers the track from
SX which was indeed the same track but running through 2 different
appli ..
Maybe the reason is that Live is making a conversion from the original
bits (16 in my case) to 32 and then back to 16 ...
The question (and I will do the test). Is SX adding some artefacts that makes the wav sounds better ? I read on a forum that SX was adding
some hidden EQ (for bass and trebble) ??? I should compare to the CD linked digitally to the PC ...
For me it is not a blocking point of using Live but I not use it to create my new songs ... just to perform them live. We are not loosing too much quality ... I dont think that these differences will make people stop dancing
For your info I have been performing DJ sets with Live with no probs and people were crazy ... so that "loss" of quality is really not too much important
2. The crowd in clubs
I agree that sound is important to the way people react. But as said before minor loss wont change the way ... What I can say is that with
mp3 (here we can talk about major loss

it is another debate !
For the joke I remember a set of DJ with Final Scratch and his mp3 were
encoded at 128 .. believe me or not but the sound was really missing something and the final result was that people stopped dancing. It was not a thing about volume ... more about definition of bass .. His tracks were good but people were waiting and they were dancing with the previous DJ (yes he was with vynils
In conclusion stay cool .. this "bug" is not too much important and you have got so many other features with live that it is a minor point ...
Last exp joke :
I have exactly the same problem about guitar
I play a set of Marshall with racks. The sound is excellent but when I have
a concert I have to rent a big car (to put everything inside) So I decided to buy a Boss GT-6 ... I spend days and nights to twick that effect and the result is near the "original" set but something is still missing ... I dont like that but when I will be playing large arenas I will have roadies to bring the marshall stuff

It is quite the same problem ... having to balance the + and the - and take decisions ..
Sorry I didnt wanted to be so long ... This thread took me so much time to read ... so yes now it is your turn
bye
