I have been thinking, in your experience what is the most reliable
platform/set-up to run csound (with blue). I'm not using csound for live
performance but I would like to have the ability to audition instruments
live as I'm composing, without getting glitches or freezes. Right now after
about 40-50 instances of an instrument that uses oscil3 x 2 (also used for
envelope control) and pretty large tables for good resolution (on csound64,
osx, powerbook pro) I get nasty glitches and have to increase buffer size up
to 4096 or more. There is no way of decreasing the number of notes as I'm
using the score for additive synthesis. Of course I understand that I'm
being demanding and again I'm not looking for realtime stability on stage,
but is there a better set-up/platform that can handle this? What is a good
buffer size setting on an osx intel laptop (I have 1GB RAM)? 

Has someone done a test as to how much RAM and what set-up is needed for x
number of high precision oscillators to run smoothly on different platforms?     

Thanks
Peiman

you could try logging in as ">console". i have not tried this but have heard
that it works with some versions of OSX.  if you only need the command line
for what you are doing this should give you more resources. 
later.

Hi

I tried this once but the problem is that it doesn't support any  
graphics at all. So I won't be able to run blue or even a text editor  
(as far as I know anyway). I'm just downloading this:
http://code.goto10.org/projects/puredyne/

Looks very very exiting!! You can run it from  USB key as well which  
if it works will be awesome. Next have to see if blue is installable  
on it!

Best

Thanks Steven,

In fact most of my problem is solved by using the freeze option in blue!
Ones happy with something I simply convert it to poly and freeze it, then I
can start adding other layers... Great feature!
