Jan,
    Thanks for keeping it in mind for the future.

    This sort of stuff goes a long way toward driving you crazy. If you 
play with Waves PAZ then you get used to stereo phase meters, peak/hold 
stuff, all the goodies.

    While I'm sure not everyone can handle the CPU load, on my 3GHz 
laptop Jamin is only running about 25% load when playing my wave files 
using alsaplayer. I'd still need to add in a 2-channel HDD recorder to 
write the output of Jamin (will you make a recommedation?) but that 
won't take much CPU. Anyway, I can probably afford the extra cycles.

    Hey - why don't you add all this stuff anyway, upset everyone that 
who's machines aren't fast enough, cause them to buy new machines and 
then take credit for the improved economy? Do it before or after the 
election if you have a certain political leaning! ;-)

Thanks!
