Re: crystal change

I did a little test. Out of curiosity, I recorded my GSP2101 to my 
computer using Cakewalk, with the effects send going to one track and 
the right output (with the wet/dry mix set to 100% dry) going to the 
other track. When I analyzed the wave data, the right output was 
around 6-7 ms delayed compared to the effects send. Since sound 
travels at around 1 foot per second, it should sort of sound like 
playing 6 feet (2 metres) farther from you're speakers. My 2101 is 
still at 10MHz though. I don't know if going to 20MHz would make a 
difference here.
