Re: Laptops and Latency...



Latency is a very serious issue with both laptops and hardware 
loopers. I had to modify my Electro-Harmonix 16 second delay re-issue 
so that the "Dry" signal path was only passing through the analog 
circuitry, the latency was just maddening... The Electrix Repeater 
has a tremendous amount of latency in the "Dry Path",  so I built a 
little mixer to pass the input signal and every time I power up the 
Repeater, I need to remember to press the key combination which mutes 
the dry signal path.

I know that there are a number of interfaces which allow direct 
monitoring for zero latency, such as the Tascam 122, but if you 
expect to use anything in the computer to process the 'dry' signal, 
you will experience latency...
