Elektron Musical Instruments

Hi all. I have a MD and was thinking in getting a sidstation, but I 
read on harmony central the sid has latency. Is this true? I ask 
because I plan on using it live, and the latency would be a turn off.

I have searched everywhere but cant find any info about it. Could 
someone help me? Just a yes or no, and if its really bothering.

Thanks in advance
