Latency And Recording Audio Questions Options

[tom2323]

Just wondering if anyone can help. got a g4 imac with logic 4.8, recently bought an edirol UA-20 audiointerface, there's a bit of a time delay, think i should do something with the latency.whats the best settings considering my equiptment (for guitar and turntables into logic). also is it possible to record for longer than 50 mins of audio into logic? cheers. tom.
