To put it simple I have a computer with what I think would be good specs ( 64 bit, 16G ram hex core 3.3 GHz processor) and an m-audio fast track pro going into Reaper 64 bit. The problem is I have only 4 tracks so far being superior , two rhythm channels (all vst effects amp Sims, etc) and a bass with no more than 20 seconds recorded/programmed. When my guitar is through record monitoring (the only way I can hear my guitar with the effects and amp Sims on) it starts to glitch and crackle/pop. Does anyone have any suggestions or solutions ? I thought upgrading from a shitty laptop would let me record and mix at lower latencies so maybe its the interface? I dont see why.... it seems like a decent interface.
