Been using Mixcraft 6 and an Alesis io4 audio interface for a while and have noticed that as soon as I have more than around three tracks recorded (eg. vocals, guitar, drums and bass) when I play back the whole recording on mixcraft or attempt to record more over it the track lags and skips making it difficult to record anything over it. Don't think my laptop has a sound card. Is the problem that my computer can't handle this much audio and software? I study English...so this is not my area of expertise lol Any help would be appreciated and please feel free to dumb it down!!!
