Because MIDI latency and jitter on modern computers is a problem. I've been contemplating in either get a dedicated hardware MIDI sequencer or an old Mac for MIDI sequencing, so I have some questions for you guys:

1) Would an old Mac perform just as good as any hardware MIDI sequencers?

2) Would a Macintosh Classic have enough power to properly sequence MIDI? (I already have an old one in the closet)

3) If so, what's a good MIDI software to go with it that it won't impose a lot of strain and cause latency and jitter that I'm trying to avoid?

Thanks!
