If you analyse the timing of famously 'tight' sequencers like the TR808 or
TB303, you'll find they have as much timing jitter as you would get latency
in a single MIDI note message - around 1ms.
So if you are triggering a 303 via a dedicated MIDI bus, your timing can be
absolutely as good as when using the internal sequencer.
When triggering drum machines, MIDI latency becomes more noticeable, because
you probably want to trigger more than one sound at the same time.
I find as you approach 5ms of latency, which amounts to about 7 MIDI notes
on the same channel with running status, you will hear percussive sounds
smearing against each other.
Personally, I use nearly all non-MIDI gear, but all with MIDI to CV
convertors.
I find the convenience of being able to route 3 or 4 CVs and a gate to each
synth with a single cable outweighs the 3 or 4 ms of latency I might get
from running 4 monosynths on the same MIDI bus.
