OSC being lossless has not been my experience. The problem I have had is
the OSC messages are generally one message per packet which means that a
large group of messages can overwhelm udp quite easily. OSC does allow for
using bundles of messages to be performed at the same time, however MIDI
to OSC cannot really determine a group of events that happen at the same
time because of it's (slow) serial nature.
Do note that the osc message "stormes" I have had trouble with are bigger
than what MIDI was designed to handle in realtime (10 events from 10
fingers). I am talking about refreshing a control surface with at least 8
strips with each strip having 20 or so events. So well over 100 events.
When I tried to use bundles, I found that no control surfaces created or
understood bundled messages. I ended up adding a small delay in the sends
to fix this... not very "real time" :) Not noticable while moving one
control like a fader but noticable if performing music.
