Is 4n33 optocoupler fast enough for MIDI?

I'm building Arduino based MIDI controller (this is my first MIDI project, initial planning phase).
To isolate synth I want to use optocoupler.
I have some 4n33 optocouplers already, would they be fast enough to send serial data to MIDI port? From datasheet turn-on time is 10uS and off is 100uS. I know that MIDI baud rate is 31250. Should it work?

I have used a similar part with success.
If you add a resistor from the Base, pin 6 to Emitter pin 5 you can tune the o/ p waveform.
I think the value would be between 100k and 200k but you will have to do your own experimenting and look at the o/p with a scope.

Perfect! Thanks a lot LarryD!
