[sdiy] MIDI optocouplers

> What optocouplers do you use for MIDI?

For time critical design (like in my MIDI-Matrix) I use the HPCL2631 from 
Hewlett Packard that is designed for 10Mbit. In the datasheet a load resistor
of 4kOhms is defined in the diagrams. And the performance with this load 
resistor is OK.

datasheet can be loaded from here:
