As is typical, the output high current is very low and needs a strong pull-up. Also the whole data sheet uses 270 ohm pull-up for all measurements and it is likely that 4k7 pull-up is too high. In theory you would use a better and more suitable optoisolator for MIDI. For prototyping and one-off hobby purposes, it may work in a controlled environment. For example, MIDI has quite strict skew limit to keep a chain of devices working. | |
