Unable to find device in config.

Rick:

That sounds very much like a driver conflict. If another program is trying to connect to the driver at the same time, you can run into the slowdown syndrome.

I have several Composer versions running on my computer, going back to 1.6 and they all seem to work fine with the UM-1. The version of Composer shouldn't matter at all; they're essentially the same when it comes to handling of midi ports.

The fact that you were able to send data to your synth means that the UM-1 port was working -- the fact that it was running so slowly points to a conflict. In the old days of DOS 3.0, I'd have said it was an IRQ conflict. Nowadays, it's either the driver or another program trying to access it at the same time.

Just had a thought: go to Setup/Midi Devices/Configuration/Port/Select Ports and see whether the UM-1 device shows up and whether it is checked as selected for your configuration.

Good luck.
