We are having problems with our Midi on an iBook. It worked for a year and half sith Soundiver but now doesn't work anymore.

I downloaded Midi Test to see if Midi is working ok and the laptop. When we click on the keyboard in the application it will send midi signals to the Roland TD10 module and play the sounds. But when we run the sequencer on the TD-10 we don't see anything happening in MIDI Test.

What are all of the buttons on the interface? Shouldn't the MIDI Receive light up when a signal is coming into the computer? How does this app work?

Reconfigure OMS, trash its preferences.

If it doesn't work. Trash OMS and the driver of the interface, along with their preferences and reinstall first OMS then the driver.

I have trashed and reconfigured OMS several times, I will try again tomorrow.

But would you please tell me more aboout how to use MIDI Test? What do all of the button mean?
