Got a bit of a problem with my new midi interface. On power up, the
midi interface gate LED is solid, and stays solid. After reading the A-
190 manual again, it says the gate, reset and clock LEDs lite up only
to midi activity.

Consequently, on power up a note is already being oscillated without
any keys pressed. As a key is pressed the pitch changes to the
corresponding note, and when the key is depressed, the note continues
to play/hang.

I would deeply appreciate any suggestions. Thank you in advance.
