Psr 280 Won't Talk To G4, Connections/interface problems Options

[GeorgeMack]

Just received the UX16 midi to USB interface kit to hook my PSR 280 to my Mac G4, and can't seem to get it to work right. (After 7 months on backorder, I'm a little disappointed, you might say.)

On the Mac, (OS ver. 9.2.2, and 256 RAM, 15G disk space) the OMS setup finds the USB cable/interface box, but nothing passes to or from the keyboard. (Clicking the "test" note on the diagram in OMS Setup flashes the green MIDI light on the UX16, but the piano does nothing.)

I downloaded the latest version OMS (2.3.8) but that didn't help. I also tried a bunch of sequences of what turns on first, etc. and still no chirp of any kind from the keyboard, although it works great as a stand-alone keyboard. Also tried a bunch of the "Hold down highest/lowest key and turn on keyboard" stuff mentioned in the Yamaha manual, and still no connection.

The Mac 1.05 version of the Yamaha USB Midi driver came through garbled and wouldn't launch after unstuffing (3 times) so I've got version 1.02 that came with the interface.

I'm using is MusicTime 3.0x by GVox (formerly Passport); but the demo version of Finale 2001 (Coda) and a utility called SysEx452 also failed to find the keyboard.

Yamaha SongFiler says to check that instrument is properly connected (Yep, all cables are properly connected...) including a "host select switch". Is there such a thing on the PSR-280? It's not shown in the manual or visible on the keyboard.

Notes don't seem to make it to or from the keyboard, but OMS thinks it sees the cable on the Mac end. Did I miss something?

Thanks for any help you can offer,

George
