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

After reading all the other posts, I tried serially reinstalling OMS and the Yamaha drivers, restarting both keyboard and computer. No luck.

Then after I took the keyboard to a local music store and had the guy try to link another midi keyboard to it (which worked) the light went on -- the cable to the interface is labled MIDI IN but it hooks to the MIDI OUT port of the keyboard, just like another keyboard's MIDI IN comes from the MIDI OUT of this box. (I thought I had tried that, but I guess not. )

Once I saw it in terms of labels FROM another MIDI device I was fine. DUH! (But it's not exactly intuitive to attach IN to OUT, is it?)

Just wanted to clear this up.

Glad you figured it out

The obvious isn't always obvious - like bank statements are extracts of their accounts with us, not our accounts with them (or is it the contrary?). Debit should be credit and credit should be debit in our books.

Hope you understand that
