I've got a Tyros and Cubase SL 2 - they're not hooked up right now, but I'll try to help anyway.

Go to "Devices", select "Midi Device Manager", press "Install Device", select "Yamaha 9000 Pro".

Its not the Tyros, but they're almost identical in their sound format (besides the Megas).

You will now have the 9000 as a MIDI output. Whenever you want to select a sound for a certain chanel, instead of typing in a MIDI control number just scroll through the instrument bank in the "inspector".

What you say is happening should not be happening. Something is programmed wrong somewhere. Check in the MIDI section of your keyboard that everything is broadcasting into the right chanels. Make sure that on Cubase, each track is set to a different chanel. If you want to record multiple channels into one track of Cubase, select "ANY" as the chanel, and when you're finished recording select it and "Bounce" it. This should separate all the chanels into different tracks.

You have to remember as well, that the Cubase doesn't necessarily know which instrument your Tyros is using if it was never sent a bank and program number. Generally if you are using a style, the ty will not have sent those numbers. The reason it works for chanels 9 and 10 is because it is standard for those channels to be always used for drums and percussion.

Try recording one instrument on Cubase. Press record, let it go for a half a sec, then on your keyboard press the instrument you want to use (this should send the bank and program info), then play. When you play it back, it should be using the right sound.

Are you connected thru USB or MIDI? Also make sure you turn on the keyboard BEFORE you launch Cubase. Are you using a crack? That could be the problem as well...

Hope I'm of help,
Chony
