#HOW TO USE YAMAHA USB MIDI DRIVER MANUAL#

If there is not an audio cable connected to your keyboard, that suggests that you are controlling another source of audio (a softsynth in Sonar or freestanding in your computer, a synthesizer built in to your sound card etc.), and that your keyboard is changing patches in that remote synth when you change the voice on your keyboard. Is there an audio cable connected to your keyboard at all? Then how does the audio signal get to the speakers? Most likely you are sending MIDI via USB to Sonar that is then sending MIDI via USB back to the keyboard (triggering keyboard voices), which in turn is sending audio via an audio cable somewhere (to a Sonar audio track echoed out to your sound card, looped back through your sound card mixer (or via a real-time monitoring feature) to your sound card output, direct to your speakers). However, audio dataĬannot be transmitted or received via USB on the S90 ES.' MIDI messages can be transferred between the sequencer software and S90 ES using the USB cable.

Let us assume that the manual is not wrong when it says: What it's NOT doing right now is responding to soft synths, and I'm sure it's because I don't have something configured right somewhere. If I change to a different voice on the keyboard, it shows up through the computer, back out through the audio interface and on to the speakers. I don't know about what it's actually supposed to do or not supposed to do, but I have it transmitting audio over USB at this very moment.
