One of the few limitations of the PSR-E473 compared to higher-end workstations (like the MODX or PSR-S series) is that it does not function as a native USB Audio Interface. This means you cannot simply select "PSR-E473" as an audio input device in your DAW to record the keyboard's live sound digitally via USB.
To achieve that "Extra Quality" audio recording of the E473’s internal sounds, you must use the Analog Outputs.
The Pro Setup for Maximum Fidelity:
This method bypasses the onboard speakers and sends the raw, processed signal from the E473’s tone generator directly to your computer, resulting in a studio-quality recording.
If you feel your keyboard sounds "digital" or "crackly" through your computer, the issue is rarely the keyboard itself—it is usually buffer size settings related to the driver or interface. yamaha psr e473 usb driver extra quality
The Buffer Size Dilemma:
The Solution: If you are using the Yamaha USB-MIDI driver to trigger virtual instruments, adjust the buffer size in your DAW settings. A setting of 256 samples is a great balance for the PSR-E473, offering low latency without audio dropouts.
While the keyboard is "plug-and-play," serious musicians should install the official Yamaha USB-MIDI Driver rather than relying on the generic Microsoft driver.
Why this creates "Extra Quality":
How to install:
The Yamaha PSR-E473 connects to a computer via USB to transmit MIDI data (not audio).
The official USB-MIDI driver allows:
This is the most critical setting for quality vs. performance.
To summarize, if you want the highest possible audio fidelity from your Yamaha PSR-E473 via USB: One of the few limitations of the PSR-E473
By following this guide, you transform the PSR-E473 from a standard keyboard into a professional-grade audio interface suitable for studio-quality recording.
Generic Windows drivers (MS GS Wavetable Synth) are designed for basic playback—think YouTube videos or system sounds. They are not optimized for the real-time MIDI data or 2-channel audio streaming the PSR E473 offers. This results in:
