Topic: Pianoteq and Raspberry Pi USB audio output to Yamaha DP

I am considering buying a Yamaha DP with built in USB audio interface such as the P515, CLP series, etc. I would like to play Pianoteq over the piano’s internal speakers.

For those of you who use Pianoteq on Raspberry Pi, are you able to send USB audio from the Pi directly to the piano? It seems that you need to install the Yamaha Steinberg drivers to make Windows PCs send USB audio to the piano, but those drivers are unavailable for Pi as far as I know. But perhaps they aren’t needed.

Thanks!

Depends on Yamaha if they made their USB-Audiointerface being USB class compliant. Then it can be used platform independent with every Linux PC (Raspberry Pi is one), Mac and others.

Linux has the driver/kernelmodule snd-usb-audio onboard, that supports all USB class compliant audiointerfaces. For example my Korg B2 is USB "plug&play" with a RasPi at 24bit/48kHz.

This mostly works. I have a Yamaha P-121 (73 key version of the P-125), and Pianoteq on the Raspberry Pi 4B. I can select this in Pianoteq as my soundcard, and get Pianoteq's audio output through the Yamaha speakers.

The only problem is that there are random audio glitches (for lack of a better word) - brief crackles or pops. This NEVER happens using the Raspberry Pi's soundcard (IQaudIO). It also never happens using a different USB audio interface (ART USB Mix4). So I'm guessing it is a limitation of the Yamaha USB audio interface.
