Topic: AUDIO USB MIDI to DIGITAL PIANO with SPEAKERS

Hello to all Pianoteq funs!!!
I connect my laptop straight to my digital pianos (Yamaha CSP-170 or Thomann SP-120, both have USB audio technology) with one USB cable only. In Pianoteq's menu, I choose the correct drivers (steinberg asio for the CSP-170 and any Microsoft for the SP-120), and then I choose the piano's speakers to export sound. And this works perfect as a connection. With just one laptop and one USB cable!!! Of course the Yamaha's 180 watt HQ speaker system is way better than the poor 40 watt of the Thomann's portable piano. But there is something strange: When I connect my headphones to my pianos and play fast, the sound is getting poor and a bit messed up (more in the Thomann than in Yamaha). When I change drivers / settings and I connect the headphones straight to my laptop, the quality is perfect no matter how fast I play. Is there any explanation about this? I think that, maybe the USB send only data and the piano's DAC is decoding and drops the quality of the sound... is this what is happening? (I use the speakers on this test to understand better the quality of the sound. I guess the same happens to both piano speakers, but I can't understand so well the sound quality drop).

make sure you have disabled "local control"... otherwise you will get sound from the VST and your piano at same time!
disabled "local control" will disable the sound of your digital piano, you will only hear the VST sound

Yes, of course. I do that. But it is something else. If the PC send the digital signal to the DAC of my piano (through the USB), then the piano's DAC can't do the job as good as the pc. Is my thought right?

Re: AUDIO USB MIDI to DIGITAL PIANO with SPEAKERS

Did I get you right, you have no issues with speakers, only when using headphones?

I'm confused, that your issue only appears when you're playing fast...
I assumed, that you always been hearing your digital piano and the VST... With headphones, you can hear this of course more clearly and it sounds messed up.

Your piano maybe could not drive your headphones well...
But this issue should appear always, not only when playing fast...

What headphones are you using? What impedance do they have?
