I'm using the USB out of the digital piano to my Lenovo Laptop (Windows 10) and then to a Topping 90SE DAC/Headphone amplifier using Sennheiser headphones. It works - but I do get some sound breaking up on some chords when played. Before going on - I also have a Focusrite 8-Pre that I've used for recording - but not currently using in the current set-up.
I've seen recommendations for use of an audio interface or separate sound module. I'd appreciate equipment recommendations that a new user wouldn't be overwhelmed by - though quality of sound is important. Budget is under $1k USD.
Save yourself $1k, use the Focusrite device you already have.
Maybe you don't need to use that anyway?
See if you are using "exclusive" or l"ow-latency" modes. ASIO or WASAPI - Windows audio.
Try running at 48khz. No need to go for a silly low buffer. See how you get on with about 20 milliseconds latency. It should not be necessary to get down to single figures as per recent forum threads where it was suggested in one report that a real pianos mechanical latency was about 30 milliseconds.
That 30 milliseconds number almost can't be right. I play lots of acoustic pianos and grands all the time and never feel any latency, yet if "digital" latency goes over 10ms I start to have trouble. I'm assuming that latency figure includes keyboard touch and hammer mechanism, don't forget most decent keyboards have some of that too. So you'd be adding the 20 ms latency to the 20/30ms whatever from the keyboard. The audio buffer latency is just that; it generally doesn't even include i/o latency which is at best another ms each way (ok only one way for purely digital instruments).
That said, yes use the Focusrite USB device you already have, if it has dedicated ASIO drivers.
At this point it's unclear what "sound breaking up" means and exactly what's causing it. It could be that you're clipping audio somewhere in the chain. If you still get this when plugging your headphones straight into the laptop and playing Pianoteq presets, it's unlike that that is the problem. If you DON'T get it when hooked up that way, then you're probably overloading the input of the Topping 90SE. You don't say how you've got stuff wired, I guess if you're using a DAC you're using an optical output on the laptop?
The "breaking up" could also be caused by your computer not being able to process all requests quickly enough. This would normally also be more present when you're asking more of it, e.g. playing chords is more demanding than playing a few single notes. You could see if changing the buffer settings has any effect, but you don't specify the sound driver (I suppose if you're using the internal soundcard, you're using ASIO4ALL?) or the connection type.
Most likely, if the latter is the case, it can be solved by using the dedicated Focusrite driver. I'd use the HP out from that and skip the Topping altogether. If you still have problems, run Latencymon while playing Pianoteq and see what it says when the sound breaks up.
