The "Windows Audio" output option uses the soundcard in shared mode. This will incur a latency penalty no matter what buffer size you set in Pianoteq.

Hi, thanks for the feedback. The problem is, even with the lowest buffer with asio4all (i get 1.5 ms) i can't hear any latency improvement compare to windows audio 4ms. My audio is intel sst.

Is there still anything i can do?

A person on the web said he can't get his Asus Transformer Book T100 (similar spec with this HP) to run pianoteq. But I took my change, after tweaking for 3 hours finally it run pretty well with the on-board audio. Here are what I did:

- Change the processor minimum state to 100%. If you don't have the option don't worry, some manufacturer hide this option, just follow the instruction in the following link to edit the registry :

- With this HP, I got no success using Asio4all since the volume become very low. But using Windows Audio option, I can choose the lowest option, 192 sample (4ms), which should feel pretty nice to play.

- My Keyboard is Casio PX 150, so I set pianoteq to receive MIDI high resolution.

- The most stable max polyphony is 32, although you might get a good result with 48

- The performance index shows 15

That's all. I still can feel a slight latency compared to the casio internal sound, however I can't find any solution for this. Is there anybody can give a clue?
