Just use the Freeze parameters dialog box to make your settings the default settings.

You adjust the key release noise and also pedal noise too.

Just for test put the pedal noise in maximun and you will heard a interesting effect.

That's key release noise. You can find it in the "Action" panel.

Hi, please could you hear this example ?

https://www.box.com/s/fz9lczizd07jc12xgnu0

You can notice the "final sound" at the end of the pressed keys...

This doesn't occur with previous version of Pianoteq (4.2.1), the settings are the same, I'm using 64 samples (1.5 ms) of Audio Buffer Size.

I didn't understand how to eliminate this "release sound" with this new 4.5.1 version of Pianoteq, is this a bug ?

Actually, Julien, with WASAPI I am getting quite low latency on both my laptop and my desktop (easily between 128-256 samples). It is very playable. It totally depends on computer configuration, it seems. However, WASAPI is definitely not the same as DirectSound - WASAPI is basically Microsoft's version of OSX CoreAudio.

Hi, I own an iMac and me too have recently upgrade to 4.5 (from 4.2.1), my version of pianoteq is stage.

I hear in this version a strange "release" sound when relasing the key, this didn't occur with the previous version, I've recorded an example (in wav exported from pianoteq), how can I upload it ?

This is expected, "DirectSound", and even "Windows Audio" (also known as "Wasapi") are not suitable for realtime sound production, they impose a latency that is too high. You can use them for playing midi files, or when you need to share the soundcard with other applications, but they should not be used when playing on a midi keyboard.

I've upgraded to 4,5, but I've noticed that there is lag when using Direct Sound in the 'Audio device type'. This was solved though by selecting Windows Audio or ASIO. Has anyone else experienced this?
I'm using Windows 7.
