Hi Bernier,

Which version of PowerTracks are you using?

Let's go to Options - Preferences - MIDI - MIDI Devices. What's selected as the Output Driver? Is "Re-Route MIDI Playback to default DXi/VSTi Synth" checked? If so, what's selected as the Default DXi/VSTi Synth.

Let's click OK, then select the Audio tab in Preferences.

What do you have selected as your Audio driver type?

Thanks
Kent
