Ye, after browsing in the Song forum i got this crappy behaviour.
1.) I download a Renoise Track and doubleclick on that.
2.) Renoise gets started, and plays the track. So far so good.
3.) I download another Renoise track.
4.) A 2nd Instance Starts up and then Renoise brings up this pop-up:
5.)after clicking on the OK button, the first Renoise starting like crazy and the Sound is been playing like freezed.
6.) So i have to close the 1st Instance, to hear the track on the 2nd instance.
7.) After checking Renoise’s Audio Device it has been reseted to DirectSound, so i have to switch it manually back to ASIO
