Jean-Guy,
1. Choose the VSC-DXi synth (Options-MIDI Drivers dialog, select Use DXi synth, and then chose VSC DXi).
Then exit the dialog, play a song, and it should work. You can turn VSC DXi off then (by simply de-selecting the checkbox, dont revisit the DXi dialog)

If that doesn't work, 2. disable Prefs-RealTracks-Speedup RealTracks.

JcLand,
Same advice would apply (select DXi synth), but your message states "the programs works fine" and "build 295 does not fix". Not sure which is applicable (esp. since the latest build is 292), but if you do the step above, it should work fine. Dont disable the audio plugins, if you do, you are defeating the fix that appeared in 292 - and would need to do the steps above (VSC Dxi synth).


Have Fun!
