No sound card will help when you're outside the recommended range of the RTs. I've found that often even the outer range gives undesirable sounds. If you must stretch, try to stretch upwards and not downwards. Example at 125, you may find that a 110 RT sounds better than a 140. If you can get the track sounding fine at the recommended tempo, probably nothing is wrong with your soundcard. I don't think ASIO would help in your case unless you're doing some real time recording with an external instrument.

A piano has a very complex sound structure which is probably why you're having problems with it. I don't use the piano RTs because I play keys but have had luck stretching with the Acoustic bass RT.
