capella playAlong generates its own sounds:
On-board sound cards are renowned for delivering poor quality. capella playAlong generates sound files using its own conversion system, which makes them completely independent of the sound card and is guaranteed to sound much better.
High-end: capella playAlong supports the capella Vienna orchestra, our matchless sound library. Every sound you hear has been recorded by a real-life musician.
With its VST and DXi interface capella playAlong is able to access other suppliers' sound libraries.
