Nothing to say the installation, without worries.

SUITABILITY/PERFORMANCE

Stable, no bugs, robust, reactive, short ... Nickel

OVERALL OPINION

Accustomed to Acid Pro, I very well hung with Studio One. Really great app.
I could adopt but unfortunately .... Can not adjust the Windows volume, you must leave it to Studio One .... It's really stupid. Moreover reaper suffers the same problem.
If someone finds a solution (without a workaround for the hard huh ...) I could re-evaluate my note ...

And if so, I tried a lot of multitrack, my preferred solution remains Record / Reason.
