I had purchased a Roland SD-20 device some years back. It appears this device is becoming obsolete. that is, being replaced by software like Sound Canvas va.

My question - My original purpose for buying the SD20 was just to make music played from BIAB sound better. Do I really need to do that? That is, is the sound just native from a new MacBook OK?

If I want to do the same thing as I did with the SD20, should I get the Sound Canvas va at $120, or is there an alternative? Roland does not provide updated drivers for the SD20 beyond Mac OS 10.9 or so. Although, it was suggested I could get this interface and still use the SD20

I just want to play tunes through BIAB and have it sound decent.

Appreciate any guidance.
