Another alternative is Sonar Home Studio. It is a slightly limited version of Sonar marketed to consumers. Since the product was based on the Sonar platform it is available as either 32 or 64 bits. The product was not part of the update every month program so it was very stable from its initial release. It received one update and that was about two weeks prior to the door closing.
The installer was updated to allow the use of unlimited audio tracks. The update also has some stability fixes that didn't make it to the rest of the Sonar product line prior to the shutdown. The download is the latest build.
Sonar Home Studio requires installation by the Cakewalk Command Center so you must have an existing Cakewalk account.
There is also an option to download and install a little more than 1 GB of audio sample loops from various Big Fish Audio sample packs.
