ROSSINI is the new KABUKI

This little piggy, thinks he deserves an upgrade. - The Prodigal Sounds, "The God Program"

ROSSINI is the name I have given to my new Digital Audio Workstation computer. It's a Dell Studio XPS 9000, with an i7-920 processor and 8 GB RAM running 64-bit Windows 7.

First, the good:

It's a great case, with plenty of room. I specifically ordered it with only one hard drive. My older DAW, KABUKI, has two hard drives: the OS and software lives on the primary disk, and the SONAR projects and music archive and related files reside on the second. My plan was to lift drive 2 out of KABUKI and install it as the second drive in ROSSINI. This plan worked perfectly.

There was one drawback (dawback?): I also transplanted the PCI audio interface (M-Audio Delta 66) from KABUKI into ROSSINI, but ROSSINI only has one PCI slot, and it is right at the edge of the motherboard, which means that the back panel - the metal strip with the connections on it - is located in the last available slot, right at the bottom of the tower case. The 15-pin D-connector couldn't actually be plugged in because the curved plastic base panel of the tower case overlapped too far, preventing the plug from aligning with the socket. 

You can sort of see where I'm talking about, in this picture from the Dell web site:

 

Not a problem: Set big-ass soldering iron to "imolate" and perform case mod. Now there is a nice (well, "scorched") cutaway in the plastic lip, just the right size for the D-connector.

 

One reason for the upgrade is because M-Audio finally came out with 64-bit drivers for the Delta-66 (and the other interface I use, the Midisport 2x2 USB). I love the Delta, it's been rock-solid under Windows XP in KABUKI for the last 5 or so years, so I didn't see the point in upgrading until I could go fully 64-bit.

A word about Windows 7. I'm only using it because I want 64-bit. Under Windows XP, even if I had maxed out the computer with 4 GB RAM, Cakewalk's SONAR could only access a maximum of 3.5 GB, and of course it is sharing the 4 GB with Windows itself. Under 64-bit windows, any 32-bit process can access a full 4 GB, if available. And of course, a 64-bit native application is not limited at all.

SONAR 8.5 is available in both 32-bit and 64-bit versions, but I am planning on sticking with the 32-bit version for now. I use a lot of 32-bit plugins - VST and DXi effects and synthesizers - that, although they would probably mostly work in 64-bit SONAR, would require a translation layer. I'm fine with the 32-bit version. A 4 GB memory limit is still more than twice what I was getting on KABUKI. In upgrading to ROSSINI, my sonar projects also have twice as many processor cores to abuse. (KABUKI was dual-core, ROSSINI's i7-920 has four cores - eight if you count hyper-threading which I'm not sure that I do).

So far, everthing is running O.K, although I suspect some kind of memory leak is going on, possibly in the audio driver. After about 30 minutes of working and recording takes, I get a nasty burst of digital noise every time I press RECORD and SONAR stops playback. Well, it keeps advancing along the time line as though it *was* playing back, but no sound is emitted. I'm still working on diagnosing this - there are a lot of places the problem could be stemming from.
