Bridging the 64 bit Gap with jBridge

Bridging the 64-bit Gap with jBridge - Home Music Production

Increasingly the sample libraries we love require more and more RAM.  A few sampled libraries now require upwards of 1 Gig of RAM to play a single sound patch or program.  Although this is fantastic for maximizing realism in virtual instruments, the need for running a true 64-bit DAW environment becomes increasingly more important.


Having a 64-bit chain from the operating system to DAW (Digital Audio Workstation) will allow you to access more than 3 Gigs of RAM from your DAW.  Some popular DAWs such as Pro Tools LE / M-Powered, Digital Performer, and Ableton Live are still 32-bit as of this writing.  Cubase 5, Sonar 8 and Logic Pro come with both 32-bit and 64-bit versions.   All of these DAWs will work on a 64-bit OS, however only a true 64-bit DAW will be able to address more than 3 Gigs of RAM.

The challenge with using the 64-bit version of your DAW is that a few plug-in developers haven’t yet updated their software to run in a 64-bit DAW.  To combat this, the 64-bit versions of Cubase and Sonar use a 32-bit to 64-bit bridge such as VST Bridge (Cubase) and BitBridge (Sonar).  However these built-in bridges don’t work so well with all plug-ins, so if you’re like many Cubase users, you’re using the 32-bit version of Cubase inside your 64-bit Windows OS.


Enter jBridge.  jBridge is a program that allows you to bridge a 32-bit VST plug-in with a 64-bit DAW, or bridge a 64-bit plug-in with a 32-bit DAW.  Currently jBridge only works with VST plug-ins.  The cost is about $21.19, but getting access to all your RAM is priceless.

jBridge 1.2 comes with a jBridger tool which takes the 32-bit plug-in you’re looking to bridge and creates a 64-bit wrapper allowing the wrapped plug-in to utilize more than 4 Gigs of RAM.  In the reverse scenario, bridging a 64-bit plug-in to a 32-bit DAW, such as Ableton Live, allows you to utilize any plug-ins that are exclusively 64-bit.  Also in the latter scenario it will allow you to overcome the limitations of a single 32-bit process.

So for any of you who have more than 4 Gigs of RAM on your computer and are running a 64-bit OS, and specifically to any Cubase users out there who are using 32-bit Cubase in a 64-bit OS like I was, give jBridge a try.  Since most of my plug-ins are now 64-bit, I only have a few 32-bit plug-ins such as my Music Lab guitars and Addictive Drums, and jBridge works perfectly.
