MainStage's Vintage Organ like you've never heard it before.

There's no need to purchase any additional sounds or plugins. All of the sounds in the Ultimate Organs pack use only MainStage's built in plugins, but take them to new heights. Every sound is layered in rotary cabinets, filters, and compressors, all tweaked for stability live. It's even possible to switch between various reverbs, delays, and even spring reverb using just the on-screen midi controls. 

Vintage vibes without the constant repairs. 

We've made over 150 CPU-friendly tweaks for this pack, then stress-tested every patch on stage and in studio. We included CPU savers like automatic plugin bypassing, buss routing for common FX on every channel, and volume-leveling tweaks at both the patch and concert level. 

Studio-quality sound, meet stage ready control.

The Ultimate Organ Pack is Nashville Standard compatible, which means that every knob, button, and fader on your midi keyboard will have a thoughtfully mapped, color-coded on screen control.* No more fumbling to find the right knob. Just download the pre-built free template that matches your controller, drag and drop your patches, and start jamming.

“Patch Foundry has done a fantastic job with these patches! They are definitely good enough to use live or in the studio. They sound as good as samples that are much more expensive. Two thumbs way up!"
