MainStage's built-in plugins like you've never heard them before.

There's no need to purchase any additional sounds or plugins. All of the sounds in the Ultimate Electric Pianos pack use only MainStage's built in plugins, but take them to new heights. Every sound is layered in amp modelers, filters, and compressors, all tweaked for stability live. It's even possible to switch between various amps 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 Electric Pianos 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 masterful job of taking the stock sounds that come with Mainstage, and creating very musical, inspiring sounds.  The “bang for the buck”, as they say, is inspiring for your wallet as well.”
