Frequently Asked Questions

What is included in Sunday Keys?

Sunday Keys MainStage Template

The foundation of your worship keys rig! Sunday Keys makes it easy to sound amazing with our collection of worship sounds.

Find Just the Right Sound, Fast with Intuitive Preset Browsing

Quickly sort and filter the massive list of hundreds of different go-to keys sounds by instrument type and common descriptors like bright, shimmery, ambient, etc. We’ve made it easy for you or your keys volunteers to find the perfect sound.

Build the Exact Sounds You Need, with Patch Builder

Patch Builder in Sunday Keys lets you created a custom layered worship patch by quickly combining any of the hundreds of individual sounds available in Sunday Keys. Whether you’re trying to nail a specific song or assemble a go-to patch that can cover your entire setlist, building the perfect sound will take a few minutes instead of a few hours, all because of Patch Builder.

Nail Every Transition, with the Tonic Pad Generator

Tonic generates an ambient drone pad in the key of your choice in real time, at the touch of a button. The Tonic Pad Generator includes controls for shaping the tone and character of the eight selectable drone presets so you can glue together your live band and nail any transition between keys or songs.

We’ve Made MainStage Simple to Set-up

Sunday Keys features a drag and drop installer and high quality video tutorials to walk you through everything you need to know to get playing with Sunday Keys in minutes! You’ll also have access to more advanced tutorials when you are ready to take your keys skills to the next level.

What kind of computer and gear do I need?

You’ll need a Mac computer capable of running MainStage 3.4.3 or newer.

IMPORTANT** At this time we cannot recommend the recently released MainStage 3.5 build. While it is possible to open Sunday Keys in MainStage 3.5, we recommend sticking with MainStage 3.4 until MainStage 3.5 has been available for several months as by that time we will know how reliable it is for live performances.

The recommended MacOS Version is Mojave or newer. Please ensure all the hardware you desire to use is compatible with the OS version you plan to use. 

8 GB of RAM or higher is recommended and 4.4 GB of hard drive space is required for installation.  
If your keyboard or controller can send midi data you can use it as a controller for Sunday Keys! Details on connecting your controller to Sunday Keys are included in the video documentation you’re given when you purchase Sunday Keys. 

Sunday Keys does NOT require any third party plugins or instruments. Everything you hear in the audio demos uses only the included custom sampled sounds along with 100% stock MainStage plugins, effects, and processing.   
Have a plugin or instrument you love? You can easily add it to your Sunday Keys rig. Your download includes video documentation that will teach you how.

Sunday Keys come pre-assigned to the Korg nanoKontrol2 midi controller and the TouchOSC smartphone/tablet app. While you can use any midi controller you’d like with Sunday Keys, the nanoKontrol2 and TouchOSC are both great ways to control Sunday Keys live.  

What If I'm not very tech savvy?

Thousands of ‘less than tech savvy’ users love Sunday Keys!

Setup starts with an ultra simple installation process that happens automatically then at the end of installation you’ll be taken to a page of easy video tutorials that walk you through opening Sunday Keys for the first time, connecting your keyboard and computer audio, and everything else you’ll ever need to know to get the results you’re looking for.

And if you can’t solve a problem on your own, our customer support team will be standing by to assist you with dedicated email support.
