Troubleshooting Sunday Keys for Ableton

If you are having trouble with Sunday Keys for Ableton, check out the Troubleshooting videos over at our Sunday Keys for Ableton Resource Page as well as these things:

• Turn off IAC Driver. If you need to use it, open Ableton Midi preferences and turn “Track” “Sync” and “Remote” off for both input and output for all his IAC instances in Ableton Midi Preferences. Then you should be able to turn on IAC and then turn back on ONLY the exact midi preferences you need on for IAC. There may be extra, unnecessary settings currently turned on that Ableton is listening to, which is causing the freeze up.
• Adjust buffer size - as long as latency isn’t bad, 512 should be fine. You'll want to just test this out on your machine.
• Trim down the Set as you feel the need by removing instruments from the "Instruments Go Here" racks present on each track, just keep in mind that you'll be affecting the layered worship patches as you do.
• Try loading the template from inside a blank Ableton Live set, so that Live is already open first.

It is strongly recommended that you have 16 GB of RAM to open Sunday Keys for Ableton. If you have a Mac 2013 and older, you may have issues with Sunday Keys for Ableton 2. Some users on older/less powerful systems may not be able to open Sunday Keys for Ableton with only 8 GB of RAM. Users with newer systems and more powerful GPUs and processors should be alright with 8 GB RAM.

If you are having an issue with the mod wheel having a CPU spike, this is due to an unfortunate default in Ableton Live that passes midi CC data through to all instruments open in a Set, even when they're inactivated via Chain Selector (as all the bypassed instruments in Sunday Keys are). This is also why a sustain pedal press can cause some CPU peaks as well. For that we recommend adjusting your audio buffer settings where possible to reduce the likelihood of the issue. 

Regarding the mod wheel, we generally just discourage using it as a part of your rig for this reason. We hope Live will eventually allow folks more flexibility over how midi is passed thru or filtered by a given instrument but until then there are some of these unfortunate constraints inherent to the program.
