If you want to map the metronome to a button, you'll do these steps:
- In Layout mode, create a button and then assign it to your hardware by clicking the “Assign” button and then pressing the physical button while in the Layout mode. Make sure the type is set to “Single Value."
- In Edit mode, click that button you created- and then click “Map Parameter” so that, “Map Parameter” is red. Then click the metronome button to map the button to the metronome.
As long as the play button (green arrow button) is on, the button should require only one press to turn on/off the metronome. I would just leave the green play button on all the time. However, the beat may not start on the “beat one accent” so to fix that:
- Go to the concert level and choose the “Metronome” tab.
- Change the “Bar” note to match the “Beat” note. This way there is no accent on beat one. In other words, every beat could be beat one
Having this concert level mapping to the metronome is fine and it will not change the individual patch tempos, as the mapping is to the metronome and not the tempo.
If you are setting up an arp, here are some additional things to check:
- You will want MainStage’s green play button to be off (top right corner).
- In the “Keyboard” tab of the Arpeggiator, you will want to make sure “Input Snap” is set to “none.”
- To make the arp feel better (personal taste), go to the Arpeggiator’s “Options” tab and set the “Cycle Length” to “As Played”.
- Change the mode to be set to “Reset”.
Also note that there are some effects that will follow a background clock- even when the background clock is turned off, and this is a glitch. For example, the modulator seems to sync to the clock all the time, as does the LFO in EXS24. Thus, we have worked around these limitations in Sunday Keys to create effects like “Sidechain” via MainStage’s Auto Filter effect.
