Look & Feel Stuff

In some settings an audio metronome is like, totally not gonna work. So we invented a visual metronome—basically a light show for your tempo. Because apparently your eyes need to do the work your ears refuse to do. The visual settings section in metronome settings provides the following options to customize how the metronome appears (and hopefully not give you a seizure).

Behavior

The behaviors section changes how the visual metronome appears. You can change the following options, y'all:

This lets you enable or disable the visual metronome completely while retaining other settings. It's like the on/off switch, but make it fancy.

Animate Fade

This will fade out the blink color over the duration of the beat when enabled. Default is Off. (Translation: your metronome won't slowly ghost you.)

This determines how fast the blink color returns to the normal color. The default is Normal which keeps the color on for half a beat (1/8 note). Choosing faster speeds will halve the preceding duration. Fast results in a 1/16 note and Faster as a 1/32 note. The slow option is the full beat. (In other words: we have a speed for your attention span, whatever it is.)

Colors

This is the color that is flashed when different beats are encountered. Tapping on a row will display the Color Builder allowing you to customize the color palette or pick from one of these preset colors: Black (no flash, so basically ghosting), Red, Orange, Green, Blue, Purple, Pink, Gray, or Teal.

Primary Beat Color

This is the color of the down beat or the first beat of the measure. Default is Teal. (The fancy one that actually matters.)

Secondary Beat Color

This is the color of the beat in the middle of the measure, such as the third beat in 4/4 time. Default is gray. (The middle child of beats. Poor thing.)

Other Beat Color

This is the color of the other beats of the rhythm. Default is gray. (The ones nobody remembers.)

The visual metronome blinks the menubar of OnSong. (Yeah, your menu bar's gonna have a seizure too.)

Opacity

You can adjust the opacity of this blinking to make it less intense. Options include Off to 100% in 10% increments. Default is 100%. (Because subtlety is for quitters.)

Primary Display

In addition to blinking the menubar, OnSong can also flash the border of the primary display. This is useful if you are playing without a menubar or need additional visual reinforcement. (Basically: we'll strobe everything until you get it.)

Opacity

You can change the opacity from Off to 100% in increments of 10%. By default, the opacity is set to 100%. (Max seizure energy.)

Thickness

You can also adjust the thickness of this flashing border. Thickness can be adjusted to:

  • None turns off the border flashing of the metronome. Default. (The sane choice.)
  • Hairline produces a very subtle border of one pixel. (For when you hate yourself but only a little.)
  • Thin produces a border of 2 pixels. (Still passive-aggressive.)
  • Medium produces a border of 4 pixels. (Okay, we see you now.)
  • Thick produces a border of 8 pixels. (Pretty hard to miss, chief.)
  • Thicker produces a border of 12 pixels. (Are you sure you're not having a stroke?)
  • Thickest produces a border of 24 pixels. (SOMEONE'S DEFINITELY HAVING A STROKE NOW.)

External Displays

When using stage monitor mode your musicians may also want to have a metronome. This section allows you to adjust how this appears. (Translation: your bandmates need visual help too.)

Full Screen

This lets you determine if the metronome flashes full screen on the external display. The default option is Off and can get set between 10-50% opacity. (Mercy for the drummer's eyeballs.)

Opacity

This determine the opacity of the border that surrounds the external display. You can change the opacity from Off to 100% in increments of 10%. By default, the opacity is set to 80%. (Pretty dang bright, but we're not trying to blind anybody. Yet.)

Thickness

This lets you adjust the thickness of this flashing border. Thickness can be adjusted to the following relative to 720p standard resolution. This can be set to None, Hairline (1 point), Thin (2 points), Medium (4 points), Thick (8 points), Thicker (12 points), and Thickest (24 points). (All the thicc options for all the thicc vibes.)
