Metronome - Metasound Patch for Unreal Engine 5
Compatible with Unreal Engine version 5.0 and above
I created this Metasound Patch to help me implement interactive and multi-layered music segments inside a Metasound Source Asset. My intention is to replicate some of the functionality from middleware like Wwise/Fmod (Pre-Entry, Trigger, and Beat/Bar Callbacks). Although this tool was created for music, I can see interesting applications for pure sound design, like triggering sample-accurate timed semi-automatic gunshots, for example.

IMPORTANT: To use this metasound patch, unzip and paste the “Metronome_Graph_Patch_V1” folder inside your project's “Content” folder. Finally, right-click on your metasound source and find the metronome under Graph/Patch.
Features:
Outputs:
On Pulse Start (Trigger): Triggers when the metronome starts.
On Bar Pulse (Trigger): Triggers on every bar.
On Beat Pulse (Trigger): Triggers on every beat.
On Pre-Entry (Trigger): Triggers before the loop ends using the (Loop Pre-Entry) value as an offset. If the value is 0.0 will trigger at the same time as (On Loop).
On Loop (Trigger): Triggers at the start of a new loop after completing a previous one.
On Stop (Trigger): Triggers when the metronome stops.
On Reset (Trigger): Triggers when the metronome resets. This trigger will wait until the next beat.
Current Bar Number (int32): Current bar number on the loop.
Current Beat Number (int32): Current beat number on the bar.
Pulse Audio Out (Audio): Metronome's audio output. Uncheck (Mute) to activate.
Inputs:
Start (Trigger): Starts the metronome. If (Start Delay) is > 0.0, this trigger will wait until that time is elapsed.
Stop (Trigger): Stops the metronome immediately.
Reset (Trigger): Resets the metronome counting.
Mute (bool): Mutes the audio output.
No Debug (bool): Stops debug messages on the output log.
Start Delay (Time): Time delay before the pulse starts.
Loop Pre-Entry (Time): Time offset to trigger (On Pre-Entry) before the end of a loop. This feature is useful when starting music segments that contain audio before bar 1.
BPM (float): Beats per minute.
Beats Per Bar (int32): Number of beats per bar.
Loop Bars (int32): Number of bars per loop.
Pulse Audio Volume Multiplier (float): Pulse Audio Volume Multiplier.
Pulse High Frequency (float): Audio frequency pulse for the first beat of each bar.
Pulse Low Frequency (float): Audio frequency pulse for the remaining beats of each bar.
Name (string): Metronome's name for debugging purposes.
