Freezes the frames in sequence across the screen. Good to synchronize with BPM in resolume.
This is only the protocol FFGL version. To use it only as a composition you would need to replace the parameter "MapThis" with a "curve" command. You may want to add other curves for the other parameters to get the most of it.
If you're using it in Resolume you can quickly add BPM syncs and envelopes to the parameters to get some cool effects. It also produces some unintentional but interesting glitches if you don't let the main parameter return to zero.
