Event Modifying Effects

Event Modifying Effects

MIDI effects in this category do not create any new MIDI events, but modify them in some way.

Compress

The Compress MIDI effect (shown in Figure B.10) compresses or expands the velocity values of events on a MIDI track by adding or reducing the Note On velocity of these events. The Compress effect has three controls: the Threshold level, the Ratio, and the Gain control. The Threshold level determines the velocity value needed to trigger the compress effect. The Ratio can act as an expander or a compressor depending on the value set in this field. A one-to-one ratio means there is no change in the velocity values. A ratio greater than one-to-one compresses the velocity values by that proportion, and a ratio that is less than one-to-one expands the velocity value by that same ratio. For example, if you have a ratio of 2:1, for every two values passing the threshold, only one is added to the final velocity. So, if you have a threshold of 80 and play a velocity of 100 with a ratio of 2:1, the end velocity result is 90. On the other hand, if you have a ratio of 1:2, playing a note with a velocity of 90 using the same threshold causes the velocity to move up to 100.
