Stereo Chop Chop is a JSFX from Smashed Transistors aka Thierry Rochebois. It’s a pattern gate with separate controls for left and right channels. It’s pretty powerful and a great way to liven up pad sounds and more.
Here is a gate effect i wrote for Ze Strings Thing to get chord stabs stuff. It embeds many gate “patterns” that are synched to the beat_position. It is stereo with many parameters such as density, gate length, attack and release time.
