EchoSwitch Tri-Mod Echo 64 Bit Windows VST3 (no MacOS version) is a unique character Echo/Chorus/Reverb that applies three modulations to the effect to deliver a constantly moving feel that the listener perceives as depth, sheen, or sparkle. This effect is quite simple in reality but the controls required to use it are a bit dense. Deliberately there are no presets as this really shines only when tuned by feel to the sound source and song. You can of course save your own presets if you desire. The device is covered in the Video below which is the Manual. Please be sure to watch all of the video before asking questions or for support. All support via YouTube video comments only. :-)
