2020 Modulating Delay is an analog-style echo with modulation options including a breakout to allow in-chain processing. All of this is covered in the video. This device has appeared in almost every mix, client & personal, Country, Pop, Metal, Synthwave etc since I made it. If you don't already have an Echo that you use for everything, this could be it. There are four versions in the download: -VST2 original skin -VST2 Matt Boa skin -VST3 original skin -VST3 Matt Boa skin All are 64-bit Windows (no Apple). You only need one version. Use the VST3 version if you can. Please be sure to watch the whole video and install the whole Folder correctly. If it isn't working, it was installed wrongly. Always put the whole Folder in your VST Folder or the device will not work. -VST 2 can go wherever you have your VST Files -VST3 MUST go in OS(C)>Program Files>Common Files>VST3 For any/all Support requests please only use the YouTube video discussion. p.s. please note that this device deliberately does not have BPM Sync as it doesn't fit with the architecture.
