I’ve just seen this:
"Steinberg Karlette
This plugin is so old that it pretty much qualifies as a vintage effect in its own right. Among the first VST plugins, it’s a free echo effect similar to the old WEM Copicat. It may not be cutting edge, but it certainly does the job, and that’s what counts"
I’m gonna have a play so I’ll let you all know the results!!
