Steinberg are doing it again!
I love this old stuff… and I use it.
Neon — Polyphonic synth featuring two oscillators, ADSR envelopes, an LFO and a resonant filter
Karlette — Vintage tape delay with four independent delay heads and tempo sync
Both instruments are available in VST 2.4 plug-in format (32- and 64-bit, PC and Mac OS X) and can be downloaded free of charge from the Steinberg website.
