The Vintage Keys is a digital rackmount synthesizer that emulates the sounds of classic vintage synths. For an early 1990’s ROMpler, this sound module was compact and actually sounded really good, loaded with good samples of vintage synth sounds. Just like the classics it has Portamento, a VCF (filter) and a Chorus effect. It has a lot of modulation capabilities which are all real-time and MIDI controllable. It does, however, have the typical brittle digital sound quality usually associated with digital sound modules, but it still makes nice pads, punchy bass and cool filter swept leads and works great for background synth sounds.
