The Roland MKS-20 Digital Piano was once a respected "realistic" piano module, but has given way to affordable samplers with mega RAM. The MKS-20 ruled the '80s with its brother and sister digital pianos, the RD-1000 and RD-300. These digital pianos can still be heard on countless Elton John, country, and techno songs although lately even they are being replaced by samples of the original. The MKS-20 features eight distinct digital tones: three pianos, two electric pianos, clavinet, vibraphone, and harpsichord. Each tone has eight variations stored in RAM. User editable parameters include a three band EQ with parametric mid, chorus depth and speed, and vibrato depth and speed. Chorus and vibrato on/off status can be stored with each patch. Global transposition is available, and handy when layering with other tones. The MKS-20 is a highly expressive piano module, but has a characteristic digital sound that is not easily confused with a real piano. However, it often cuts through a mix better than a real or sampled acoustic, and sounds wonderful when layered with pads and a little delay or reverb. For that unmistakable '80s sound the MKS-20 can't be beat, although the Roland P-330 digital piano module comes extremely close.
