Also known as
ProMars Compuphonic, MRS-2 is the
monophonic little brother of
Jupiter-4.
The two individual
VCO:s along with the high-pass and
resonant low-pass
VCF:s create a
thick and
Jupiter-like
sound. An
ADSR envelope generator is available for the
VCA as well as the VCF. A
white noise generator is also included.
There are 10 (quite
cheesy)
preset sounds along with 10
user programmable patches.
"Compuphonic" is yet another fancy
buzzword from
Roland, standing for the patch
memory.
The controls are typical for a
vintage synthesizer, with plenty of
sliders and
knobs making
programming the MRS-2
quick and
simple. They are arranged a lot like in the
SH series and the
JP-4.
Also included is a
pitch/mod
wheel which can affect either the LFO, VCF or VCA.
The
unit looks like a
shrinked version of Jupiter-4, with a 37-note
keyboard and better situated patch
buttons. It was in production from
1979 to
1982.
