"Marion Systems MSR-2 16 Voice Analog Synthesizer
Unit has Two Analog Synth Modules and was customized by Marion Systems
This auction is for one of the most powerful 1 unit
analog synthesizers ever made. Two MIDI inputs and a 25 pin
connector on each module to access all sorts of advanced features.
Full MIDI implementation with velocity and aftertouch
This MSR-2 comes with Original Manual and Original Power Supply
Main unit 1.09 O.S. and 1.13 O.S. for each of the two ASM modules
A new Energizer battery was installed 3 years ago so should be good
for another 15-20 years, but back up your stuff if you create great sounds.
Customized by Tom Oberheim and Marion Systems
In 1998 I sent the unit back to Marion Systems for an upgrade.
They added a second Analog Synth Module (ASM) and upgraded the O.S.
I was working as a tech at E-mu Systems and Tom Oberheim called me
at work and we talked about my love for all synths Oberheim. He told me
he could disable the EQ in the MSR-2 and get an addition al 3 DB of gain.
I told him that would be great, they removed EQ, and the volume gain is significant.
Tom was really nice and it was an honor, as an EE myself, to talk to him.
So yes this is a customized MSR-2 by Tom Oberheim and his Marion Techs.
The Eq section screen is still there in software, but has no effect since disabled
Custom programmed SuperPatch sounds
I have created several Super Patches as shown in video below to show the power
of this synth. The Super Patches are organized in groups
10 Bass Super Patches
10 Pad Super Patches
10 Lead Patches
and Sound Effect Super Patches
The factory patches are installed in the first 200 patches on each
Analog Synth Module.
Search three words Silicon Breakdown Oberheim to see my love for the
Oberheim synths. I have a picture of Tom Oberheim hanging in my studio.
I have owned the website Silicon Breakdown since 1999, which is devoted
to American analog synths.
This MSR-2 has been used in many songs by Mad Science Lab,
search Spotify, Apple Music or my music site MadScienceLab(.)com
I only sell one or 2 synths a year from my collection.
The unit has never had any mechanical or audio issues and is 100% working."
