"For my 'One Synth, One Song' series I had a little hard time finding something
proper for the Quasimidi Sirius. Three melodic tracks and four drum tracks plus
a rather poor effects section ain't the best ingredients for full arrangements,
and the sound design is very limited too. Just when I rediscovered
Propellerhead's Rebirth RB-338 I thought hey, why not some 90s acid stuff? The
Sirius sounds dirty after all. It's not much other than a few squeaky synth
lines, a TR-909 set and some Hohner strings. But maybe some of you enjoy this
anyway."

Access Virus Rack XL SN 10200035 w/ Custom Blue Aftermarket Display
Note: links to listings are affiliate links for which the site may be compensated.
via this auction
"The Virus Rack XL is a 1U rackmount version of the Virus C desktop synthesizer made by Access Music. The synth only sold for 2 years before being discontinued, quite hard to find as not many were sold.
The unit has 3 stereo outputs, 1 stereo input (for adding effects to incoming sounds) MIDI in/out/thru, and sounds fantastic. Though the unit does not include as many features as the newer Virus Ti, the think sound of the Ti series makes the older Virus A/B/C units a much more desirable instrument."
"Includes an aftermarket black/white LCD screen to increase contrast and readability (a great modification indeed!)."
The original was red. You can see some in previous posts here.

PAIA FatMan Classic Analog DIY Rack Synth

"PAIA FatMan Classic Vintage Synth: 19" Rackmount with Original Blue Face and 12V Power Supply.
The FatMan has all the features that give analog its big bottom and punch in a MIDI-controlled package. The classic Voltage Controlled normalization is brought up to date with a Velocity CV not available on pre-MIDI synths. Pitch wheel modulation is supported and Pitch and Velocity CV, and Gate outputs are provided on the front panel for driving PAiA or other linear-response synthesizer modules.
It is a small monophonic analogue synth with two oscillators, 18 rotary knobs, 3 switches and no keyboard. There is a low-pass resonant A(S)R filter, an ADSR VCA and portamento. There is MIDI on-board and as the FatMan uses control voltages to operate the MIDI really acts as a MIDI-to-CV converter. This means that it's CV outputs can be used to control other old analogue gear you may have around.
The FatMan's classic normalization of two VCOs, VCF and VCA is enhanced with MIDI pitch bend and a Velocity Control Voltage routed to both filter and final amplifier. With transpose and offset, pitch covers seven octaves starting from a room-shaking 65 Hz., four octave response under MIDI control.
And all those knobs. They invite experimentation and invention in ways that a single control with functions buried under layers of obscure menus never can. Just a few hours with the FatMan will teach you more about the nature of sound than you might ever learn otherwise. It's as at home in the physics lab as on-stage."
