Cwejman S1 MK2 Back in Production

The Cwejman S1 MK2 is back in production priced at 3500€ or roughly $4000. Curious if it will be the battleship green or off-white model below.

via Cwejman

"The S1 is a semi-modular, analogue monophonic synthesizer. It is easy to get started with since it is prepatched for optimal use of its sound producing possibilities and eliminates the need for external connections between modules during use. Each module can be disconnected and used separately, e.g. to control or be controlled by other instruments. This flexibility enables and simplifies experimentation with creation and reproduction of sound

Features
3 oscillators with seven waveforms
ring modulator
FM
sync
portamento
noise generator with three noise shapes
low pass filter with selectable 4 / 6 poles and quasi band pass mode
multi mode filter with selectable 2 to 6 poles and three modes
wide range envelope generators
master amplifier with build-in overdrive stage
LFO with seven basic waveforms and wide rate range
extensive modulation of, virtually, all synthesis parameters
build-in MIDI to CV/gate converter with 16-bit resolution
several parameters can be voltage controlled by external signals and, simultaneously, control external devices by the build-in MIDI converters voltage outputs (see Rear Panel)
The S1 is a stand alone instrument and the possibility with patching and integrating it into an external modular (or semi-modular) synthesizer makes it extremely flexible."

ELEKTRONIKA EM25 - Vintage Analog String synthesizer USSR Soviet Russian

Note: links to listings are affiliate links for which the site may be compensated.
Published on Jan 14, 2019 GLvintageSHOP

"EM-25 is an interesting Soviet string-synth that looks and feels like a curious cross between Moog Opus 3, Yamaha SK15 and ARP Solina. Like other Soviet synths, has got a distinct sound of its own and can easily compete with synths that have grown to become classics.

Organ has great vibe - I like its etheral and gentle vibe in upper register. It has one percussive drawbar (again a plus for total tonal variety).
EM-25's organ is quite interesting, potent and woody with full registers, almost acoustic sounding. With a touch of LXP-1 reverb, a single drawbar turns into real Cathedral organ!

Synth section (called brass on EM-25) is VCO fixed preset on both, with full filter section - but only one filter for all voices.

All said, EM-25 is unique and rare and a real stringer."

"If you are looking for the ultimate in Yamaha FM synthesis this is one of the finest examples you will find. The TX802 is a rack-module version of the DX7mkII with full 8-part multi-timbral operation for sequencing and/or key mapping. It has 16-voices of polyphony and six digital FM Operators. There are 128 preset and 64 user patches for your sounds, as well as an external memory cartridge slot.

This particular instrument was used on sessions in the 1990s for artist such as Phil Collins and Whitney Houston. Not only is the unit in excellent cosmetic and operating condition, but it comes with a full internal and card bank of the very BEST DX7 sounds available. These were hand selected using a midi editor librarian, loaded into the internal memory and also the extra RAM cartridge (included).

The original LED display is working perfectly, and a new internal battery has been installed."

"If you are looking at this, then you know what it is. Much much richer and more expressive than the cut down VL70-m

NEW bright LCD display just put in. Easily more readable than the original part.

New floppy disk drive also replaced and tested.

Full Factory Test Menu Performed (see picture) and passed. There's one slight quirk with this board. On boot up it will say the internal battery is low. I have replaced the battery and the message still comes up (only once each time it is powered up). The message can be dismissed, so obviously it doesn't affect usage.

Comes with a disk, with 3 factory sound banks as shown in one of the pictures.
1. FULLCTRL: Full Control using breath controller, plus 2 mod wheels
2. NOBREATH: No breath controller
3. STANDARD"
