Synthtiseur is a digital / analog Crumar firm. It dates from 1978, its appearance is apparent Aesthetics other brand keyboards the same era. (Organ T1, T2, and Multiman Performer).
It consists of a four-octave keyboard and a panel CONTRL fate CRER sounds using the various functions. The sides are dark wood panel in CONTRL mtal be inserted in a black wooden case, covered with dun gray vinyl with cornires function in metal. The srigraphie is red and crme.

The "Heart" of the synth has 2 oscillators monophonic CONTRL &#39;digitally&#39;, hence its name &#39;digital / analog&#39; (A Premire in 1978 ..) All other components are analog. This digital voltage CONTRL silent sense to bring more stability to the oscilloscope, including the holding of the tuning ... silent era that still problmatique on synths analos
For a tilt, there are four waveforms: triangle, sawtooth, square, square and a variant called &#39;Pulse wave&#39;. For the two tilt was 3 waveforms: triangle, square and sawtooth. oscilloscope both have their pitch, height doctave 32,16,8,4, and volume.
The Tone and rsonance be modified by a filter 4 trs effective peoples (CONTRL &#39;cutoff filter&#39;, &#39;rsonance&#39; and &#39;ADSR range&#39;. It also has two ADSR circuit, a VCA which modifies the amplitude of the sound, and a VCF (filter 4 peoples.)
ADSR for each, you can change the Attack, Decay, Sustain, and Release (In the name o &#39;ADSR&#39;!) For fans of Solina and other CS 80, it also has some polyphonic ind pending mulant old strings .. (Not Miss, violins ...) with high-pass filters, low pass, a pitch, doctave 3 heights (16, 8, 4) and in a CONTRL dinjection LFOs.
The polyphony is full for this sound, all the notes on the keyboard can thus be playing at the same time. Ideal for the agreements.
Part 2 is available to the modulation oscilloscope and the part polyphony. It has 2 LFOs with adjustable speed and form donde: sawtooth, square, and down sinusode descalier. A delay (delay dinjection sounds in the LFO) is adjustable and two assignable LFOs at.
Grace the LFOs can be CRER effects chorus, vibrato, tremolo.

The LFO section allows MIXER send each tilt (poly or mono) in the LFOs.
Keyboard Control function can adjust the filter according to what lon played on the keyboard, the more we play sharp notes, the sound becomes brighter.
White noise function or pink noise, volume adjustable, allows the dapporter EHJV on low or Dimiter sound waves or wind.
Finally a Glide function which is actually an adjustable Portamento speed.
For connectivity, there are two exits gnrales, high or low impdance, a headphone output, an output section indpendante for polyphonic, and between an external instrument to pass through the filter. All connections are TRS 6.35, except one I / O Gate TRS 3.5.

UTILIZATION

The unit did not have memory, so once a cre Quon Quon sound and wants to preserve, paper, pen and scratching! Hint: Take a picture of the synth view, reverse the color of the picture and make copies for patch configuration of sounds. As has every time you quune his flat Naur that you draw the button positions on the sheet, saving time and ensured sore head pricks!
For the manual, I had sought for months to find it on the internet, but hey, cest so easy to make sounds, it all under the eyes of lanalogique lavantage cest!
The keyboard nest not dynamic, but yen is no need.
Sounds are trs granular or fine LGERS trs, adpend. If you like the song of MODEL KRAFTWERK, grain sounds of Depeche Mode&#39;s first album, cest done everything in the Crumar string. Can be obtained purely techno sounds, but hey, cest not my thing the strings are polyphonic lectures, the chorus of LFO gives them a phnomnale scale, can be more quune Solina, but hey, cest still a matter of gots ..
You can also CRER percussive bass sounds with a lot of PCHE
In fact, the number of sounds dpend the time you spend on the machine, and your imagination! Amateur boxes presets, go your way!

SOUNDS

JOperation this little synth prs 2 years, I bought it because lai jtais looking for an old analog not too expensive, and I am also an amateur Crumar keyboards.

In terms of default, jai sometimes ashamed to say, but this synth is a gulf dough, not as reliable!
It crashes every time I watch it.
No, jexagre! But it&#39;s true that, unlike other keyboards of the brand, it is for its reliability rput catastrophic! (Technology matrise yet?)
He can walk for days without any problem, then the next day, nothing! And since I&#39;m not lectronicien, each bin must be in Lemmens lhomme in white coats.
In addition, this synth is quite heavy (30 kilos)

In terms of quality, warmth and texture of the sound is unique, its trs LFOs are effective, and specially to mention the superb Strings.
In addition, this synth is quite rare. (But is it a quality?)

OVERALL OPINION

Finally, I would say that the firm did not Crumar had success MRIT what they have manufactured great machines, IMMEDIATE recognizable both sound and Lapparent, until the Sometimes the DX7 in 1983. It could not survive nont Monopole of Asian brands. Too bad ..
