    still one of the best single market!

    Sequential Circuits Pro-OnePublished on 09/25/13 at 04:54

    Unfortunately mine has the keyboard completely unplayable membrane (to be replaced by a type J-wire)
    for those who already know the SH-101 digital control part (sequencer, arpeggiator) is the same, it just lacks the slide of sequencer 101

    Connectivity: Stereo OUT, CV gate in and out; Filter CV in, Audio IN

    UTILIZATION

    The second oscillator can be turned into a second LFO (switch Lo-Freq) super complete: wave forms of stackable square with PWM ... otherwise remaining in audio frequency it can make FM (linear), the modulating audio filter, kind of Ring-modulation effects .... sounds using the Synchro VCO are truly monstrous (the specialty of Pro-5).

    Connectivity: Stereo OUT, CV gate in and out; Filter CV in, Audio IN

    UTILIZATION

    The second oscillator can be turned into a second LFO (switch Lo-Freq) super complete: wave forms of stackable square with PWM ... otherwise remaining in audio frequency it can make FM (linear), the modulating audio filter, kind of Ring-modulation effects .... sounds using the Synchro VCO are truly monstrous (the specialty of Pro-5).
    the filter is non-resonant type and color, but really the resonance rises twice as high as most synths it self oscillates at half the race knob, the cutoff frequency of the filter (cut-off) also rises very high, which in some cases allows him to sound like a HPF or BPF
    the modulation matrix has two slots: one direct and one that involves the modulation wheel (ModWheel) but can be assayed and stack different modulations eg send two times the envelope on the filter!

    Now let's review some of the flaws:
    the pitch bender is still quite low design: no return to center automatically, just click in the middle.
    increase the resonance of the filter lowers the volume (that is the filter topology: we can not do anything)
    LFO somewhat limited: no delay (lag), no S / H LFO does not rise in the audio frequency (damage is a 3340 EMC again so it should be possible to easily convert into a 3rd VCO), but three forms of stackable waves (triangle, square, saw)!

    SOUNDS

    sounds cover a very wide range, I 'get it to sound like a Minimoog, sometimes as an SH-101, the treble can be crystalline as a prophet 5 or ultra aggressive, true +: speed envelopes ( there on the modular we can do better), if compared to another synth with VCF CEM3320 was added a circuit hyper resonance (a second feedback loop) there is also a change from relative to the standard mounting CEM3320 to allow the lower cutoff frequency of a lower octave.
    results obtained with CEM 3340 VCOs also depend largely on how they are implemented, I was surprised to see that it is used AOP cheap enough for the time (LM348 I think) but they are the ones giving the fishing, this incredible aggression, the only mono I know that most of the RSF KOBOL potato is the only game to be equal: Minimoog and Roland SH-2

    OVERALL OPINION

    although the sound does not exactly match with my music (rather Roland and Korg) I n 'not get' m apart, each time I lighter bam I come across completely crazy sounds (perfect for the Drum 'n'bass dark well, the break-core ....) and then I fall directly on classy sounds (techno / electro Detroit) leads very funky and "hot" or so "cold" sounds and electronic wholesale impossible to know where we will land is what gives it its charm.

    PRO-ONE, Mythical but fragile!

    Sequential Circuits Pro-OnePublished on 08/06/13 at 23:54
    (This content has been automatically translated from French)
    Features: Refer to section info Audiofanzine Pro-One, it is very well done and well explained.
    In summary this is a mono analog 1981, mine has the serial number 7929, which means that the keyboard is good! (J-wire), knowing that the first models were equipped with up to 1500 a membrane keyboard.
    This synth has a simple design but quite fragile construction.

    This card is attached to a shell ABS screwed onto a metal base.
    The whole is ornamented with two sides in thin wood.

    UTILIZATION

    As mentioned above, the configuration is simple, one button, one function as is usual on an analog of the time.
    The English manual is very brief. But it is not necessary if one has mastered the use of this type of synth.
    I appreciate the use of both VCO all completely independent, unlike other synths or VCO 1 is the master and the VCO 2 is align or not.
    The waveforms can be combined (use a triangle with a sawtooth or square at the same time)
    The utilsation filters is a treat.

    SOUNDS

    I use it mostly in sequence, bass line sometimes in conjunction with my little Moog Rogue.
    Another use: connect to an external sequencer (Roland CSQ100) it is interesting because we can combine the sequence of CSQ100 driving the Pro-One, with the internal arpeggiator Pro-One.
    I sometimes block keys hold the Pro-One in order to modify a sequence.
    Example: If you create a sequence of 24 notes on CSQ100 driving the Pro-One, you simply create an arpeggio of four notes on the Pro-One, and you get a new well synchronized sequence.
    The ideal would be to create a short video to explain everything ....
    This function is not between internal sequencer and arpeggiator Pro-One sets.
    No Midi sync, it does not, so wav recording sequences for inclusion in the compositions.

    OVERALL OPINION

    I have since 1988, following an exchange with a sequencer ROLAND CSQ100, against my Korg MS20 and SQ10.
    PRO-ONE is better at what I'm looking for is not very attracted by sound research and semi-modular patch type that is the MS20.
    I keep my PRO-One until further notice you never know.
    Commissioning still requires a good quarter of an hour wait before being fully exploited, stability VCO requires.
    This is an old grandpa over 30 years.
    When he arrived in my set of instruments after the exchange, the brave synth was operated fairly moderate, with relatively long periods of non-use. The keyboard does not know yet serious worries, bushings (kind of rubber damping pads each key) are still suitable
    I wish to know its history from its former owner.

    GRAIN IS! A REGAL FOR THE EARS!

    Sequential Circuits Pro-OnePublished on 09/27/12 at 04:48
    (This content has been automatically translated from French)
    Like most Pro one, mine has a keyboard problem: some keys are offset in height. this is a known problem due to poor qualitée Bushings beneath the keys.

    To remedy this, it will be a kit Kenton Pro Solo MIDI to control https://fr.audiofanzine.com/interface-midi/kenton/PRO-solo-MK-II/, either (do?) Repair as indicated on this page: http://electrolog.free.fr/

    Pro one is actually a Prophet 5 monophonic and without memory, with a slightly different grain (for better bass sounds from those who own 2 but I have not been able to verify).

    UTILIZATION

    UTILIZATION

    Simple as a button = one function but the possibilities of modulations of the machine are very powerful (section "modulation" to the left of the control panel)

    SOUNDS

    I bought secondhand shortly after trying Arturia Minibrute (for 45 minutes with my headphone, store) even though it is excellent for the price, frankly the sound of one Pro has nothing to see: it is much thicker, bold and dirty!

    Note that I say that without the snobbery towards Minibrute because it allows to (finally) the analog qualitée within reach of all budgets: it can only be a good thing for the music (and after all it is a matter of taste compared to my musical references).

    Another point of comparison: compared to Moog Little Phatty my which also has a big and fat enough sound but without the side "dirty" and oscillators "driftent" Pro one: although a grain interresting, it is I is less alive (but I keep it, eh).

    For those who want to watch the side of the virtual, there is an imitation which it seems is very good: http://www.vintagesynth.com/sci/pro1.php

    But nothing for me to do, I'd rather always true imitation, even well done (ok, there is no waiting for the finding, it is not the same price and it is certainly more convenient , etc. ... it's up to you ...): anyway to use a computer to make music for me for a long time, I'm "distracting" and it is a tool work for me (all day).

    To return to more interesting, I would like to say that I am really impressed by the filter, and especially its resonance envelopes that are faster than I had in a synth!

    Known examples of songs using this machine - "do not go" Yazoo (1982) for most of the sounds and - "a flash in the night" Secret Service (1981): therefore he excelled especially in styles synth-pop of the early 80s since been widely used to this day.

    This video shows the capabilities of the beast: https://www.synthtopia.com/content/2012/08/15/the-sequential-circuits-pro-one-synthesizer/

    Listen to this site (https://www.unease.se/proone.htm) small extract the title of Yazoo recreated with the Pro one:

    https://www.unease.se/mp3/Unease-Dont_Go_replica.mp3

    The sounds of "Do not go," sure, that's him!

    But it is certain that we can do much more titles "funky" electro or "modern" as it is versatile (largely thanks to powerful modulations).

    OVERALL OPINION

    My recent purchase but I'm sure I'll keep it very long (how many machines I sold to later regret such as the famous Jupiter 8 premium today? But hey, it was also for in question at the time: to buy a new machine, it was necessary to resell).

    I think that the sound level (but not the making!), It is in the top three polyphonic synths, Minimoog in mind.

    But unlike the Moog, he used a coast relatively reasonable (for how long? Shhh!).

    ;-) This little synth is actually not that obvious to find secondhand (although 10,000 copies were made).

    One word to summarize what I think?

    YUM!!

    It is a monophonic synth, monotimbral.
    Two oscilloscope waveforms with stackable, a low pass 24dB/oct rsons. 1 3 LFO waveforms also stackable.
    A 2 ADSR envelopes for filter and one for the amp.
    Opportunities for modulation quite impressive for such a small machine.

    Little we know a minimum synthse subtractive, we do what we wants, leads to the low violent shrill through the Fx the most space and most kitsch.

    there are no effects section, no VLOC no aftertouch, and sounds of the fire god.
    The sound is big, fat with potato phnomnale. Especially in a mix.

    OVERALL OPINION

    was going to do a month since I use it and whether in soul / funk, house, teak, and even jazz, he has never taken into default. This is my new friend ... and the first analog!

    I bought € 850, I know it will seem expensive to some, but it is like new, it is a second hand (held by lovers of analog before), and it was very clean Midif .. .
    Qd I lit for the first time I wondered if I replay the old Yazoo ... and yeah ben! and that makes it to death!
    and after twenty minutes I was like mad tweaking knobs all over the place!
    Really a little champion, or a little monster ... it is capable of kouiner as to scold, and all that in a very powerful sound.
    When I know the play I would regret even more the € 850.

Advantage to do so by your drive squenceur prfr twelve o'clock: you have both hands free to activate switches and pots, so to evolve the sound you want. We find pleasure in "impossible to do twice the same decision."

    In fact, some of this dclic "typez back to this machine" when I got to try all the Korg M3. First test of M3: incredible, fabulous, what power, etc.. And the second test, boom, everything is power prprogrammer, when you want it then call back the base sounds and arrangements. After all, when you Listen to Pink Floyd, U2 or Police, there are rarely more than four instruments playing at the same time ...

    SOUNDS

    You can not just ask him either, but once you have recorded your audio connection via the gate / CV - noon, you can overlay one second squence, one is still the troisime ... find the pleasure of polyphony, points and points against home-made and not prfabriqus.

    OVERALL OPINION

    Why sell? If you have it, it's gnral you also have other synths, and with 600 900 euros you will learn, you will not go far at your local pr fr.

Why does Dave Smith remade it not real pro one? His Mopho is far from being a pro one (like his prophet 08 is far from being a "5 ")... Looking back I do it again this choice without hsiter especially since it works well with a trs kenton pro solo. For fun, put it any analog formulation ct (same virus C) and compare poilade ... guaranteed!
