JUNO SERIES its simple user interface and the absence of ringmode, crossmod or any other „dirtmaker“ is responsible for the juno’s sound that always sounds „good“.. but is also reduced to the minimum. it has DCOs (one DCO plus SUB with pwm,saw,noise), it’s not as versatile like the jupiter series but this may be the cause for the name: juno a moon of jupiter?.. it’s LFO has one waveform (saw) like the alpha juno series, but its 20hz max (the alpha series LFO is much faster) did you know the Juno106s? it was a Juno106 with loudspeakers built in!! rare! and another strange version the HS60 with speakers for the „hobby“ market. Racked juno 106 = yes, its the mks7 midify a juno ? die modelle juno60 und juno106 haben als unterschied speicher und der 106er midi. simple DCO-VCF-VCA.. but self resonating 24dB/oct lpf filter 1 VCO with subosc, PWM, white noise and static 4 step hpf. this is the simplest model: no midi and no memory ;) want mono/uni mode on the juno? just press key transpose while power up (hold!) and you will hear all 6 notes to the last key held down! ;) there are some test programs on board, that can be reached by 5 (hold down when you have plugged something into the patch select jack, then 4 or 5 for bank 8 and 9. THE ALPHA JUNO SERIES (1 and 2 and mks50) are also juno synthesizers, but with a complex envelope , 1 VCO and SUBOSC , LPF 24dB/oct, quite fast LFO, nice with pg300 programmer, the alpha juno 2 has velocity sensitive keyboard (5 oct) and a card slot, the apha juno 1 has 4 oct. keyboard., no card slot. the UI is quite digital, so try to use the programmer (sometimes as expensive as the synth itself).. | roland juno synthesizer series racked juno? yes! MKS-7! incl TR707

Roland Alpha Juno 1 / Alpha Juno 2 Rack: MKS50 / pg-300 also: mks50 as rack version. – programmer: pg300 came out 1986 often most ppl. do not believe it can sound like this: alphajuno.mp3 audio demo.. this little 4 oct (alpha ju1) and small synth is really a JUNO! also available as 5 oct keyboard (alpha ju2) only the ju2 has velocity and aftertouch sensitive keyboard but the ju1 can receive velo/aftertouch data via midi! same for mks50 (well ,not keyboard! 1 unit rack machine!) OSCS: it provides: DCO with lots of pulse wave variations and separate PWM „lfo“. in ADDITION to that you can add sawtooth including varations of modulated symmetry (not PWM but quite close!) Filters: FAT sound!! imo it is much richer than that of a JX8p or JX3p (and they sound quite fat!).. so it is a real juno, made in 1986 – anyway a full fat synth. maybe a „secret tip“ these days.. chorus (incl rate setting for mod.) dynamics for filter,dco,vca env: gate or a multistage env (see image on the right)–> T1-T4 rates and 3 levels can be set! – quite fast – so also good for basses and percussive sounds LFO: sine only but quite fast!! (really fast!).. not as fast as the jupiter 4 LFO, but app 40-50hz (estimated).. so it reaches audio.. can be routed to filters,dcos,. lfo can be „faded in“ (delay paramter) in fact: you have 3 LFOs : the above mentioned (controlling DCO or/and VCF), the PWM lfo (about 20hz max) and the chorus lfo (also about 20hz max), the main lfo is as said audio speed!. VCA: gate, dynamic gate or envelope. (no lfo mod..) | Roland Alpha Juno 1 / Alpha Juno 2 look at this table: see the pulse and saw variation (one osc at same time)? – click the pic to see the ENV diagram! the PG 300 programmer.. for alpha juno & mks50 there was another „hobby“ version under the HS10 name.. rare but not much different.. (possibly with built in speakers) restore factory presets (not really „good“ idea) but if you like to hold 4 and 8 at power on (in poly mode) or 3 and 7 in mono mode. will of course erase all sounds, tune/midi chord memories etc. bank A will completely overwritten.. |
