Roland Juno 106
Programmable Polyphonic Synthesizer (1984)

 

Successor of the Roland Juno-60 synthesizer, sought-after for the Midi interface and the polysynth structure.

panel

info KEYBOARD Main panel features a basic segment display, 20 levers, 2 knobs, 3 switches and 34 buttons. On the left side there is a joystick for pitchbending or modulation assignable to filter cutoff.


Back panel terminal connectors:
- Midi interface
- tape interface
- main out
- headphones
- master tune trimmer
- program change pedalswitch input
- sustain pedalswitch input.



editVOICE core CPU NEC D7811G manages 6 voices polyphony, each voice is composed by 1 DCO digitally oscillator controlled based on 3 IC X MC5534A WG waveform generators.


STRUCTURE: each DCO features 4 summable waveforms:
1- square with variable width
2- triangle wave
3- square sub-oscillator (set to 1 octave lower)
4- white noise generator.
Check out TEST: juno106 vs Juno60



dco oscillators


waveforms




adsr ENVELOPE 1 ADSR (4-segments) EG for both:
1- VCA amplitude
2- VCF cutoff filter.
The VCA EG can be triggered in GATE mode following the key pressure.


VCA

 

lfo LFO single delayed triangle modulator, relative frequency range from 0.1 to 30 Hz and 3 destinations:
1- DCO pitch
2- VCF cutoff
3- DCO pulse width.

filter FILTER
analog filter based on IC 80017A (also acts as an EG) with 2 modes:
1- Lowpass resonant (self-oscillating) at 4 poles
2- Highpass (not resonant).

edit PERFORMANCE the DCOs can be sequenced in 3 playmodes:
1- poly1 voice is assigned restarting from first free available
2- poly2 voice rotate always from 1 to 6
3- unison stacks up the 6 voices, sadly it misses a DETUNE option
TIP: press [poly1] + [poly2] to access to access special unison.



effect EFFECT chorus is based on BBD chips (2 X MN3101 + 2 X MN3009) and 2 presets.




effect
MIDI the J-106 offers one of the most impressive Midi implementation for the time: in fact all sliders sends and receive Midi exclusives systems.



effect MEMORY:
-128 patch RAM
Sounds patches can be saved / load either by Midi exclusive dump or tape player.
Battery replacement: a BR-2325 lithium battery soldered to the mainboard.


 

editREPAIR the infamous 80017A IC is an enclosure of 3 famous chips the 3109 + 2 X BA662, IC drowned into a kind of resin that after years dilates causing a common IC failure.
There are 2 ways to fix it:
1- Clone replacement: companies produce IC clones (analogue renaissance / Naab ) replacing IC involves soldering and re-calibration VIDEO TUTORIAL
2- Acetone soaking : basically you have to soak the IC for some days then the coating should be removed allowing some direct repairs on de-encapsulated IC VIDEO TUTORIAL

comment


Review "the 106 is a swiss-army knife for polysynth sounds at affordable price: it unleashes some warm strings, nervous techno bassess and famous electro-brasses."
