"This Roland has been modified here is information about the stock setup and then info about modifications.The Stock Juno-106 is a six-voice polyphonic and programmable analog synth with one digitally controlled oscillator (DCO) per voice. While classic monophonic syths used two or three oscillators to create a fatter sound(check mods below), the Juno-106 uses built-Chorus to fatten up its sound with dramatic effect. The nature of its DCO meant it was stable and always in perfect tune but still warm and analog. There is an excellent 24db/oct analog low pass filter with plenty of resonance and self oscillating possibilities and a non-resonant high pass filter. The programmable pitch/mod bender can be assigned to control the DCO pitch, VCF cut off, and LFO amount all at once or individually. There are 16 MIDI channels available and MIDI SYsEX data can be transmitted/recieved from all the sliders and buttons for total remote control and sequencing capability. A switch on the back of the keyboard next to the MIDI port allows the user to switch between three types of MIDI modes: KEYBOARD, HOLD, BENDER, PATCH or ALL DATA(including SysEX).
Fully restored with Mods: This unit has been Completely rebuilt, new DCO chips, and battery. and modified with a DUAL VCF/VCA ICS which give it a thicker full sound(the extra filtier/vco chips are located under the PCB) The keyboard has been completely re-graphic in purple and yellow with matching LEDS and dark walnut sides. It comes with a printed copy of the owners and service manual. A matching spec(other than color) keyboard also modded by Roger Gastrow now resides at Henson Studios in California."
