1. Independent Gate inputs for both envelope generators.
2. Voltage control of internal clock, with input attenuator.
3. Voltage controlled switching of electronic switch.
4. Slow random voltage with variable bandwidth.
5. Three-position switches for normalled connections on selected inputs.
6. Monitor speaker disconnect funtion for "headphone only" monitoring.
7. Final output disconnect switch.
8. Voltage controlled resonance on VCF with modulation input attenuator.
9. Manual and voltage control of pulse width on VCO 1 with associated input attenuator.
10. Reset synch on VCO's.
11. Foot pedal signal attenuator with +10 volts normalled to input.
12. Twelve-position chromatic transpose switches for VCO 2 and VCO 3 with 
assignment switches(On/Off, I think, see below).
13. Comparator with voltage controlled threshold.
14. RMS phase modulated synch for VCO's.

Same issue shows picture of Mini mods.

1. Synch switches for VCO 2&3.
2. Chromatic transpose knobs for VCO 2&3 with on/off switches.
3. "Contour" switch above Osc. 3 control switch says "VCF/Both/VCO2" (?)
4. Underneath "Glide" knob is new knob labeled LFO4 (0.1-30). Next to that is as selector
switch for Triangle or Square wave. The modulation mix knob now has a toggle switch
in place of the Noise setting, switching between "Noise/LFO4".

Also in issue is an add for "DEVICE" magazine, but I've never seen a copy.
Anybody have some information?
