Roland SH-7. The SH-7 is a 2-VCO, duophonic analog synthesizer with a 3 1/2-octave, 44-note (F-C) keyboard. Both VCOs can be switched between triangle, sawtooth, square, and pulse waveforms. VCO2 can be detuned from VCO1. Pulse-width can be controlled by the LFO or ENV1 (envelope generator 1). Each VCO has three sliders that adjust how much it is affected by the LFO, S/H, and a function called “Autobend”. Autobend allows the VCO to slide up or down to a pitch. The Autobend function has controls for polarity and time. VCO1 has an additional square wave section (called VCO1B) wherein five sliders control the volume of each square wave (2’, 4’, 8’, 16’, and 32’). This works in much the same way as an organ’s drawbars do. The SH-7 also features a ring modulator where the first input is VCO1 and the second is switchable between VCO2 and an external signal (via the external input jack in the back). There is a switch for oscillator sync. However, it does not achieve the usual “sync” sound. A mixer section provides five sliders, VCO1A, VCO1B, VCO2, Noise, and the last one switchable between the Ring Modulator and the External Signal. http://www.synthmuseum.com/roland/rolsh701.html
