"The SH-7 is a rare and great sounding duo-phonic analog synth from the late 70’s. It has that great classic look, sound and feel of the early Roland products.
A very flexible vintage synthesizer which allows each user to creatively modulate and tweak the sounds. Mixer allows colouring of each sounds which also can be used to distort sounds. This amazing piece of unit is the perfect key to techno sounds and effects.The biggest SH series non modular synth. A mixture of a bit SH5 and System 100 but still different. 2 real ADSR Envs, filter FM and a weak but strange sync sound. Duophonic but not 2 voices, so VCO1 and VCO2 can be controlled by the keyboard.
Has an extra sample and hold. one LFO can trigger ENV(s). Has external input, fast Envelopes and nice resonance with the help of filter FM by OSC2 or noise mod. There is a special mixer in VCO1 (a) ranging from 32' to 2' like the SH-3A and lets you mix square waves of each octave range (plus the VCO1 selected wave called VCO (b) )
The SH7 is the flag ship of the SH Series. Both Envelopes can be triggered by LFO, keyboard or both, the VCF can be modulated by 5 sources switchable to another alternative, so it's 10 but not at the same time: env1 (positive and negative polarity), LFO, or S/H, keytrack or pedal, VCO2 or Noise, Envelope follower (positive, negative polarity)
This unit is full working order and in very nice condition too."
