Roland System-700

The first modular system built by Roland. The full system consists of 7 "blocks": Block 1: Main Console Block 2: Keyboard Controller Block 3: Analog Sequencer Block 4: VCO Bank Block 5: VCF/VCA Bank Block 6: Interface/Mixer Block 7: 2ch Phase Shifter/2ch Audio Delay [Modules:] 701A: 5-octave 61-note keyboard 702A,B,C,D,E: VCOs with four waveforms (sine, triangle, sawtooth, and rectangle), PWM, and range knobs (LO to 2'), and a pitch control (+-12 semi-tones) 702A: has a PWM input and slider, and LFO1 mod input is hard-wired 702B: has a hard-wired ADSR1 and LFO1 modulation inputs and sync 702C: has a Sample & Hold and LFO1 input and sync 702D: like A but with a socket instead of hard-wired mod inputs 702E: like B&C without the hard-wired inputs 703B,C,D: 12dB VCFs 703E,F: 24dB VCFs 704A,B,C,D: VCAs 705A: Dual Envelopes 706A,B: LFOs (rate/delay) 707A: Envelope Follower 708A: Noise and Ring Modulators 709A,B: Sample & Hold Modules 710A,B: Multiples 711A: Output module (Stereo VUs, a six-position test-tone, a Phase Shifter, a Spring Reverb, and voltage-controlled Panning) 712A: CV Processor 713A: Gate Delay 714B: Frequency-to-Voltage Converter, Envelope Follower 715A: Multimode Filter, Mixer 716A: Mixer 717A: Analog Sequencer 718A: Power Supply 720B: 2-channel Phase Shifter 721B: 2-channel Audio Delay 723A: Analog Switch Date Produced: 1976 - 1982
