The System 700 consists of the Main Console (pictured center), the Keyboard Controller, and five optional "blocks" (pictured above surrounding Main Console). A complete system as pictured above has a total of 47 modules (see Tech. Specs for modules info). Most System 700s were sold in the following configuration blocks:
"Block 1" (Main Console): This is the Heart of the System, and it contains all the basic modules necessary for a professional system. It has 3 VCOs, 2 VCFs, 2 VCAs, 2 LFOs, 2 ADSR egs, Noise, Ring Mod, Voltage Processor, S/H, Envelope Follower, "Integrater" (Lag Processor), Mixer, 2 X 5 multiples, Headphone Monitor Module, and an Output Module, which includes Stereo VUs, a six-position test-tone, Phase Shifter, Spring Reverb, and voltage controlled Panning. Most common module connections (power, cv, gate) are made internally for easier patching.
"Block 2" (Keyboard Controller): The 61-key two-voice Keyboard with Portamento and Pitchbend controls.
"Block 3" (Sequencer): a 3 X 12 step sequencer with Pulse Shaper, Clock Oscillator, and Series / Parallel output sections.
"Block 4" (VCO Bank): 6 VCOs, a dual ADSR envelope generator, LFO, Sample and Hold, 2 X 5 Multiples, and a small Mixer.
"Block 5" (VCF/VCA Bank): 2 VCFs, 3 VCAs, 2 dual ADSR envelope generators, 2 X 5 Multiples, and a Gate Delay.
"Block 6" (Interface/Mixer): a Frequency-to-Voltage Converter Interface, a VCA, 9-channel Audio Mixer, and a Fixed Filter Bank.
"Block 7" (Phase Shifter/Audio Delay): a 2-channel Phase Shifter and a 2-channel Audio Delay, 4 input Analog Switch, and a (1X12, 1X4, 1X8, 3X4) multiple.
Blocks 3 through 7 were options and could be arranged by the original owners in any way. Roland also released a Lab version, the "Laboratory System 700", the size of one lower wing cabinet with 3 VCOs, ring mod, VCA, mixer, LFO, Sample & Hold, Dual Envelope Generator, and VCF.
