Analogue Solutions has announced the Series 700, a full-scale recreation of Roland’s System 700 modular synthesiser, with pre-orders opening October 29 following a debut at Synthfest UK. The original System 700 was Roland’s most expensive instrument, and complete units now trade on the secondhand market for upwards of £150,000 GBP when they surface at all. The Series 700 is built directly from original schematics, with circuit changes kept to a minimum and made only where specific vintage components could no longer be sourced.

The physical dimensions of each block match the originals exactly. Six blocks are available: the Main Console (Block 1), Analogue Sequencer (Block 3), VCO Bank (Block 4), VCF/VCA Bank (Block 5), Interface/Mixer (Block 6), and Phase Shifter/Audio Delay (Block 7). Custom knobs, slider caps, switches, and potentiometers were commissioned to replicate the original’s look and feel. The one addition beyond the original spec is a basic MIDI-to-CV converter, included mainly to allow the three-voice 12-step analogue sequencer to sync with MIDI.

A keyboard controller, Block 2, is being developed separately as an optional upgrade. Based on Roland’s original 701A design, it will offer four-channel polyphony, velocity CV output, MIDI in/out, and minijack connections compatible with Eurorack and vintage monosynths.

For producers chasing the sound behind records like The Human League’s “Dare” without spending six figures on a fragile vintage system, the Series 700 offers a direct path to that circuitry in a new, serviceable build.
