Sequential Circuits is one of the names for vintage synthesizers. Founded by synth wizard Dave Smith, co-inventor of MIDI and general pioneer in the field, Sequential Circuits held in its hands some of the biggest synth models ever created; for instance, the Prophet 5 and every member of the series thereafter. Now given new life as part of Dave Smith Instruments, Sequential Circuits has made its return with the Prophet 6, a fully analog synth loosely based on the famous 5. Look for vintage, new, and used Sequential Circuits synthesizers on Reverb.
