Roland System 100

   (0 reviews)

The System 100's filter is many a synth geek's desire even if the oscillators can be unstable at low frequencies but they are solidly built instruments and modules.

The modules - the 101 synthesizer, 102 expander, 104 sequencer and 103 four-channel mixer with built-in spring reverb and mono fx send/return & the 109 speakers could be used independently, but there was no true modular flexibility, as with the later Roland System-100M and the Roland System 700. The component parts gave an expandable two-oscillator monosynth with sequencing, monitoring and effects capabilities.

Each unit is independently powered so that there was no weakening of oscillator power due to complex patching. The 101 and 102 are internally normalised so they can be used without patching at all. Also, uniquely for the time, the 100 didn't have the oscillators "locked in" to fixed footages or pitches, which allows maximum flexibility for sound design. It can also be used with a MIDI-to-CV[disambiguation needed] converter, as it supports the 1v/oct standard.
