 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 was 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

 converter, as it supports the 1v/oct standard. more modules were apparently planned, but none were ever produced.

The System 100 is still sought-after due to its filter, sequencer and patching capabilities, though the oscillators can be unstable at the lower frequencies and the keyboard is prone to mis-triggering and double-triggering. The Roland SH-5 AND SH-7 are very similar in styling but both are complete keyboard units, as opposed to the modular System 100.
