Sequencer / Arpeggiator • Immediate performance workflow
The Roland SH-101 is a monophonic analogue synthesizer introduced in 1982. It is known for straightforward subtractive synthesis, a strong low-end (helped by its sub-oscillator), and a simple performance-oriented layout. Common uses include bass lines, lead sounds, and sequenced/arpeggiated parts.
The SH-101 uses a single voltage-controlled oscillator (VCO) with selectable waveforms, plus a sub-oscillator for additional low-frequency content. The signal is shaped by a resonant low-pass filter and a basic modulation section (LFO and envelope). The instrument includes an onboard sequencer and arpeggiator, features that contributed to its popularity for repetitive patterns and rhythmic synth lines.
The SH-101 was designed as a relatively portable and accessible synth, and it is notable for battery operation and a compact format. It was also sold with performance accessories such as an attachable modulation grip (depending on configuration). Over time, the SH-101 became a widely referenced example of early-1980s Roland monosynth design and is frequently associated with bass and lead roles in electronic production.
The SH-101 is often discussed alongside other monophonic analog synthesizers and bass-line oriented instruments from the same broad period:
