Pros & Cons

👍 Pros

  • Delivers authentic SH-101 sound powered by Roland’s Analog Circuit Behavior (ACB) technology for classic analog tones.
  • Enables crafting all-new sounds through powerful oscillator drawing, oscillator chop, and riser tools for creative sound design.
  • Offers versatile voice modes including mono, poly, unison, and chord modes, with four-voice polyphony for varied musical expression.
  • Features a hands-on panel with familiar synth controls, allowing for instant sound shaping and live performance tweaks.
  • The D-Motion feature allows control of pitch, mod, and other parameters by physically moving the S-1, adding a unique performance element.
  • Includes a 64-step sequencer and 64 patterns, facilitating on-the-spot song creation and arrangement.
  • Equipped with class-compliant USB-C audio/MIDI interface, requiring no drivers for easy integration into a digital setup.
  • Comes with square, sawtooth, sub, and noise oscillators, providing a fundamental palette for synthesis.

👎 Cons

  • The "micro polysynth" designation suggests it might have a compact form factor, potentially leading to smaller controls or fewer dedicated buttons than larger synths.
  • Four-voice polyphony, while present, may be limiting for complex chord progressions or rich pads compared to synths with higher polyphony.
  • While inspired by the SH-101, the digital nature of ACB technology may not satisfy purists seeking only true analog hardware.
  • The 64-step sequencer and 64 patterns, though versatile, might not be extensive enough for composing entire tracks without external sequencing.
  • The D-Motion feature, while unique, might require practice to master for precise control during live performance.
