What it does

Poly M is XILS-lab's emulation of the Polymoog, built on its top-octave-divider oscillators. The developer spent more than two years analysing the original and says it "excels in warm, wide modulated sounds and fat basses", while opening up parameters the hardware did not expose.

Divide-down oscillators: two aliasing-free top-octave-divider oscillators, one sawtooth and one square, with per-note pulse width modulation.
Chip modelling: 71 emulated chips covering the mixer, VCA, envelope, 12 dB filter and PWM circuits.
Per-note filters: a 12 dB filter on each note, modulated by its own ADSR envelope.
Ladder filter: a self-oscillating 24 dB Moog ladder filter with a zero-delay design.
Acoustic filters and resonator: nine fixed acoustic filters (strings, piano, organ, harps, funk, clav, vibes, brass and vox) and a resonator bank of three parametric filters in 6 or 12 dB, low-pass, band-pass or high-pass modes.
Modulation: a nine-slot modulation matrix, a monophonic ADSR envelope and three tempo-syncable monophonic LFOs, with every parameter MIDI-controllable.
Effects and extras: vintage-style phaser, reverb, delay and chorus, an arpeggiator with cycled modulation and mutes, and 440+ presets in a multi-criteria preset manager.

This is version 1.5.4, with NKS support. A 15-day time-limited demo licence is available.

When to use it

Poly M is the pick for the specific late-1970s Polymoog sound: divide-down strings, organ, Vox Humana-style choirs and wide, modulated pads. Compared with Diva, it covers one unusual architecture rather than several voice-per-note polysynths, and its fixed acoustic filters give it a sound closer to a string machine than a typical analog polysynth. It is far narrower than Vital or Pigments 7, which cover modern wavetable and hybrid synthesis, and its monophonic envelope and LFOs make it less suited to complex per-voice movement. It is also one of the cheaper XILS-lab synths at its current sale price.

Best for: vintage Polymoog strings, organ and vox patches, warm modulated pads and fat basses.
Genres: synthpop, new wave, soul, electronic and cinematic music.
Look elsewhere if: you need a flexible modern synth (Vital or Pigments 7) or a classic voice-per-note analog polysynth (Diva).
