Cherry Audio has released Pentaphonic, a software synthesizer recreating the Gleeman Pentaphonic, a rare vintage instrument designed in 1981 by Bob and Al Gleeman. According to Monthly Mixing, fewer than 70 units of the original were produced, making it one of the rarest synthesizers.

The plugin reproduces the original’s hybrid architecture, combining digitally controlled oscillators with analog filters, while expanding features for modern players. Polyphony scales from mono to 16 voices, up from the original’s five, with a unison mode included. Cherry Audio added pulse-width modulation, a noise generator and oscillator sync, and expanded the modulation sections to two. The filter switches between 2-pole and 4-pole operation with keyboard tracking and a limiter.

Performance controls include velocity, channel aftertouch and polyphonic aftertouch. The instrument ships with a syncable arpeggiator, a 16×4 polyphonic step sequencer, a parameter animator and 22 built-in effects. Pentaphonic is available as VST, VST3, AU and AAX plugins plus a standalone app, priced at $59. A Translucent Preset Pack containing 100 presets is sold separately for $9.99.
