Fors Glänta

Fors Glänta v1.1 [Max for Live]

Glänta is a synthesizer with a simple structure that puts focus on the fundamentals of FM synthesis with a carefully crafted 2-operator core. From years of expertise and obsession with FM synthesis, Glänta extends established concepts with unique twists that are powerful yet easy to use.


  • 2-OP FM Engine
  • Flexible FM ADSR
  • Regular Amp ADSR
  • with stereo phase modulation,
  • pitch-relative unison,
  • dynamic bipolar feedback,
  • cross-modulation,
  • and polyphonic note slide.
  • Up to 16 voices of polyphony.

Power of 2

Glänta puts focus on the fundamentals of FM synthesis with a 2-Operator structure that lets you sculpt a myriad of sounds with ease, this is FM done right to its very core, with extended functionality that expands the repertoire of 2-OP algorithms.


Each FM oscillator in Glänta has dynamic self-modulation, a type of feedback that is bipolar and frequency-compensated. This allows even a single oscillator to achieve saw- and square-like waveshapes that are consistent and alias-free across the whole pitch range.

Envelopes made for FM

The modulator envelope in Glänta is made with FM in mind. By extending the standard ADSR envelope with adjustable start- and end-levels, the FM envelope is streamlined for getting the timbral modulation just right. With a logarithmic attack and exponential decay, the modulation and dynamics sound natural and snappy.

Stereo Modulation & Unison

The stereo mode puts the modulation itself in a phase-shifted stereo alignment which widens the sidebands, creating an FM-based stereo effect. On top of this the pitch-relative unison mode adds two oscillators, one above and one below the fundamental for anything from slight chorusing to harmonic layering.
