Dynamic FM Synthesizer

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.

All sounds in the video are made only with Glänta, using no effects.

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.
