01Overview

Baervaag is built around a deliberately simple FM architecture: one carrier oscillator and one modulator. Klevgrand describes the design as FM synthesis for the masses, aimed at producers who want frequency modulation without a dense matrix of options. Each oscillator can move smoothly from a pure sine to a square wave, with pulse width modulation available along the way. The instrument also includes a set of 50+ presets created by professional musicians as starting points.

Oscillator Shaping and Envelope Control

Each oscillator has an XY pad. On the carrier, the X-axis controls pulse width modulation and the Y-axis controls the wave shape, moving between sine and square.

The modulator pad works the same way and adds a frequency multiplier button, which lets you set the modulator's pitch relationship to the carrier.

Each oscillator has its own ADSR. The modulator's envelope is set relative to the carrier's: when all of its sliders sit at the midpoint, the modulator follows the carrier envelope exactly. Velocity can modulate the FM feedback, filter, attack and volume, so how you play the keys changes the timbre as well as the loudness.

Effects, Wobble and Who It Suits

The FX and master section includes a delay, a chorus and a master output knob. Klevgrand describes the delay and chorus as high-quality.

A controllable wobble factor adds what the developer calls analogue unpredictability, giving sustained sounds some movement without extra modulation routing.

Because the signal path is compact, Baervaag suits producers who want to learn FM basics or sketch bass, lead and pad sounds quickly. It is available as a trial.
