The Basics of Sound Synthesis — The Pro Audio Files
Another type of module frequently used to control other modules is the , or . An LFO is just like a normal oscillator, it can have any waveform and amplitude we specify, but it has a very low, sub-audio frequency, producing a very slowly oscillating signal generally used to control other modules within a synthesizer. For example, an LFO might move the volume level of a VCA up and down, creating a tremolo effect. LFOs are like little robots that turn knobs back and forth for you.

You can connect external audio sources – other synthesizers, mixers, guitars, and more – using the 1/4” inputs. The jacks accept either balanced or unbalanced cables. You can mix in the external audio sources with the MINIAK’s oscillators. The resulting combination is then sent through the MINIAK’s filters and effects. A special group of programs including vocoder programs exists just for use with the external inputs.
