The Heisenberg is a software simulation of a digital synthesizer implementing phase modulation. It is mono-timbral, can be set to monophonic or polyphonic mode and its voice can be multiplied in unison mode. Its sound sources include four operators that can modulate each other’s phase using a four by four modulation grid that allows 65535 different algorithms. Each operator can produce 49 different waveforms. A multi-mode, multi-order resonant filter lets you further sculpt the raw sound. It also provides two sophisticated LFOs and four envelope generators to modulate operator pitch and amplitude, as well as filter cutoff frequency. You can further modulate operator amplitude and filter cutoff frequency with note velocity. You can also tune its pitch and glide it between notes. You can play the Heisenberg through note tracks and its note input connector, even simultaneously. Thanks to its phase modulation capability, the Heisenberg excels at producing a wide range of clear, bright and evolving sounds with complex attack transients, both imitative and synthetic. Using self modulating operators, you can also produce noise for realistic percussion sounds. Note: Due to its complexity, the Heisenberg can use a lot of processing power from the sound engine.
