Noise Engineering Basimilus Iteritas Alter

The Basimilus Iteritas Alter from Noise Engineering is the improved edition of their famous original. It is a complex drum voice created using six oscillators and one noise source for additive synthesis, with various algorithms deciding on how they modulate, interpolate and combine. In Skin mode, it uses a basic additive synthesizer technique that simulates instruments with less complex overtones. The Metal setting starts adding in cross-modulation between the six oscillators, for much denser and complex waveforms. A Liquid mode has been added to the Basimilus Iteritas Alter for more drippy type drum sounds. 

The fundamental of the six oscillators is controlled by the Pitch knob and CV input. The Spread control displaces the other 5 oscillators across a wider range for more timbral variation. A built in envelope has variable Attack and Decay, along with CV inputs. The Harm control decides the harmonic decay of each of the oscillators, allowing different decay values to adjust the volumes of the six oscillators in a pattern rather than all using the same envelope. 

All sound sources are summed together before they are routed into a wavefolder. It uses a threshold reflection folder, which bends waves back when they reach a specific volume threshold. This provides lots of in-harmonic character to the sounds, making it great for complex non-tonal drum sounds. 

In the Alter edition, there are now gate inputs for modulating between the Skin, Liquid, and Metal modes, as well as Bass, Alto, and Treble ranges. This feature now allows one to make drastically different drum sounds from hit to hit, giving the illusion of many more drum modules in the patch.
