Basimilus Iteritas Alter Drum Synthesizer - 10HP

Noise Engineering Basimilus Iteritas Alter

The Noise Engineering Basimilus Iteritas Alter is a slimmer, updated version of the original. The module is essentially a complex drum voice comprised of six oscillators and a noise source. Additionally, the module makes use of three algorithms that influence how the oscillators interact; even better, each algorithm has a dedicated gate input for effortless activation. Skin mode is akin to classic additive synthesis, while Metal achieves much denser waveforms due to its cross-modulation of the oscillators. The final mode, Liquid, is true to its namesake in that it easily achieves wet, drippy percussive sounds. 

Using the pitch and spread controls allows users tote the fundamental and displace the other five oscillators across various ranges for intriguing timbral alterations. The module’s harm control affects each oscillator’s harmonic decay, meaning that their individual volume is adjusted in accordance with each distinct decay value. There’s also a built-in envelope with corresponding CV input and variable AD parameters, and a wavefolder that serves as the nexus for all of the Alter’s sound sources, and can be used to aid in the creation of complex, discordant percussion sounds.
