Analog inspired parametrized digital drum synthesizer.

Basimiuls Iteritas is a parameterized digital drum synthesizer with its roots in the analog world.

At its heart it is a simple six oscillator additive synthesizer with adjustable waveform, harmonic spread and decay.

Adjustable attack, including a noise oscillator, is also included. These are summed and fed into an infinifolder for crunch and variety.

Tone Generation

Basimilus Iteritas uses six tonal and one noise oscillator in two configurations to generate sound. The SKIN setting is a basic additive synthesizer meant to simulate instruments that have modes that do not interact. The METAL setting modulates the oscillators by each other to simulate instruments that have
a lot of modal interaction. In the Basimilus Iteritas Alter, a LIQUID setting has been added, for those drippy type drum sounds. 

The first oscillator frequency is determined by the pitch input. The SPREAD control adjust the pitch (relative to the base pitch) of the other five oscillators. Each oscillator has an individual envelope that is controlled by the ATTACK, DECAY and HARM controls.

The noise envelope is also affected by the ATTACK knob. The oscillators are summed and then the ATTACK envelope is applied to the sum. This then feeds into the folder.

The folder is a threshold reflection folder with amplitude compensation and the ability to dynamically add more fold stages if another stage would affect the signal. At very high settings the fold will add in an exponentially decaying pulse at the local minima and maxima of the signal to add a gnarly buzz.

The final step is another envelope. This envelope is derived from the overall shape of the six oscillator envelopes. It adds back in the dynamics lost by folding so the output is remains punchy under the most extreme folding.

The Basimilus Iteritas Alter contains a few extra tricks - one being able to modulate between Skin, Liquid and Metal modes with CV, as well as Bass, Alto, or Treble ranges. This allows one to create patches in which the Basimilus performs as more than one drum sound, drastically changing in between hits.
