Debel Iteritas Alia is a hybrid additive phase-modulation voice inspired by classic and experimental synth sounds from across the decades. Three synthesis algorithms range from classic FM plucks and basses to all-out additive anarchy. DIA features a two-parameter envelope with a huge range of shapes and timing, making it easy to dial in the exact sound you want. With CV over every parameter, a dedicated envelope output, and an absolutely massive timbral range, Debel Iteritas Alia is a powerhouse synth voice in a compact package.
On paper, Debel shares some similarities with the Basimilus and Manis, but it has an entirely new sonic character and complements the sound of the other Alias very well. Its versatile envelope makes it perfect for a variety of sounds: on the shorter side, create FM plucks and bells that are perfect in a house or techno patch. Or, use longer settings with big attacks to create swells and long gestures in an ambient patch.
Debel was designed for experimentation, and has a big range. It was also designed to be performable: despite being based around a traditionally complex PM structure, its parameters were carefully tuned to perform predictably and fun to use in a jam or a performance. It’s a great choice as the main melodic voice in dance-oriented system, an experimental source in a sound-design rig, and since it’s an all-in-one voice it’s a fabulous option for a compact system: just add a trigger/CV sequencer and it’s ready to go.

Octave adjusts the levels of the additive oscillators, Detune changes the
frequency of the modulating oscillator, and Index adjusts the amount of
modulation. Grit adds some saturation and distortion as the parameter is turned
up. The Time parameter adjusts the overall time of the attack/decay envelope,
and the Shape parameter adjusts the ratio of attack versus decay within that
The Taco/Nacho/Diablo switch selects which algorithm is used to create the
sound. All algorithms use a unique PM structure: four operators generate the
sound, and each operator in turn has four oscillators that are balanced with the
Octave control. Taco uses a 2x2 algorithm, Nacho uses a linear four-operator
structure where each oscillator modulates the next in series, and Diablo adds a
pitch envelope to Nacho for extra impact.
