Sound engine and synthesis options
Spire has four multimode polymorphing oscillators, each with classic, noise, FM, AM, sync and saw-PWM modes. Each oscillator offers nine unison voices that can be spread across chords and octaves, which the developer says can imitate supersaw and hypersaw unisons.
The two filters can run in analogue or digital types, with named modes including Perfecto, Infecto, Acido, Scorpio and Combo. Shaper/Decimator, phaser, vowel, chorus/flanger, delay and reverb effects are built in.
