Basimilus Iteritas Alia is a parameterized digital drum voice with its roots in the analog world. At its heart, the BIA is a simple six-oscillator additive and FM synthesizer with waveform, harmonic spread, and envelope controls. An adjustable noise oscillator and an extreme take on a wavefolder round out its synthesis abilities. Its straightforward controls make sound design fun and performable: create sub-shaking kicks, snares, hats, and unique drum hits with just a few tweaks.

BIA is a classic percussion module but you'll be blown away by how much more it can do. Use it for leads, basslines, or build a whole drum kit with some external CV. Plus, the envelope output means you can use the BIA for shaping and modulating other parts of your patch.

Basimilus Iteritas Alia is the successor to the Basimilus Iteritas Alter. It was developed to sound nearly identical, with added features and new firmware-swapping capabilities.

Basimilus Iteritas Alia is part of the Alia DSP platform. A simple USB connection lets you swap between a variety of oscillator firmwares for free. Try them now at the Firmware Swap app.
