New Buchla-Format Algorithmic Oscillator is like Mutable Instruments Plaits on Steroids

1979 has introduced the Algorithmic Oscillator (AO), a Buchla-format VCO based on Plaits by Mutable Instruments.

The successor to the 1979 DAO, the AO has more knobs, more parameters, and more I/O than the DAO, plus features not available on the original Plaits module.

The company calls the AO “an ideal standalone voice module for small Buchla systems.”
