xoxos has followed up Cube Breath with Breath Cube which employs the 'pop music generating' engine of Cube Breath and adds a 3-band synthetic voice to "challenge your listening skills".

Breath Cube was created using SynthEdit and runs as a standalone with the included SAVIHost application or as a VST plug-in.

The Breath Cube GUI features artwork by Shane Sanders.

Breath Cube is free, but a remittance of $10 is suggested for wealthy people who enjoy it.
