xoxos has released Perfecto, a freeware virtual analog synth VST plug-in for Windows PC.

Perfecto has two relatively uncommon features:

1. two audio oscillators cross modulate via pitch (fm) and phase (pm).
2. pitch to user-scale algorithm that can be used for arpeggio effects.

Note: Perfecto’s oscillators are “unimproved,” with no antialiasing or other usual amenities and pitch or phase modulation of the oscillators uses tons and tons of cpu.

Perfecto features

• Oscs (4 voices of poly) - Sine, saw, tri and square waveforms, Key (syncing oscillators to NoteOn events), Octave, Tune and Portamento.
• LFOs - Sine, saw ramp, square and triangle waveforms, synced to key or free running.
• Scale - main pitch bus is snapped to user-input scale.
• Filter (H/L/B/R) - When the filter tracking mode button is lit, the filter’s cutoff tracks whatever is coming out of the scaler instead of the played keyboard note.
