Unknown 64 Pro is a single oscillator synth designed to recreate the "classic" Commodore 64 sounds.

Features:

• Single oscillator
• 4 waveforms (triangle, pulse, saw and noise).
• A filter envelope with 3 filter types (lowpass, bandpass and hipass).
• A pitch envelope / pulsewidth envelope and volume envelope.
• Every Envelope can be inverted and has 13 different curves.
• A ring-modulation oscillator or a ring-modulation BPM LFO.
• A BPM LFO for the Pulsewidth, cutoff and oscillator pitch.
• 3 big sequencers for creating the real c64 arps and percussions:
  • One is used for the octave and notes.
  • One only for octaves.
  • One for the waveforms.
• All 3 sequencers are BPM sync with speeds from 1/16 to 1/128. They can be ended at every step or looped.
• Vibrato, bitcrusher, MIDI learn and panner.
• Envelope restart / pickup.
• 128 presets.
