CHIPTUNE SYNTH

THE SID, RECREATED

ChipTune is a faithful recreation of the SID, the sound chip of the Commodore 64, made easily playable as a software synthesizer, with a few signature Morphoice effects on top. Its oscillators, noise generator and envelopes are bit-accurately modeled at the chip's original clock rate. The 6581's waveform output and output stage were matched to extensive measurements of an original SID chip. The filter is circuit-modeled for both chip revisions, the 6581 and the 8580.

ChipTune is an instrument you play from your keyboard or DAW like any other synth. It does not load or play SID files or C64 songs.

SOUND ENGINE

• Switch between the 6581 and 8580 chip revisions
• Triangle, sawtooth, pulse and noise waveforms, combinable like on the original chip
• Pulse width with built-in pulse-width modulation (rate and depth)
• Hard sync and ring modulation, with coarse and fine tuning
• Authentic SID ADSR envelope
• Multimode filter: low-pass, band-pass and high-pass, freely combinable, with cutoff, resonance and drive
• Separate filter envelope (ADSR) with positive or negative amount
• Glide, and pitch bend of ±12 semitones

PLAY MODES

SOLO is a true monophonic SID voice. Notes played back to back retrigger cleanly; overlapping notes glide. ARP is the classic chiptune chord arpeggio: hold up to four notes and they cycle in sync with your host tempo, at rates from 1/4 to 1/64 per pass. POLY gives you up to 16 voices, each its own SID voice.

SIGNATURE MORPHOICE EFFECTS

A Juno-style chorus, a vintage tape delay and the Morphoice signature DarkStar reverb/shimmer.
