Rob Hubbard · C64 SID Chiptune · 1985
fast. 140bpm. tight + bright. lots of arpeggio gymnastics because the SID had only 3 voices — composers used arpeggio to FAKE chords (rapidly alternating root + 3rd + 5th to imply harmony). that's the chip sound: implied polyphony via fast arpeggio.
C64 game soundtracks
the Commodore 64 (1982) had the SID 6581 sound chip — 3 oscillators, ring modulation, programmable filter. rob hubbard + martin galway were the chip's greatest composers. they wrote video game soundtracks where the SID was the WHOLE band — drums (white noise channel), bass (one square voice), lead (the other voices) + filter modulation as the only 'effect.' an entire orchestra on one chip with 64KB of RAM.

the SID lead — fast 16th-note pentatonic minor
C64 SID synthesis with a fast 16th-note pentatonic minor lead at 140bpm. tape on for warmth (1985 SID through a CRT TV's audio path picked up tape-like warmth from the analog circuitry).

the SID's lesson: LIMITATIONS create style. 3 voices forced composers to use arpeggio as harmony. white-noise-only percussion forced creative drum programming (the noise channel doing kick AND snare AND hi-hat by changing its envelope). 64KB of RAM forced compact composition. limitations weren't problems — they were the GENRE. when you work in any restricted format (chip music, modular synths, single-machine setups), embrace the limitations as creative direction. the alternative — full DAW + infinite plugins — gives you everything and a sound that's nothing specific.
trying to make chiptune with modern multi-voice synths. the genre's MAGIC is that everything happens within 3 voices. as soon as you add a 4th voice (extra pad, sub bass, etc.), it stops being chiptune and starts being 'electronic music with chip elements.' commit to the constraint. also: most chiptune plugins ignore the SID's specific filter behavior (the famous 'broken' lowpass that some C64 revisions had). real SID has dirty + glitchy character. clean digital emulations miss the magic.
