What synthesizers did you use for the audio track?

In order of appearance:

• Intro: Bass guitar (plucking along different lengths of the string)
• Chord: supersaw (with all-pass filters), transitioning from equal temperament to just intonation and back
• Section 1: FM synth (with all-pass filters), with ratio between modulators being modulated causing the beating
• Section 2: another supersaw, first filtered with a resonant low-pass (cutoff modulated), then filtered with a bit reducer (low-pass cutoff still modulated)
• Section 3: everything + the synth for the next section
• Ending: Electric piano synth in just intonation passed through distortion (slowly being removed) and an all-pass filter
