Source: a console-style sound chip playing a fast three-note arpeggio. Each note is a pulse-wave voice (duty cycle 12–50 %) with a soft triangle channel one octave below, as on classic 8-bit hardware.
Body: the pulse has strong odd harmonics; a gentle low-pass keeps the top end crisp but not piercing. The last note rings longer and closes the phrase.
Envelope: 1 ms declick ramp, a short hold, then an exponential-feeling decay per note (about 60–90 ms), with the final note decaying 2–3 times longer. Notes are evenly spaced like a tracker row clock.
Lo-fi: the summed signal is quantized to a few amplitude levels (bit depth) and a faint high-passed noise tick on each note start gives the DAC-like grit; a DC blocker and an overall fade-out end the sound cleanly.
Variation: the chord shape (major, minor, fifth, octave), pitch, speed, duty cycle, bit depth and brightness.
