Vocals, bass lines, hooks - how to get a genuine 4-channel chip sound in any DAW, and why a bitcrusher alone will never get you there.
The sound of late-80s handheld and console music was not a style choice - it was a hardware budget. A typical sound chip gave composers about four channels: two pulse waves with a handful of duty cycles, one small wavetable voice, and one noise generator. Tuning stepped in coarse increments because pitch lived in a small frequency register. Every classic soundtrack you remember was written inside those walls.
That means chiptune character comes from five specific things: pulse waves with switchable duty cycles, a low-resolution wavetable (think 32 samples at 4 bits), LFSR noise for percussion and texture, stepped tuning from the frequency register, and arpeggios - the trick composers used to fake chords when they only had one channel to spare.
Most producers reach for a bitcrusher and stop there. A bitcrusher reduces bit depth and sample rate, which adds grit and aliasing - useful, but it only degrades the audio you already have. Your vocal gets crunchy. It does not become a chip voice.
Resynthesis goes the other way: the plugin listens to the pitch and envelope of your audio, then replays that performance on modelled chip channels. The output is not your waveform with damage on top - it is a genuine pulse-and-wavetable voice following your line, with the stepped tuning and channel limits of the original hardware. That is the difference between "lo-fi vocal" and "my hook is now playing on a handheld."
Resynthesis needs a monophonic source: a lead vocal or vocal double, a bass line, a single-note hook, a mono synth part. Chords, full mixes and drums will make any pitch tracker chase partials and warble - that is physics, not a bug.
Insert the resynth stage and let it track the take. In TALLBOY that is the CHIP 4CH cartridge - the 4BIT CHOIR preset does the classic sustained vocal-to-chip trick in one move. Pick a pulse duty cycle for the tone: thinner duties read as "retro lead," wider ones sit closer to square-wave bass.
Sync the arp to your project tempo - 1/16 UP across two octaves is the classic move, CHRD mode fakes harmony from a single line the way chip composers did. Then add decimation to taste: modest bit reduction for sheen, hard rate divide with jitter for full cartridge dirt.
Fully wet, the chip voice is a new instrument playing your melody. Blended 20-40% under the original, it is an 8-bit double that makes a hook feel twice as wide. Flip the arp to a different pattern and the same take becomes a counter-melody.
For anything without one clear pitch, skip resynthesis entirely and use straight decimation: bit reduction, sample-rate divide, and a dark post filter. In TALLBOY, eject the CHIP 4CH and ARP cartridges and run CRUSH ROM alone - 1 to 16 bits, rate divide 1-64 with jitter, post filter down to 540 Hz. That is the honest way to get chip-adjacent drums, and it doubles as a general-purpose lo-fi tool on sends and buses.
Bitcrushing degrades; resynthesis rebuilds. If you want audio that sounds like it is playing on a chip rather than through one, you need pitch-tracked resynthesis with real channel modelling - pulse duties, a tiny wavetable, hardware noise, stepped tuning, and an arp. That is exactly what TALLBOY does for $20, one-time, no subscription, no iLok, on macOS (VST3, AU, AAX) and Windows (VST3).
The TALLBOY page has A/B audio of one vocal, one synth and one drum loop through the shipping presets. Free demo, no email required.
