Octaver adds down/up voices alongside Dry. Undertone has an analog-style monophonic character rather than guaranteed polyphonic chord tracking. Quiet notes, dense chords, and low registers can lead to rough tracking.
Guitar Synth analyzes audio to drive synthetic timbres. Some voices follow the dominant note; some analyze several harmonic groups. This is not MIDI output or a sampled instrument library. Tracking has note-range and response limits that need listening. Evaluate each voice rather than calling all of them polyphonic or all of them monophonic.
Chiptune creates a pulse wave: Duty colors the pulse, Octave transposes it, and Blend sets the mix. Lattice follows one note and creates a root/major-third/fifth/octave pattern; it is not a general MIDI chord reader. Stutter repeats a short buffer using Division/BPM, and Gate sets the audible part of the slice. This Gate is not a noise-gate threshold.
A clean signal before drive or ambience is usually easier for a tracker to analyze. Violin or brass sounds are not claims of exact acoustic-instrument reconstruction. Acoustic Simulator likewise produces an acoustic-style character, rather than turning a pickup into an actual acoustic-guitar microphone.
