Why a correctly notated Guitar Pro riff sounds wrong

A familiar collection of fret numbers can hide a wrong duration, pickup, rest, tie, or tuplet. Loop one bar at half speed with the metronome and count the smallest repeated subdivision. If the attack points do not line up before tone and effects are considered, repair the rhythm first.

Check whether notes that should stop are tied, whether short rests were omitted, and whether a dotted or triplet value was entered accidentally. Also inspect triplet feel and swing settings at score level; they can alter otherwise straight-looking eighth notes across an entire passage.

Guitar Pro can interpret a stringed track with options such as Auto Brush and Auto Let Ring. Auto Brush offsets notes in a chord to imitate a pick moving across strings, which is useful for strumming but can smear a tight unison or chord stab. Auto Let Ring can sustain strings that the original riff stops deliberately.

Turn those behaviours off while diagnosing, and select a neutral playing style. If the groove immediately tightens, re-enable only the behaviour the part actually needs. A written brush direction is better than a global automatic brush when only selected chords should be rolled.

Palm mute, let ring, staccato, dead notes, ghost notes, accents, pick strokes, hammer-ons, slides, and ties all affect attack or sustain. A copied beat may carry a technique you cannot easily spot at normal zoom, and two instructions can fight: let ring against staccato, for example, or a tie across a note meant to be re-picked.

Duplicate the test bar, remove its techniques, and add them back in families. Start with attack and pick direction, then muting and duration, then expressive effects. Playback after each change; this is faster than toggling several controls and guessing which one mattered.

The score may contain correct pitches on implausible strings. Notes that should ring together cannot always do so when Guitar Pro assigns them to one string, while a slide or legato phrase can become impossible if successive notes jump between strings. Inspect the tablature fingering rather than judging only the stave.

Shorten written or interpreted sustain where the player lifts a finger, and use rests or staccato when silence is musically important. For power-chord riffs, check whether all chord tones should attack together or whether a deliberate downstroke spread belongs in the sound.

RSE and MIDI can make the same notation feel different, but switching engines does not repair an incorrect rhythm or contradictory technique. Once the neutral bar behaves, choose the engine, instrument preset, pickup, effects, and humanisation that suit the context, then compare at matched volume.

Avoid judging a soloed distorted guitar as though it were the final mix. Restore bass and drums, check whether competing frequencies obscure attacks, and reduce excessive gain or ambience before adding more accents. If one file alone behaves strangely, compare the affected track against a new blank score to isolate file-specific settings.
