What Is Playback Timing? Original vs Linear

What Is Playback Timing? Original vs Linear

When you turn a live performance into sheet music, something interesting happens: the notation quantizes your performance into neat note values (quarter notes, eighth notes, etc.), but the original performance had subtle timing variations – a slight rush into the chorus, a ritardando at the end, micro-timing that gives the music its feel. The question is: should playback follow the strict, quantized notation, or should it preserve the timing of the original performance?

This is what playback timing controls. Most notation software uses strict (linear) playback by default, but software that works with audio recordings can offer both options.

Two Approaches to Playback

Original Timing

Original timing preserves the performance feel. Each note plays at the moment it actually occurred in the recording, not at the mathematically exact position implied by the notation. This means expressive pushes and pulls, tempo fluctuations, and micro-timing details all come through during playback.

Original timing is especially valuable when the score was created from an audio recording. The notation shows clean, readable rhythms, but playback retains the human performance quality. If the original audio is also synced to the notation, you can hear both the real recording and the MIDI playback tracking the same timing.

Linear Timing

Linear timing plays notes exactly as written, using the tempo marking in the score. There are no expressive variations – every quarter note gets exactly one beat, every bar is exactly the same length. This is useful when:

  • You want metronomic, “click-track” playback for practice.
  • You’ve simplified rhythms and want playback to match the cleaned-up notation, not the original micro-timing.
  • You’re sharing a score and want consistent, predictable playback for the reader.
  • The score was entered manually (not from a recording), so there’s no original performance data.

When Each Mode Matters

For performance study, original timing is often better – it preserves the musical phrasing that makes the piece interesting to listen to and learn from.

For sight-reading practice or rehearsal, linear timing can be more useful – a steady tempo makes it easier to read along and stay in time.

For editing, switching between the two modes helps you verify your notation: if the score sounds right in linear mode, the note values are correct. If it sounds right in original mode, the score captures what was actually performed.

Audio Sources and Timing Data

From Audio Recordings

When a score is created from an audio recording, each note can carry timing data from the original performance. This makes original timing possible. It also enables synced audio, where you can follow the score while listening to the real recording.

From MIDI Input

MIDI recordings also carry performance timing: velocity, note duration, and tempo variations. When a score is created from MIDI, the software may let you choose which aspects of the original timing to preserve – tempo variations, beat timing, or both.

Manual Entry

If the score is created entirely by manual note entry, there is no performance data. In this case, only linear timing is available, since there’s no “original” to replay.

Audio Time-Stretching

When switching from original to linear timing in a score that has synced audio, the audio needs to be time-stretched to align with the strict notation timing. This required processing can take a moment. Software that supports this typically offers a quality trade-off: a fast mode for quick previews and a higher-quality mode for final playback.

How ScoreCloud Handles Playback Timing

Both ScoreCloud Songwriter and ScoreCloud Studio let you switch between Original and Linear timing modes in the playback settings. The controls and options are the same in both apps. For songs created from audio, you also get time-stretch quality options (Fast or Best). For MIDI-sourced songs, you can independently enable or disable tempo variations and beat timing.

If you view the Analysis Details window (under the View menu), you can see beat timing percentages – this shows how the original performance’s timing maps to the notated beats, and helps you understand why certain passages sound different between the two modes.

Frequently Asked Questions

What is playback timing?

Playback timing controls whether a score plays back with the expressive timing of the original performance (original mode) or with strict, metronomic timing based on the written notation (linear mode).

When should I use original timing vs linear timing?

Use original timing when you want to hear the performance feel – phrasing, rubato, micro-timing. Use linear timing when you want strict, steady playback for practice, editing verification, or when the score was entered manually.
