Before a MIDI recording can be transcribed, the notes’ beginning and ending times must be quantized to coincide with beats or a subdivision of beats based on the time signature.
- To quantize a recording, select the notes you want to quantize and choose Quantize from the Edit menu. If no notes are selected, all notes in the recording are quantized.
- To work with a different quantization rhythm, choose a value from the Quantization Value submenu in the Edit menu. This value determines the division of time for snapping notes to an exact time location.
- If there are triplets in a recording, turn on the Allow Triplets option in the Edit menu before quantizing.
Note that whenever you copy notes from a MIDI recording for transcription, they are automatically quantized to the selected quantization value.
