Realtime Recognition Parameters

Realtime Algorithms differ a bit from ones that used in Offline Recognition. These topics describe the differences.

 

There is also a difference between the notes that are played when recognizing in Realtime and notes that are recorded into a MIDI file. Minimal Note Duration parameter is applied only to the recorded MIDI, because the note length is not yet determined when the note starts to play. For the same reason, all realtime notes are played at a constant volume (velocity).

 

RealTime uses its own algorithm of Pitch->MIDI processing. Minimal Note Duration is applied to the recorded MIDI notes, all other parameters from Pitch->MIDI Tab are ignored. MIDI file options are taken from MIDI Options dialog.

 

Selection of most realtime parameters is made directly from Realtime Module .

 

Noise Gate parameter sets an absolute cutoff for silent notes. All notes that are quieter than the Noise Gate are taken away.

 

It is always recommended to play with different recognition settings to achieve better performance.

 

Realtime Algorithms

 

Polyphonic - Sensors is similar to "Advanced Sensors" offline algorithm.

Polyphony determines relative cut-off for simultaneous notes. The higher the value, the more notes can sound at the same time.

 

Monophonic - Correlators is a monophonic algorithm that uses correlators. It has no additional setup.

 

Monophonic - Sensors is a monophonic modification of the Sensors algorithm.

Harmonic Filter allows fixing the situation when overtones are recognized as notes, but setting this parameter to a very high value can lead to almost all of the required notes missing.
