Arpeggiator Note Range Correction for Timbre-Suitable Playback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing arpeggio production devices produce unsuitable timbres for bass sounds, impairing musicality due to limited sounding ranges.
Innovation Solution
An arpeggiator with automatic performance and sound range correction features that adjust note numbers to fit within designated sound ranges, ensuring appropriate timbres for arpeggios.

Engineering Contradiction Analysis
1Adaptability or versatility
If the arpeggio production device outputs arpeggio sound according to pitch information of a key being pressed, then the arpeggio can be played freely across the keyboard range, but the timbre becomes musically unsuitable for bass sounds when keys outside the designated sound range are pressed
Solution Approach 1:
The system pre-establishes sound range settings for each timbre type before arpeggio playback. When a key is pressed, the system proactively checks whether the note number falls within the designated sound range and automatically corrects it if necessary, preventing timbre mismatch before it occurs
Solution Approach 2:
The system implements a feedback mechanism where the note number input by the performer is continuously monitored against the designated sound range for the selected timbre. When the note number falls outside the acceptable range, the system automatically feeds back a corrected note number that falls within the appropriate range, ensuring timbre consistency

AI summary
In a synthesizer 1, the highest note number is set from the allowed Oct width and the lowest note number of a sound production part in a setting table 11e, and if the note number of an Arp note memory 12b is not between the lowest note number and the highest note number, the note number of one octave unit is added to or subtracted from the note number of the Arp note memory 12b. Consequently, the note number of the Arp note memory 12b is corrected to the pitch range between the lowest note number and the highest note number, and thus can be corrected to the sound production pitch range of the timbre of the sound production part, and arpeggios can be outputted using sounds that are more appropriate for an instrument of said timbre.
