Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
83 words
An electronic musical instrument comprising means for generating an input digital datastream representing a sequence of musical sounds, reference sequence means for providing reference sequence data representative of background harmonic musical sounds corresponding to said input datastream, control means for receiving said reference sequence data and said input datastream so as to provide dynamic correction to said datastream over a variable time delay, and sound generator means for providing dynamically corrected audio output sounds which are dynamically corrected over said variable time delay.
Claim 2
Dependent Claim
83 words
An electronic musical instrument comprising means for generating an input digital datastream representing a sequence of musical sounds, reference sequence means for providing reference sequence data representative of background harmonic musical sounds corresponding to said input datastream, control means for receiving said reference sequence data and said input datastream so as to provide dynamic correction to said datastream over a variable time delay, and sound generator means for providing dynamically corrected audio output sounds which are dynamically corrected over said variable time delay.
Claim 3
Dependent Claim
46 words
The instrument as in claim 1 including means for harmonically analyzing said reference sequence data and means for determining if the input datastream corresponds to a chord tone together with a note that is in the chord of the background music from the harmonic analyzer means.
Claim 4
Dependent Claim
21 words
The instrument as in claim 2 including means for playing the note immediately if the played note is a chord tone.
Claim 5
Dependent Claim
31 words
The instrument as in claim 2 including means for determining if the played note is a scale tone (if not a chord tone) and means for playing the scale tone immediately.
Claim 6
Dependent Claim
14 words
The instrument as in claim 4 including means for computing the nearest chord tone.
Claim 7
Dependent Claim
25 words
The instrument as in claim 5 including means for scheduling the scale tone to be corrected to a chord tone over a predetermined time delay.
Claim 8
Dependent Claim
17 words
The instrument as in claim 6 wherein the nearest chord tone corresponds to the existing scale tone.
