Patent number: 9136962Abstract: A frequency characteristics control device of a mixer mixes a first audio signal and a second audio signal inputted to the mixer. In the frequency characteristics control device, a characteristics detection section detects a first frequency characteristic of the first audio signal and a second frequency characteristic of the second audio signal. Based on the first and second frequency characteristics, a removal band detection section detects a removal band in which a level of the first audio signal is higher than a level of the second audio signal. A filtering process section performs a filtering process on the second audio signal so as to attenuate a component of the second audio signal in the removal band.

Patent number: 8373054Abstract: When musical performance data is input to the electronic musical instrument in accordance with user's operation for musical performance, the electronic musical instrument detects a chord in accordance with the input musical performance data at the defined timing T3 at which the chord detection timing ends. On the electronic musical instrument, furthermore, the application of the detected chord to the musical performance is instructed by user's pedal (foot switch) operation of turning off the pedal. In a case where the instruction to apply the chord has been already accepted at the chord detection timing T3 or in a case where the instruction to apply the chord has been accepted by user's pedal-off operation at a point in time (Tpf) situated between the chord detection timing T3 and the time limit T4, the detected chord is to be applied to the musical performance.Type: GrantFiled: July 12, 2011Date of Patent: February 12, 2013Assignee: Yamaha CorporationInventors: Akihide Hara, Yasuhiro Kawano

Patent number: 7432437Abstract: An arpeggio playing apparatus comprises an arpeggio pattern storing device, an arpeggio pattern readout device and an arpeggio tone processing device. The arpeggio pattern storing device stores at least one arpeggio pattern pair including a regular version pattern and an accentuated version pattern for automatic arpeggio performances. When there comes a key-on event representing an arpeggio designation and a key-on velocity, the arpeggio pattern readout device reads out, from the arpeggio pattern storing device, the regular version pattern when the detected velocity is less than a predetermined threshold value, and the accentuated version pattern when the detected velocity is not less than the predetermined threshold value. The arpeggio tone processing device automatically plays arpeggio based on the arpeggio designation by the key-on event and according to the arpeggio patterns of the read-out versions.Type: GrantFiled: September 21, 2007Date of Patent: October 7, 2008Assignee: Yamaha CorporationInventors: Yoshihisa Ito, Yasuhiro Kawano, Masao Ishibashi

Patent number: 7370204Abstract: By a program process, CPU 31 embeds a watermark data into a waveform data stored in wave memory 41a. The program includes a step for detecting a characterizing part (attack part and loop part) of a waveform data that represents a waveform of a musical tone where the characterizing part represents characteristics of the musical tone, and a step for embedding a watermark data into a part of the waveform data excluding the detected characterizing part. Further, CPU 31 can also extract the watermark data by a program process including a step for detecting the characterizing part and a step for extracting the watermark data embedded in a part excluding the detected characterizing part. Thus, from waveform data including a watermark data, natural musical tones can be reproduced without deteriorating the characteristics of the musical tones at the time of reproduction.Type: GrantFiled: February 11, 2003Date of Patent: May 6, 2008Assignee: Yamaha CorporationInventor: Yasuhiro Kawano
