Patent number: 5973253Abstract: An electronic musical instrument for conducting an arpeggio performance of a stringed instrument capable of readily producing a pattern for the arpeggio performance as one likes, and also of conducting the arpeggio performance which is perceived as being less musically incompatible even if the player makes a mistake during a performance of allocating of pitch at the time of the arpeggio performance. A pattern for the arpeggio performance is produced adopting such a rule that a time axis is renewed when all the strings become silent, or such a rule that it is regarded as having the same timing while a pedal is kept depressed. When the arpeggio performance is conducted, even if a mismatch occurs between the string of the pattern and the string played for a pitch allocation, those strings are compulsively allocated together.Type: GrantFiled: October 7, 1997Date of Patent: October 26, 1999Assignee: Roland Kabushiki KaishaInventor: Takashi Hirata

Patent number: 5852438Abstract: For the sake of improving the operability in edits of audio and video signals in a video editor, the video editor of the present invention is constituted in such that at least two types each of audio and video signals are inputted, and levels of the audio and the video signals inputted are controlled in response to the operations of faders. The video editor is provided with a first fader; a second fader; and a control means for controlling simultaneously a ratio of composition in two types of video signals inputted with levels of two types of audio signals inputted in response to the operation of the aforesaid first fader, and only the levels of the audio signals inputted being controlled in response to the aforesaid second fader.Type: GrantFiled: November 29, 1995Date of Patent: December 22, 1998Assignee: Roland Kabushiki KaishaInventors: Mizuo Tomizawa, Atsushi Tomita, Hironori Mikami, Satoshi Seto

Patent number: 5811707Abstract: An effect adding system for use in Karaoke performance applications is provided which, when one person sings, singing with different height from that of the actual singing, or singing with different timing from that of the actual singing, is automatically carried out to yield, in part, the same effect as if a chorus, duet, round, or the like is performed by a plurality of persons. In one embodiment, the effect adding system accomplishes this by means of pitch conversion and/or delay of the aural input signal in response to pitch conversion and/or delay information deriving from stored performance information for a particular musical composition.Type: GrantFiled: June 5, 1995Date of Patent: September 22, 1998Assignee: Roland Kabushiki KaishaInventors: Ikutaro Kakehashi, Tsuneo Higuchi

Patent number: 5751771Abstract: The present invention provides a waveform data compression apparatus which can express waveform data by a small amount of compression data obtained by compressing the aforesaid waveform data, and a waveform data expansion apparatus which can reproduce the compression data produced by the aforesaid waveform data compression apparatus to obtain the original waveform data. The. waveform data compression apparatus interpolates waveform data of addresses before and behind the waveform data of an objective address in a block to be processed to acquire interpolated data of the objective address to be processed, and uses difference data between the interpolated data and the waveform data of the objective address to be processed, thereby compressing the waveform data. The waveform data expansion apparatus operates to perform reverse process to that performed by the waveform data compression apparatus.Type: GrantFiled: June 5, 1995Date of Patent: May 12, 1998Assignee: Roland Kabushiki KaishaInventors: Masaaki Katsumata, Satoshi Kusakabe

Patent number: 4633750Abstract: A key-touch value control device for an electronically operated musical instrument including a series of keys, wherein the state of each of the keys is detected to produce a succession of key-state signals each indicative of one of the key-on state, key-off state and key-fly state of the key. In response to each of the key-state signals, a key-touch value signal is produced which is variable with the velocity at which the key is being depressed toward the key-on state and which is representative of the volume of the sound to be produced after the key has reached the key-on state.Type: GrantFiled: May 17, 1985Date of Patent: January 6, 1987Assignee: Roland Kabushiki KaishaInventor: Tadao Sakai
