A common methodology of learning to play a particular musical instrument or to emulate its performance in a recorded piece of music is to play along with the recorded piece of music attempting to replicate the performance of the particular instrument as closely as possible. To facilitate this process, it is often desirable to single out the particular instrument for a user to follow. Especially in the early stages of learning a new piece of music, it is desirable for the user to hear both the instrument that is being emulated and their own instrument along with the remaining instruments of the recording. As the user becomes more proficient at the particular piece of music, hearing the instrument in the music (that is being emulated by his own performance of his own instrument) may then become a distraction or hindrance to the learning process. At this stage it may be preferable to hear only the user's own instrument and the accompanying instruments of the recording, while excluding the instrument in the music that the user is trying to emulate or to learn.

Various users may desire to learn different instruments played in a particular piece of music, and hence, there is a need for a custom mixed version of the music with each instrument being selectively removed or included at the user's choice. Another desirable feature users may want during the learning process is for the tempo of the recorded music to be changed to a slower rate without changing the pitch of the music. This feature may be especially desirable when the user is unfamiliar with the flow of the music. As the user becomes more proficient, it may then be desirable to increase the tempo of the recorded music, Similarly, changing the pitch of the music without changing the tempo is another desirable manipulation, thereby allowing the music to be transposed into another key, for example. Changing the pitch further allows the music to be tuned to the instrument being played rather than requiring a re-tuning of the instrument to match the pitch of the recorded music.

Another aspect of learning to play a particular piece of music or instrument is the desirability for the user's own instrument to match the textural effect or sonic characteristics of the instrument in the recording, as generated during the recording process. Matching textural effects is particularly difficult with instruments such as the electric guitar or bass wherein extensive processing of the musical signal is common. It may thus be desirable for the user to have, for each instrument within the music if applicable, predefined musical special effect setup information that can be load into a musical effect processing device to emulate the signal processing that is done to match the textural effect or sonic characteristics of the initial music recording.

In addition, it may also be desirable for the user to have and select a copy or graphic representation of the written musical score pertaining to a desired instrument for the piece of music. In short, a need exists for improved systems capable of delivering recorded music and providing users with increased control functionality.

Adjustable holding device for a musical instrument stand
2010-03-04
/>[0004] A conventional musical instrument stand substantially comprises an extension shaft and a main shaft, and the extension shaft is retractably inserted into the main shaft. The extension shaft can be pulled out from the main shaft to adjust the length of the stand and is held in place with a bolt to fit different needs of users.

[0005] Some musical instruments, such as cymbals need a stand with an inclined bar for holding the musical instruments to allow a user to conveniently strike the musical instruments. A conventional stand with an inclined bar is implemented with a holder having teeth, so the inclined bar can be held in place relative to the stand. However, the inclined bar cannot be folded relative to the stand, such that a large space is needed for storing or transporting the conventional stand with an inclined bar.

[0006] Therefore, the invention provides an adjustable holding device for a musical instrument stand to mitigate or obviate the aforementioned problems.

Electronic musical instrument with automatic and semi-automatic playing apparatus
2010-02-05
The storing of the received MIDI message into the buffer is executed in an interrupt process caused by reception of the MIDI signal. At steps S5 and S6, a semi-automatic playing and an automatic playing processes are performed, respectively, as described later in detail. At step S7, other necessary processes including an effect provision process are executed.

FIG. 3 is a flowchart showing a procedure of processing keyboard events at Step S3 in FIG. 2. At Step S10, it is examined whether key-on is issued or not. When yes, the procedure goes to Step S11 where the key-on counter for counting the number of keys in the key-on mode is increased by one. It is then examined at Step S12, based on the switching action in the panel circuit 5, whether the semi-automatic play mode is selected on or not. If not, the procedure moves to Step S14, while when yes, it advances to Step S13.

At Step S13, it is examined, based on the switching action in the panel circuit 5, whether rhythm play is turned off or not. In the semi-automatic play mode, the rhythm play can be turned on or off by switching action of a player. When the rhythm play is off, the process for the semi-automatic play is carried out. If the rhythm play is on, the same playing procedure as in the full-automatic play mode is performed as a sample play of a piece. The electronic musical instrument of the present embodiment is assumed having an on/off control of the rhythm play but is not limited as such. It may be selected between the semi-automatic play mode and the sample play mode by only switching on or off the semi-automatic play mode.

When it is judged negative at Step S13, the procedure goes to Step S14, while if it is affirmative, to Step S15. At Step S14, common operations for the full-automatic playing including the key-on or other known process for key assignment and a tone control are carried out.

At Step S15, velocity information for the semi-automatic play is saved in a given area of the RAM 4. The velocity information is entered as a touch data during the key depression by the player for the semi-automatic playing and used for envelope control. The key number is not needed for the semi-automatic playing, but may be saved for use entry of chords with the keys of the keyboard grouped into chord sets.

At Step S16, it is examined whether or not the simultaneous press timer is operating a time counting which disables all of succeeding key depressions when a single key or more than two different keys are erroneously depressed within a minute length of time considered as being simultaneous, i.e. determining whether or not the key depression in question is the first one in a predetermined limited minute time. In general, it is first judged not and the procedure moves to Step S17.

At Step S17, steps are followed for setting a data reading request corresponding to the key depression, starting the simultaneous press timer, clearing a sample play flag used for judging whether the automatic playing is recalled or not, and setting a sample play timer for detecting the timing for setting the sample play flag. Meanwhile, any of the succeeding key depressions implemented before time up of the simultaneous press timer is neglected.

At Step S18, it is examined whether or not the keyboard event is a key-off action. When yes, the procedure advances to Step S19 for subtracting one from the count of the key-on counter. It is examined at Step S20 whether the semi-automatic play mode is selected or not. If not, the procedure goes to Step S22, while when yes, to Step S21. At Step S21, it is determined whether the rhythm play is turned off or not. If not, the procedure moves to Step S22 for key-off process. When yes, the procedure is terminated. Each musical tone data in the play information includes a timing data for the key-on and a time (gate-off time) data up to the key-off. The duration from the key-on to the key-off is measured by a timer set with the gate-off time and upon the duration ended, the key-off is executed.

FIG. 4 is a flowchart showing a semi-automatic mode process at Step S4 in FIG. 2. At Step S30, it is determined whether the rhythm play is turned on or not. When yes, the procedure goes to Step S32 and if not, to Step S31. It is determined at Step S31, based on the sample play flag, whether the sample play is being performed or not. If not, the procedure moves to Step S37 and when yes, to Step S32. Steps S32, S33, S35, and S36 are transition steps to the full-automatic play, which are executed when it is judged that no key depression is made for a predetermined period of time during the semi-automatic playing.

At Step S32, it is determined whether the count of an automatic play request counter is zero or not. The automatic play request counter counts the elapsed time from the preceding automatic playing process and counts up whenever the predetermined period of time K has been elapsed as is triggered by the timer interrupt process which will be explained later. The predetermined time K is set to a length equal to "one step" in the full-automatic playing.
