چکیده

We describe a new approach for testing MIDI performance characteristics, which is both inexpensive and highly accurate. Following a description of the test method, actual results for a number of MIDI interface technologies are presented. These results show that jitter and latency performance of newer (USB-based) interfaces is actually two to three times worse than older MIDI interface technologies. Other potential applications of this technique are briefly discussed. Finally, we consider implications for the future, since the recent PC2001 Guidelines and WHQL (Windows Hardware Quality Labs) logo requirements will forbid the use of the older MIDI interface technologies in new personal computer designs

An In-Depth Analysis of Real-Time MIDI Performance

Although MIDI is often used for computer-based interactive music applications, its real-time performance is difficult to generally quantify because of its dependence on the characteristics of the given application and the system on which it is running. We extend existing proposals for MIDI performance benchmarking so that they are useful in more realistic interactive scenarios, including those ...

A Survey of Real-Time MIDI Performance

Although MIDI is often used for computer-based interactive music applications, its real-time performance is rarely quantified, despite concerns about whether it is capable of adequate performance in realistic settings. We extend existing proposals for MIDI performance benchmarking so they are useful in realistic interactive scenarios, including those with heavy MIDI traffic and CPU load. We hav...

On the Computer Recognition of Solo Piano Music

We present work towards a computer system for the automatic transcription of piano performances. The system takes audio files containing polyphonic piano music as input, and produces MIDI output, representing the pitch, timing and volume of the musical notes. The aim of this work is not to reduce the performance data to common music notation, but to extract the performance parameters for a quan...

Extracting Expressive Performance Information from Recorded Music

A computer system is described which performs polyphonic transcription of known solo piano music by using high-level musical information to guide a signal-processing system. This process, which we term expressive performance extraction, maps a digital audio representation of a musical performance to a MIDI representation of the same performance using the score of the music as a guide. Analysis ...
