The Ghost has been developed to create a merger between the standard MIDI keyboard controller, MIDI/digital guitars and alternative desktop controllers. Using a custom software editor, The Ghost’s controls can be mapped to suit the users performative needs. The interface takes its interaction and gestural cues from the guitar but it is not a MIDI guitar. The Ghost’s hardware, firmware and softw...

This memo offers non-normative implementation guidance for the Realtime Protocol (RTP) MIDI (Musical Instrument Digital Interface) payload format. The memo presents its advice in the context of a network musical performance application. In this application two musicians, located in different physical locations, interact over a network to perform as they would if located in the same room. Underl...

A MIDI-to-OSC converter is implemented on a commercially available embedded linux system, tighly integrated with a microcontroller. A layered method is developed which permits the conversion of serial data such as MIDI to OSC formatted network packets with an overall system latency below 5 milliseconds for common MIDI messages. The Gumstix embedded computer provide an interesting and modular pl...

This paper will describe the design and implementation of PadMaster, a real-time improvisation environment running under the NextStep operating system. The system currently uses the Mathews/Boie Radio Drum as a three dimensional controller for interaction with the performer. PadMaster splits the surface of the drum into virtual programmable pads which can be grouped into scenes so that the beha...

Many modern polyphonic music transcription algorithms are presented in a statistical pattern recognition framework. But without a large corpus of real-world music transcribed at the note level, these algorithms are unable to take advantage of supervised learning methods and also have difficulty reporting a quantitative metric of their performance, such as a Note Error Rate. We attempt to remedy...

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 ...

This paper introduces Medusa, a distributed sound environment that allows several machines connected in a local area network to share multiple streams of audio and MIDI, and to replace hardware mixers and also specialized multi-channel audio cables by network communication. Medusa has no centralized servers: any computer in the local environment may act as a server of audio/MIDI streams, and as...

This memo describes a Real-time Transport Protocol (RTP) payload format for the MIDI (Musical Instrument Digital Interface) command language. The format encodes all commands that may legally appear on a MIDI 1.0 DIN cable. The format is suitable for interactive applications (such as network musical performance) and contentdelivery applications (such as file streaming). The format may be used ov...

Although the isolate was highly resistant to clarithromycin in vitro, the patient improved clinically as symptoms disappeared. Results of stool cultures taken 5 weeks after resolution of clinical symptoms were negative. The clinical course of thi...
