Along with the recent release of McLaren Labs rtpmidiversion 0.5.0, we have new ports to Raspberry Pi 4 Raspbian OS “Buster” and also Ubuntu 19.10 “Eoan Ermine”.
We are especially excited to release the port to Raspbian “Buster!” The Raspberry Pi 4 has more computing power and higher bandwidth connectivity. This makes the Raspberry Pi 4 even more exciting for music and media creation. And now, with McLaren Labs rtpmidi you can send MIDI messages over Ethernet and WiFi to a Raspberry Pi 4.
This month McLaren Labs releases rtpmidi version 0.5.0 for Ubuntu and Raspberry Pi. This release brings some great new features, and also provides a few performance and installation improvements.
More MIDI message types … including SysEx
McLaren Labs rtpmidi has always supported the following message types with full Journal capability for sending and receiving. (Note: The Journal is part of the error correction mechanism that recovers lost messages that occur when sent over a network.)
Note On, Note Off
With this release, we also add the following to provide a complete set of MIDI message types including System Exclusive.
McLaren Labs was started with the idea that music and media creation on Linux should be as easy and fluid as Mac OSX. We had been inspired by AVFoundation and the modular way its pieces fit together. We loved being able to build media pipelines with sources and sinks that cleaned up after themselves when you were done with them them.
Many of the facets of the OSX components we liked were provided by ObjC features enabled by the Clang compiler and LLVM tool suite. LLVM has revolutionized language development by paving the way for Swift and Rust. Back at the time we were getting started, Swift on Linux was gaining traction and we considered adopting it. However, after some initial explorations with Swift and libdispatch, we discovered that libdispatch just wasn’t ready with Swift on Linux. That was in 2015 – Swift on Linux is much more mature. The equation might be different today … but it might not too.
Remote musical MIDI collaboration has been an interesting academic research area for years, but has not been explored by many casual musicians. One reason is that the complexity of software that brings MIDI and Networking together makes it a little bit of a daunting endeavor. We think it’s time to open exploration to more people and make remote MIDI collaboration as easy as joining a Hangout.
What is Network MIDI?
Back in 2001, a group of researchers at Berkeley began to experiment with remote musical collaboration . The idea was see if musicians separated by some distance could collaborate in real time over a high-speed network. Rather than sending real-time audio signals, MIDI events were transmitted between instruments at two different locations.
You may have heard a new term recently: “The Tactile Internet” . The Tactile Internet is the next evolution in the Internet of Things, where humans and machines can interact in real time, and with a very low latency. Low latency capabilities will enable new applications. The Tactile Internet will allow people to interact with remote environments and in real-time.
The enabling technology is 5G. The 5G standard defines a new class of service called “Ultra-Reliable Low Latency Communication” (URLLC). URLLC not only increases uplink speed, but also eliminates some of the handshakes necessary for an endpoint to send some data up to the network . The end result is that applications can inject data into the network at a much reduced latency. Continue reading “Towards the Tactile Internet of Musical Things”
