TheSteven Posted February 24, 2019 Share Posted February 24, 2019 (edited) MIDI Association Feb 23rd news on MIDI 2.0 MIDI 2.0 prototyping session at Winter NAMM 2019 At the MIDI 2.0 prototyping session at NAMM, a number of MIDI 2.0 features were demonstrated. There have been over 100,000 people who have visited the MIDI.org site in the past month viewing the information on MIDI 2.0. We have been monitoring the comments on various websites and wanted to provide some more information about MIDI 2.0. to clarify several points. ----------------------------------------------------------------------------------------Will MIDI 2.0 devices need to use a new connector or cable? No, MIDI 2.0 is a transport agnostic protocol. -Transport- To transfer or convey from one place to another -Agnostic- designed to be compatible with different devices -Protocol-a set of conventions governing the treatment and especially the formatting of data in an electronic communications system That's engineering speak for MIDI 2.0 is a set of messages and those messages are not tied to any particular cable or connector. When MIDI first started it could only run over the classic 5 Pin DIN cable and the definition of that connector and how it was built was described in the MIDI 1.0 spec. However soon the MIDI Manufacturers Association and Association of Music Electronic Industries defined how to run MIDI over many different cables and connectors. So for many years, MIDI 1.0 has been a transport agnostic protocol. MIDI 1.0 messages currently run over 5 PIN Din, serial ports, Tip Ring Sleeve 1/8" cables, Firewire and Ethernet and all the different variations of USB cables. ---------------------------------------------------------------------------------------------------------------------Can MIDI 2.0 run over those different MIDI 1.0 transports now? No, new specifications need to be written for each transport. There is a new Universal Packet Format that will be common to all modern transports that will help make this work move quicker. The new Universal Packet contains both MIDI 1 .0 messages and MIDI 2.0 messages plus some messages that can be used with both. The most popular MIDI transport today is USB. The vast majority of MIDI products are connected to computers or hosts via USB. USB is the first target for MIDI 2.0. ----------------------------------------------------------------------------------------Will MIDI 2.0 provide more reliable timing? Yes, and not only that the timing for MIDI 1.0 can also be improved. One of the new messages that can work with both MIDI 1.0 and MIDI 2.0 are Jitter Timestamps. Goals of JR Timestamps: -Capture a performance with accurate timing -Transmit MIDI message with accurate timing over a system that is subject to jitter -Does not depend on system-wide synchronization, master clock, or explicit clock synchronization between Sender and Receiver. Note: There are two different sources of error for timing: Jitter (precision) and Latency (sync). The Jitter Reduction Timestamp mechanism only addresses the errors introduced by jitter. The problem of synchronization or time alignment across multiple devices in a system requires a measurement of latency. This is a complex problem and is not addressed by the JR Timestamping mechanism. ----------------------------------------------------------------------------------------Can MIDI 2.0 provide more resolution? Yes, MIDI 1.0 messages are usually 7 bit (14 bit is possible by not widely implemented because there are only 128 CC messages). In MIDI 2.0 velocity is 16 bit and the 128 control change messages, 16,384 Registered Controllers, 16,384 Assignable Controllers, Poly and channel pressure and Pitch Bend are 32 bit. ----------------------------------------------------------------------------------------Can MIDI 2.0 make it easier to have microtonal control and different non-western scales? Yes, MIDI 2.0 allows direct pitch control of individual notes ( see video) More MIDI 2.0 info... Edited February 24, 2019 by TheSteven 2 Link to comment Share on other sites More sharing options...
JohnG Posted February 24, 2019 Share Posted February 24, 2019 (edited) Well, that's good then. What the article fails to ask and answer, and perhaps should, is Q: "Will my current MIDI 1.0 devices all still work okay?" A: "Yep!" Q: "If I connect a MIDI 1.0 device to another device or computer running MIDI 2.0 will it still work?" A: "Yep! But only in MIDI 1.0 mode, none of the new MIDI 2.0 features will work with your MIDI 1.0 device." Q: "Aha! So MIDI 1.0 works unchanged to MIDI 1.0 and MIDI 2.0, to get the new features both ends must implement MIDI 2.0?" A: "You've got it!" Q: "Will my insert manufacturer and keyboard/EWI/guitar/etc. be upgraded to MIDI 2.0?" A: "Don't be so bl**dy lazy you ignorant fool, ask the blinkin' manufacturer! How the hell should I know?"" End.

JohnG Posted February 24, 2019 Share Posted February 24, 2019 (edited) And ... Q: "And will the new interface provide parallel working so that all the notes in a chord can be sent simultaneously?" A: "What "new interface" and "no" ... Dumkopf!" Edited February 24, 2019 by JohnG 3 Link to comment Share on other sites More sharing options...
craigb Posted February 24, 2019 Share Posted February 24, 2019 Q: "Will it work if I use cables that aren't black or white?" A: "Please do not procreate!" 1 Link to comment Share on other sites More sharing options...

abacab Posted February 24, 2019 Share Posted February 24, 2019 If you only use white cables, everything you play will be in Am. Link to comment Share on other sites More sharing options...
InstrEd Posted February 24, 2019 Share Posted February 24, 2019 The black cables will be in??? Link to comment Share on other sites More sharing options...
willard cottrell Posted February 24, 2019 Share Posted February 24, 2019 These latter posts remind me of the original Startrek where there are two "warring" factions. One had black on the left side and the other on the right side. Kirk was astonished about the conundrum! Link to comment Share on other sites More sharing options...

InstrEd Posted February 25, 2019 Share Posted February 25, 2019 Hmm, would that be Gull Gray considering it is the U.S.S. Enterprise ? Link to comment Share on other sites More sharing options...
InstrEd Posted February 25, 2019 Share Posted February 25, 2019 I stand corrected by myself. Maybe it should be Aircraft Gray not Gull Gray Link to comment Share on other sites More sharing options...

Øyvind Skald Posted February 25, 2019 Share Posted February 25, 2019 (edited) This sounds really great. I hope Native Instruments use this as fast as possible. I really want the microtonal stuff. As Baroque music is supposed to be tuned at around 420Hz and they didn’t use equal temper. They had many different tempers. Another please is bass and guitar programming. They are also not equal tempered, and it would be great to fix it so it sounds as a bass and not this “perfect pitch” sample. I don’t think you will need to resample anything. You might just put in a pitch filter. Edited February 25, 2019 by ØSkald 1 Link to comment Share on other sites More sharing options...
JohnG Posted February 28, 2019 Share Posted February 28, 2019 (edited) What you need is one of these: https://cdn1.imggmi.com/uploads/2019/2/28/82ad5488a9531a5c267b6782867b5b50-full.jpg Then you won't have to rely on any much vaunted MIDI 2.0. It works from Scala (.scl) files. Edited February 28, 2019 by JohnG Link to comment Share on other sites More sharing options...

JohnG Posted February 28, 2019 Share Posted February 28, 2019 (edited) That was the original problem, it was too small to be read when I did a direct upload. Let me try again. Nope, it keeps reducing the image size. "If, at first, you don't succeed, try, try, try again." Then give up, it's no use bangin' your head against a brick wall.
