Sometimes has more serious consequences that a pop or click. And unlike audio information, lost MIDI data Things out, there’s always a chance to throw out the wrong item. The Event Processor uses built-in algorithms to try to thin the data in these cases, but anytime we throw Even if theĮvent Processor can keep up with the task of duplicating the notes, they’re being stockpiled faster than MIDI If you’re playing 64th notes on Channelġ, and the Event Processor is copying each note to Channel 2-16, well, something’s got to give. Processor can’t be offloaded any faster than 3,125 bytes per second. ‘drainage’ issues under severe cases, the real culprit is usually MIDI itself. Although the Event Processor itself can have The ability to fill it, or ‘sink’ is going to overflow. The ability to empty the ‘pipe’ has to match Pouring buckets of water into a sink with a little drain pipe. The Event Processor is programmed to map several output commands for each one it receives, it’s kind of like The one thing that can bring the Event Processor to its MIDI ‘knees,’ sooner or later, is data duplication. Handle this better than others it’s just something to be aware of. Dropping Note On messages isn’t so bad, especially when there areĭozens of them happening at the same time, but missing Note Off messages are big trouble. However, the MIDI keyboard may also enter the picture by dropping note information if it The Event Processor itself is immune to failure due to fully loaded MIDI bandwidth it’s happy to send 31,250īits per second.

Keep this in mind when you consider sending a merge of 4-5 MIDI outputs to one cable, and "let Can an average PC/Mac sequencer and an 8x8 MIDI interface up the ante? Youīetcha. Can Joey DeFrancesco or Chester Thompson play faster than one note per millisecond for Struck and released in a very short time, even though the average notes per second throughout the song might Hammond Organ techniques like "smears" and "palm glisses" -– require that a lot of notes be Like an awful lot of time to send MIDI, but the figure can be deceiving. MIDI runs at 31.25Kbit/sec., which works out to roughly 1,000 average MIDI commands per second. Here’s a brief guide to understand the rules that the Event Processor can’t break. Used outside the rules, though, it can sometimes make things very unpredictable. Had more horsepower than you ever dreamed possible? It was much easier to get from Point A to Point B it wasĪlso much easier to end up in a ditch! Used within its designed intentions, the Event Processor can’t help but Did you ever get behind the wheel of a really powerful car or motorbike –- one that As an example consider this device: which offers 192 keys and currently has to work around the limitations of midi by using 2 midi channels to use all the keys.OK, by now you’ve probably figured out that there’s nothing MIDI that the Event Processor can’t deal with, Note that direct pitch control per note does not really feel like a proper solution, as it will result in a single midi note number being used for addressing several frequencies, which (as far as I understand) makes it impossible to play 2 or more of those frequencies simultaneously.Įdited to add: this is not a "theoretical problem" anymore.

The topic of more than 128 note numbers comes up in microtonal/xenharmonic contexts much faster than in traditional music. With so many other specs becoming better this seems like some kind of oversight. Looking at the midi 2.0 note on/note off messages, do I understand correctly that it still supports only 128 distinct note numbers? Technically one could abuse the 'attribute' to add extra numbers but that would be a manufacturer-specific extension, so not much hope for cross-device compatibility (and if you use the attribute for note number, where do you then specify the tuning information?).
