kandi X-RAY | coremidi Summary
This is a CoreMIDI library for Rust built on top of the low-level bindings coremidi-sys. CoreMIDI is a macOS framework that provides APIs for communicating with MIDI (Musical Instrument Digital Interface) devices, including hardware keyboards and synthesizers. This library preserves the fundamental concepts behind the CoreMIDI framework, while being Rust idiomatic. This means that if you already know CoreMIDI, you will find very easy to start using it. The documentation for the master branch can be found here:

QUESTION
I am trying to deploy my first web app on Heroku however I am getting a PyObjc error while pushing the code. I am doing this on a Mac Machine. This predictive application is developed using Flask. I do not know why this error is occurring as I do not have the PyObjc in my requirements.txt
...ANSWER
Answered 2022-Feb-04 at 21:42applaunchservices appears to be Apple-only:
Simple package for registering an app with apple Launch Services to handle UTI and URL. See Apple documentations for details.
I suspect you don't need that, either. Did you create your requirements.txt from a pip freeze? There's likely a bunch of stuff in there you don't need.
I suggest you review that file and remove anything you aren't directly depending on. pip will find transitive dependencies (dependencies your dependencies depend on) and install them automatically.
Prune that file, commit, and redeploy.
QUESTION
I'm trying to write simple loopback virtual MIDI port on macOS using CoreMIDI in C. First of all, it seems I can't understand all the CoreMIDI terminology. Look please at the following picture:
...ANSWER
Answered 2021-Jun-28 at 10:51OK, I finally figured out how to build loopback system with CoreMIDI.
- Source is an input device from an app point of view
- Destination is an output device from an app point of view
So we just need to create destination with callback in which we will notify sources (with MIDIReceived) about new MIDI data arrived. So we provide source reference as an argument for callback in MIDIDestinationCreate and use this source inside the callback.
QUESTION
There is a tuple of UInt8's in a struct MIDIPacket. Normal assignment is like this:
...ANSWER
Answered 2021-May-28 at 20:08There's no official API for doing this, but IIRC, tuples of homogeneous element types are guaranteed to have a contiguous memory layout. You take advantage of this by using UnsafeBufferPointer to read/write to the tuple.
Usually this requires you to manually hard-code the tuple's element count, but I wrote some helper functions that can do this for you. There's two variants, a mutable one, which lets you obtain an UnsafeBufferPointer, which you can read (e.g. to create an Array), and a mutable one, which gives you a UnsafeMutableBufferPointer, through which you can assign elements.
QUESTION
probably a bit of a noob question so bear with me.
What do I want to do? I have a c++ class called main.cpp and with that I want to add the external classes of RtMidi. I can just move the RtMidi classes into the same folder as my main.cpp and include them from there, but it feels a lot cleaner if I can keep them in a sepperate folder.
The RtMidi folder comes with its own Cmake file, and my assumption is that I can build that folder first to create a library that I then can link to. Is this correct? I'm new to c++ and not 100% sure if this is the way you want to add external classes.
When trying to build my project RtMidi is built, but I'm getting a warning that the main.cpp file can't find the include.
I'm building this on a mac with Visual Studio Code and clang as the compiler if that's any help
main.cpp
...ANSWER
Answered 2020-Nov-12 at 14:26I can tell that you are new to cmake which is fine. Everyone has to start somewhere.
Basically you aren't getting the proper include directories that your 'Music' needs. And honestly that's not your fault you linked against the 'RtMidi' if they wrote their cmake correctly your project should have compiled.
Here is roughly the code you need (assuming the include directory you are referring to is called inc)

I want to write a simple program that will print the notes input from the keyboard. I have something already shown below, but the program will finish and won't wait there for midi signal. Any ideas? Thanks
The main file:

Please check out the AudioKit v5 Cookbook in SwiftUI. It includes a MIDI monitor example that prints out all of the the MIDI notes, program changes, and continuous control numbers that your app receives:

Take care,

QUESTION
Hi I'm newbie to AudioKit
I tried to follow the playground to write a simple midi listener https://github.com/AudioKit/AudioKit/blob/v5-master/Playgrounds/Playback.playground/Pages/MIDI%20Input.xcplaygroundpage/Contents.swift
However, when I created the "class MIDIReceiver: MIDIListener," I was not able to leave its inside empty, xcode asked me to override the funcs. "Type 'MIDIReceiver' does not conform to protocol 'MIDIListener'"
The screenshot is here https://i.stack.imgur.com/kUtBs.jpg
Do I really need to override them? Or how do I fill in those parameters of the funcs?
Thank you

I think I got it...
Right now the methods are:
...ANSWER
Answered 2020-Oct-21 at 04:44Just click the red circle thing and press "Fix" and it will add all the protocol methods for you. Then you can put code into the ones you need. All the protocol methods are required because when made things optional (or created an extension to the protocol that did default actions), the result was if we updated the protocol and developers neglected to update, they would lose their midi functionality. Now, if we change stuff, you have to keep up to date.
