16: MIDI part 2, C++ Real-Time Audio Programming with Bela

Lecture 16 of C++ Real-Time Audio Programming with Bela. This lecture is the second of a two-part series introducing the MIDI protocol. (First lecture: • 15: MIDI part 1, C++ R... )
In this lecture:
Section 1: MIDI on Bela 0:00
Section 2: Pitch wheel 7:05
Section 3: Control changes 17:06
Section 4: Mod wheel and LFOs 25:26
Section 5: Portamento 34:01
Example code and companion materials:

This course is a deep dive into how Bela processes data, and how to implement real-time audio and interaction. If you want to learn or improve your skills with C++ and audio programming, this is a great way to start!
Bela is the open-source platform for creating beautiful interaction. If you’d like to get a Bela system to follow along with these lectures, visit shop.bela.io. Use promo code CREATEATHOME for £10 off Bela and Bela Mini Starter Kits.

I'm not quite sure what this is or how I got here, but this stuff looks really cool!

Excellent, as always. I've worked through all of these over the last couple of weeks, and found the pace, presentation, and depth to be spot on. I hope you keep them coming! Would love to see something on granular synthesis. Minor style comment - suggest you use e.g. _Sec, _Hz, etc variable suffices to indicate what the unit is. This avoids potential confusion about whether the value is e.g. a midi value, an analog I/O value, a voltage, time in samples, time in seconds, frequency in Hz, fractional frequency, etc. I've added them to my own code and find it makes things clearer. Anyway, fantastic series, long may it continue!

Thanks for the feedback! Good suggestion about variable naming conventions. That is indeed a helpful way to remember what the values mean, certainly worth considering if used consistently.
