I downloaded the files from the Build a MIDI Synthesizer tutorial for JUCE and edited the coding in it according to what the tutorial said. After I saved it and opened it in my IDE, I tried to compile and run it, but several errors popped up instead, and I don’t know how to fix or get rid of them, or whether I should fix the code in JUCE or in my IDE application. These are some of the errors that I am seeing in my IDE. (I’m using Xcode.)
I wasn’t able to attach all of the errors into one screenshot, so I’m sharing some of them for now.
