How do I build it for I64?

[nonchai]

I ran and installed everything on my Intel Mac - only to discover it was for ( or defaulted to ) ARM64 not Intel Macs

how do I get it running on my Intel mac? ( Sonoma 14.5 )

Sorry for the delay in replying. Unfortunately I don't have an x64 Mac.
However there is no default for ARM64 - it is supposed to build both.
If you edit the package.json the line with "arm64" does it build correctly?

Yes, it seems despite being an array it can only accept a single string, so "arm64", "x64" doesn't work. Instead, "universal" is needed.

The full set of architecture options is:

"arm64" | "armv7l" | "ia32" | "universal" | "x64"

I made a PR after confirming the build still works for arm64 macOS when using universal:

#15

Unfortunately the build still doesn't work on Intel macOS, although it gets further. I'll share what I've observed below.

Here's what I see when running after building using x64 only (which I don't think is the right way forward):

(The ProtoZOA is detected but the main window is not populated as it is on arm64 macOS:

When building using universal, I see this popup dialog window when starting the app:

The app GUI never loads in this case.

[starfishmod]

That is an issue with the node midi library.
I might investigate if other forks of the node-midi library have improved on this issue.

@nonchai @kcoul

I managed to run it on Intel Mac. x86_64 architecture. Sequoia 15.2. The error is due to having MIDI library compiled for Apple Silicon.

rm -rf node_modules/midi

yarn add midi

yarn start

@unobatbayar if you end up finding this as a solution I'll add it to the docs as a solution
thanks for doing this work!
