A Code Example/Tutorial on Dragging Audio and MIDI to the DAW [UPDATED WITH VIDEO]

[clevername27]

EDIT: All works now, thanks to the tireless efforts of @Christoph-Hart. Thanks, man!

This code example demonstrates how to:

• Load a MIDI file.
• Draw a map of the MIDI file in a Panel to check if it loaded properly.
• Play back the loaded MIDI sequence, synched to the DAW.
• Create a panel allowing the MIDI file to be dragged to a DAW.
• Render the MIDI file to audio (with the currently-loaded Sample Map).
• Create a panel for dragging the file to a DAW.

The code is straight from my plugin. I've commented it to explain what's happening at each line. Comments/feedback/corrections encouraged/appreciated. [EDIT: @Christoph-Hart improved my code, and added it to the Snippets library — use that code.]

EDIT: Here's the usage case, including a simple progress bar:

Cheers to you man, snippet?

@clevername27 God Bless man, Amazing Work :victory_hand_light_skin_tone:

[Christoph Hart]

Why is that

Most likely a file permission issue - I see you're writing it to a location inside the app data directory, this might cause some issues.

But it's a nice example of a heavily underdocument feature so I'm refactoring it a bit and will add this to the HISE snippet browser.

[clevername27]

@Christoph-Hart Thank you for the kind words. I thought so, as well about the permission – I tried the Documents and Downloads folder – on both cases, the OS asked permission and I granted it. Same result, tho. I'll try some other permutations. I've also amended my original post to see if someone can try this under Windows or GNU/Linux, where I suspect it might work fine.

@Christoph-Hart said in A Code Example/Tutorial on Dragging Audio and MIDI to the DAW*:

I'm refactoring it a bit and will add this to the HISE snippet browser

I just saw the snippet browser link in the help menu. Clicking on it crashes HISE here.

[Christoph Hart]

@d-healey can you check if it only happens on Linux?

There‘s a lot going on there, it creates another HISE instance in a new window that you can use next to your currently loaded project but it might be a bit funky on Linux as I haven‘t tested this yet.

[ulrik]

@Christoph-Hart it works on Mac

[d.healey]

Works on Windows here.

It works on Linux in a debug build but not a release build. And it takes ages to open the snippet browser.

I'm wondering, does the snippet browser thing respect the USE_LINUX_FONT_HANDLER flag? I remember if I have this enabled then it takes ages to open HISE so I always disable this in my release build but I have to enable it in the debug build otherwise it won't open.

[Christoph Hart]

@d-healey Does it take longer than the initial startup of HISE?

[d.healey]

@Christoph-Hart The debug build of HISE takes about 6 seconds to open, from within there the snippet browser takes about 12 seconds. So roughly twice as long.

[clevername27]

@Christoph-Hart Thanks for the suggestion - I notice that the MIDI file was getting written OK (to the App Data folder), so I tried the same with audio - same thing. I know you're busy - if you have a chance, do you have any further thoughts? Thank you.
