Found an Internet Archive snapshot of the page at
http://hise.audio/manual/ios.php
which currently displays some error. There I found helpful information on the missing pieces:

• wasn't using the Xcode project generated at Binaries/Builds/iOS/
• needed to add the Apple Team Development ID in the HISE User Settings and an App Group ID in the Project Settings

Now the same basic project, which I've previously built as a desktop standalone and -plugin application, runs on an iOS simulator and an iPhone device, which is quite amazing.

Hi - I'm interested in catching the iOS train and might have enough tolerance for frustration. The experience @ursbollhalder describes above seems to give some hope. I wouldn't be doing complex interfaces, to begin with at least, so suboptimal graphics performance might not be a problem.

But I'm unsure how to start experimenting in space: With my HISE project open in Xcode, I only see a Mac run destination; no iPad/iPhone simulator or device destinations (even though a device is connected and shows up for other Xcode projects).

If I open Binaries/AutogeneratedProject.jucer in Projucer, from within my HISE project, I only see an option for a Xcode (macOS) exporter, while with HISE Standalone.jucer open in Projucer, for compiling HISE itself, I see an Xcode (iOS) exporter option.

Do you have any ideas on how to overcome this initial hurdle?

@d-healey The aim is not to have the sample maps predefined, but generated mechanically.

For a bit of a context: I'm exploring those possibilities for the synth.is project, where you can evolve sounds[1], render them as sample packs and currently download them along with programmatically generated SFZs[2]. Many things broken there and I aim to continue working on this research project in the coming years, but all are very much welcome to play with this (I know the interactive evolution part is broken, which is a regression resulting from work on quality diversity search for sounds - I welcome requests for accelerated fixes : )

Just as SFZs can currently be rendered and downloaded, it would be nice to be able to obtain those sounds directly in a plugin.

(YouTube links here as inlining above was causing problems)

@d-healey Great! I'll look into those as well.
