JAX MIDI ModulePlayer app for iPhone and iPad

There is a manual at: https://midi.digitster.com/JAX%20MIDI/JAX%20MIDI%20ModulePlayer.pdf
And a demonstration video at: https://youtu.be/DKwRxcfgy8s

JAX MIDI Module & Player can be used as a GM/GS (General MIDI) compatible multi-timbre synthesizer for playing live or as a file player. It is usable as a sound module for external MIDI signals and as audio unit for usage in any host application, which supports Apples AUv3 format.

With JAX MIDI Module & Player you can load available standard MIDI files and just play them back. It has inbuilt a fully featured GM/GS synthesizer with over 370 different instruments and drum sets, which is also playable in realtime on 16 MIDI channels simultaneously.

The module works like the classic external hardware modules of the late 90s. If used as an audio unit, the MIDI stream is passed thru, so that other apps (like synthesizers and drum machines) can profit from the file playback. Internal sound generation can muted with the main volume slider.

Important GM MIDI controllers are supported and also displayed for overview. The playing state of all channels is displayed in realtime.

For JAX MIDI Module & Player, you may create your own MIDI files with notes with any external MIDI editor that can create standard MIDI files format 0 or 1, with controllers and tempo changes and all and then play back thru it with the internal or any external instrumentation.

AudioUnits (AUv3) require a supporting host application to perform. But our app is able to perform as a standalone host for the embedded unit and provide basic Core MIDI functionality for communicating outside the sandbox.

This build is truly universal, meaning, the unit is available for:

- MacOS (Silicon M1)
- iOS (iPhone)
- iPadOS (iPads)

Note: We now will separate the native macOS release (Mac Catalyst) from the iOS universal release, because native macOS releases need special optimizations. There also will be different prices for the native macOS apps.

Making AUv3 technology available across all devices (for usage with GarageBand, Logic Pro X, MainStage 3 on the Mac), is quite a challenge.
And we have chosen to deliver the releases across all devices instead of asking multiple times for money.

Our builds come with latest technology support for all Apple devices (at the point of release). We therefore always develop with latest Apple frameworks and compilers. But we try to keep the compatibility at minimum requirements as far as even possible. Especially the latest M1/2/3 and cross platform optimizations forced us to drop all the legacy device support (below iOS 14). This is also true for all our older apps, which will be updated step by step to reflect the latest technologies.
