Issues arise when:Attempting to load Soundfonts for custom music production. This manifests as, often, no sound being played despite the Soundfonts being chosen and their operability. Returning to a project, in the form of a giant X appearing instead of any form of initialization. Areas for improvement can be seen when: Wanting to record or import sounds from external sources falling outside of MIDI. This could circumvent a reliance on Soundfonts, when fixed.These three things would place Helio far ahead of several options available on the App Store.

On the iPad version, there is no way to save a .helio file, despite the fact that it creates a 0kb .helio file on song creation. While customizing instruments in the orchestra pit, a lot of times when I try to add some effects, the app immediately crashes. On the page where you create projects, it has a list of projects recently worked on, but when you click on those projects, it disappears from the list, and adds an empty item to the studio menu and deletes the project with no undo.

It’s great, really good. But whenever I load a relatively small-ish sound-font (sf2, 149mb) it crashes for some reason, but this is the only HQ sound-font I could find below 200mb, pls fix it

Developer Response
Thanks for reporting, could you send me a link to this soundfont? I've never stumbled upon sf2 files that would crash the app. Please feel free to contact via email (peter.rudenko@gmail.com) or github (https://github.com/helio-fm/helio-sequencer/issues)

- New refactoring command: join adjacent notes - New option: show MIDI numbers next to note names - Keys on the timeline can be selected and dragged or transposed in groups - Long tap on a note or a clip switches the drawing mode and the cutting mode to the opposite - You can render part of the project to audio by setting the reprise signs - Added a toy scripting language for algorithmic music (beta) - Reworked the old blueish color scheme - Added options to scale the UI x0.5 and x0.75 - A few UI speedups
