Lovely tool that offers a lot

This type of tool should’ve been standard for all music applications that come out today on iOS. Especially the DAWs. This app is very well implemented as a standalone and Auv3. The settings page for Auv3 could use an improvement to show more info on-screen.

Someone left a recent review that stating this tool didn’t work in Cubasis. Maybe it didn’t once but, it works well now! Now if Cubasis would give me the option to make KB1 the default keyboard, things would be golden!

Reward yourself with the future touch keyboards for iOS.

Preset saving is a total mess

When you load up an AUM project with kb1 in it, regardless of the actual state of the app when you saved, it loads up in the standard keyboard layout. But even worse than this, apparently you can’t have different note mappings between presets. What I mean is, if you have pads set to play a series of notes and save it as a preset, and then make a new presetwith different notes, it also changes the notes in the original preset. I don’t understand how this is so highly rated with these issues. I emailed the devs about an issue with Octachron a week ago and have t heard back, so apparently they’re not too keen on actually fixing bugs. So, buyer beware.

EDit: also, velocity doesn’t work with rolls on the drum pads.
