Ok, I've joined the club and fell off the fence last night. :)
I've got some presets but I'm not sure how to get them into LayR. Seems like you were supposed to be able to use iCloud for this, but my instructions from Brice only showing a method that involves using iTunes. Is there not an easy way to share/trade presets via iCloud or Dropbox?
Skip - on both "Load" screens (performances and instruments), there is a little iCloud icon. If you tap that, it will open your iCloud drive from which you can import. Similarly, on the "Save" screens.
These are really fabulous presents. Not only are they very useful for musical purposes but they are great tutorials in themselves. I love this synthesizer app. The arpeggiaroris amazing. Some of the arpeggiator sample presets that come with this app are fantastic too.
