Let's shed some light on the StitchBuddy piece - as there are some topics addresses and questions asked:
- There are two StitchBuddy versions for Mac and iPhone/iPad with very similar (but not identical) features; a design can be rotated with both apps
- Both versions are offered as free trials in Apple's App Store, only restricted when saving modifications = limited to designs with max. 1,000 stitches. This limitation can be removed within the apps ("In-App purchase") for USD 9.99 resp. USD 49.99
- JPX files can be read, but not written by StitchBuddy; not a serious limitation as JPX files are just including additional background images (which will be ignored when importing), and all Janome machines accept JEF files - Jim, please step in to add anything significant :)
- To rotate a design (or a part of it) relevant stitches need to be selected, first (e.g. with the menu command "select all"); then rotations by 45 degrees or individual ones are available in the "Design" menu on macOS or "Tools" menu (little wrench) on iOS; there is a dedicated "hoop" menu with numerous Janome hoops to select from
- To transfer a design directly from your iPad to a USB stick, Apple's "Files" app becomes handy: You can copy files from StitchBuddy's repository directly to the stick; depending on your iPad and the stick this might require a Lightning-USB (female) adapter aka "Lightning Camera Adapter"). Here is a video tutorial showing the transfer process: iOS 13 Integration
