    1. Hanzbirger – good question!

      The app is multiplatform – Windows, Mac & iOS – and the image we used was one that they used to illustrate the app on their site.

      We updated this to be a gallery of images for the iOS version, to avoid confusion.

      Thanks for the feedback!

  1. I bought this app and the IAP for advanced (pro) features. No regrets. It is a fantastically powerful app. There aren’t many apps that support any time signatures, changing time-signatures, and tempo maps.

    MTS is a DAW that does so much and has a very effective workflow. It is great with audio, great with MIDI editing, and has decent built-in sounds and effects for sketching.

    I check the forums about once a week and the developer does respond not only to posts on the forum but adds requested features fairly often.

    He added grab handles for MIDI graphic editing that work great.
