Hi all! I'm the developer of RailControl Pro, and happy to answer all your questions, discuss features and ideas here.
In a nutshell: RailControl Pro is an app which runs on iPhone, iPad and Mac. I'm trying to give a better user experience for Märklin Central Station 3 with this app, especially on mobile devices. There's still a lot to be done, and since I'm building this app alone in my spare time, unfortunately features grow pretty slow. I'd love to dedicate professional time on it too, but for that the sales are not strong enough yet 😜
EDIT: RailControl Pro now also lets you connect to Central Station 2. See post below.I think the basis is solid though:
- Controlling locs:
- Precise speed control through +/- buttons or with an old fashioned slider
- Natural acceleration/braking through predefined settings
- Multiple in parallel on iPad and Mac
- Works with keyboard shortcuts on iPad and Mac
- Through a game controller like the one from PlayStation or Xbox
- Controlling accessories through a keyboard like interface, or through the track diagram
- CS3 Start/Stop
- Shutting down/Rebooting CS3
Things I'm working on right now:
- A better speed slider (edit: done)
- Editing locs (stuck on an issue with writing to mfx decoders)
- Assigning a loc to a specific game controller, so one iPhone can control 1 loc, and all connected game controllers can control other locs (edit: done)
Things I want to add in the near future:
- Editing articles
- CS2 Track Diagrams (edit: done)
- Executing Events (edit: done)
The idea is that once all this core functionality is done, I focus more on deep platform integration: e.g. controlling locs from Apple Watch, integrate with Siri/Shortcuts (e.g. "Siri, start loc 186-902").
I don't want to create a new RocRail, but rather the app Märklin should have included with CS3. It should be easy to use, and self explanatory for new CS3 users.
All feedback, suggestions and questions welcome!
