Hi Marc,

first of all - great job done!!! The app is a miracle! We tested with six singers over two full-day rehearsals and they loved it! Had also two iPads connected and a laptop with Ableton Live, sending commands to the SD9. Nice thing is that we have OTH OSC commands punched in the ABL session and they worked along the iPad command-set, as we have both loaded in the console. So the console seems to accept multiple command-sets at a time.

The admin section is pretty intuitive, although a few minor touches would be nice:

• a hint to add a DiGiCo iPad external device to the console, not OTH OSC ... that took me like 30mins to realize :-D
• be a little more specific about receive and send ports, eg. "console's send"; these binary things always give me a headache
• add channel numbers to the channel section

We've also had a few issues, my notes from the rehearsal:

Error connecting new web client

Note:

1. Config of the digico session has changed during runtime - channels added.
2. Order of channels in the admin section was changed before adding new channels to console.

Webapp gets disconnected, but does not notify the user

• Probably only when app saved as a desktop app, it seemed to work correctly in a common browser - Safari, Chrome
• Tested on iPhone and Android

And finally a handful of "nice-to-have" feature suggestions:

• logarithmic scale on app faders, now they seem to be linear
• name of current snapshot in client app header
  • I have added that as a plugin, but changes to mixer.js obviously needed to be done too
  • After receiving “/Snapshots/Current_Snapshot” save snapshot number to a global var and send “/Snapshots/names/?” to receive the whole list; pick the correct number, get args[3] (snap name) and send an arbitrary msg to the clients to update the .innerHTML
• (Low priority) add an aux output level meter to the client app

Thanks a lot for all the great work, we will definitely send a contribution!
