Hi there,
As you don't seem to have an organised bug reporting system (?) I will try to submit a bug here.
It's probably more in the 'unwanted behaviour' category than a bug as such.
If the number of syphon sources changes - Madmapper loses it's connection.
This is a bummer if you wish to setup a new application to use as a Syphon input. It's just one click in Madmapper to solve it but still not nice in the middle of a gig.
For instance yesterday we had Modul8 running and then started up CoGe. When the new Syphon surce from CoGe came in Madmapper lost the Modul8 syphon input.
