Renoise As Rewire Slave - Could It Be "Called" By Rewire Maste

Hi… I’m under the misimpression that Live can, for instance, call Reason from within an .als song that somehow magically spawns up a Reason when the .als is loaded.

Could Renoise be as clever? :)

for as far as i know, Renoise should be loaded automatically when it has been saved to act as a ReWire slave. It however doesn’t automatically load the song that you were working on when you slaved Renoise in the previous session to your host.

How is it saved to act as a ReWire slave, please?
