Brad, It seems there are a number of ways to interpret whether an application which links to a GPL library must be open-sourced as well (based on wikipedia's expert legal advice). But it's great news to me that your interpretation is that RT CMix can be used in closed source applications. Should I

Take a closer look at Csound. This is a very confusing world, and you never know who to trust, but Csound is actually released today under the LGPL, that L meaning "lesser", and the general idea of this is that it's for software libraries more than end-user products, and it includes provisions for

Hmmm, my understanding of the GPL we adopted was that it only applied to the source of RTcmix, _not_ to the 'enclosing' app. The way we set up the iRTcmix apps, we have a 'manager' class (source provided) that calls into the RTcmix engine. Any mods you would make to the RTcmix source *proper* wo

Thanks Brad, Just bought ilooch. Lovely stuff. Unless I'm mistaken though, I'm required to make my source code publicly available if I embed RT CMix because it's licensed under the GPL. I swear, I'm not an _entirely_ evil person, but for a few reasons, I don't think it's going to be possible to op

Thanks Oliver. Just took a look. Looks like a very nice collection of functions, but as far as I can tell, it's quite similar to STK in that it will require me to manage connections between processors i.e. signal flow myself. -Morgan On Mon, Feb 7, 2011 at 7:54 PM, Oliver Larkin wrote: > Maybe th
