in addition to their own software, many manufacturers do provide very

detailed loudspeaker data for external tools such as EASE, so it's not

that the data is not available. but it's a hefty piece of engineering to

write such a tool (at least if you want to simulate room reflections as

well, which most of the vendor-supplied tools happily ignore).
your best bet is a virtual windows machine and the software that comes

with the system for free.

same here. the data is usually available (unless the vendor also sells

controllers and wants to tie you to their own offerings).

but i don't see why anybody would be stingy with the controller (at a

measly 4k euros) when they've just spent well upwards of 50k for the

speakers...

in those price ranges, there is simply _no_ incentive to go open-source.

i agree it would be more fun, but it's not going to happen.
moreover, with an XTA, i know it only crashes when there's a machine

connected via USB (don't do that, then). with a pc to control the

speakers, i never know what it'll do next after being kicked about by

underpaid roadies who have no idea what's in the case they just tossed

out of the trailer.
