I just noticed while reading through some LOR stuff on the LOR site that it is only the advanced version of S3 that has native DMX support. This doesn't present a problem if you're sticking with LOR only controllers or you're going to use the LOR iDMX but if you're thinking of using Tiger120, Ray Wu or David_AVD (Audio Visiual Devices) or other dmx devices via open dmx or compatible devices then you'd better be aware of this. i've been using the advanced version since I started with LOR so i don't know if you can select DMX channels but they won't be controlled or what will happen.
