Hi Graham,
I agree with what has been written here. I only know LSX is passing, but it's one of (what seems like many pieces of) software built upon work done by Lennart Weitzski who wrote LDS while he was a phd student in university. Lennart did an impressive job as a student, but I don't think his goal was to create easy-to-use software that could be instantly used by unsophisticated users. (Not that I am saying that you are unsophisticated, but the starting point for all software development should be to ask the question "who is your intended audience".)
The goal of QuickShow was to do exactly what its name implies -- allow people to create laser shows quickly. Moreover, the intended audience for QuickShow is people who have absolutely no experience using a laser and can't even spell the word "laser" correctly (i.e. people who spell it with a Z). On the other hand, my impression is that Lennart derived LDS from his observations of the Lasergraph DSP and our LD/QM32 system -- both platforms intended for experienced laser users.
QuickShow has an easy-to-use abstract generator. However, one thing about the abstract generator is that it is truly unlimited. You can keep on adding oscillators, modulators, and color modifiers. There are no limits here. But it is still simple and -- moreover -- all abstract work I know of requires a lot of experimentation, something Swami clearly has time and passion for.
Since the title of your post is "LSX or FB3", well LSX is software, while the FB3 is hardware that can be used with several pieces of software. As such I'll transition this discussion to other software that is usable with the FB3.
In contrast to QuickShow, we have BEYOND, which is software intended for experienced laser users. In addition to what QuickShow has to offer for abstracts, BEYOND includes many more sources for the "base shape" in the Abstract Generator from QuickShow, and many more modifiers. BEYOND also adds the "Abstraction" generator included in LivePRO which was derived from LAStudio and then expanded. And BEYOND can play (but currently not edit) all abstracts made in the LD2000 series of software.
One thing to keep in mind is that all of these sofwares are only tools, and there are no such thing as good tools or bad tools, only tools that would be applied appropriately. QS is designed to get people going quickly, but as our lowest-priced software intended for unsophisticated users, there are limitations that are purposely imposed to avoid confusing people. LD2000 and BEYOND (and in my opinion LSX) are intended for experienced users. The learning curve for all of these is steeper. However, BEYOND is built on the user interface philosophies of QuickShow and so the learning curve should not be so hard for people to go from QuickShow to BEYOND.
Graham, please contact me privately to discuss this further. I want to make sure all people who use Pangolin software and hardware are happy with their purchase decisions.
Best regards,
William Benner
PS: If you haven't already done so, check out some of the abstract shows in the Pangolin Shows Portal, including Tom Sawyer. I think the work done by Mike Dunn at least rivals what Swami does. Both Mike and Swami are experienced abstract creators, and so by looking at the shows, it will illustrate what these tools are capable of, when given experienced and passionate users with time on their hands
