To add sound activation scene chase functionality to MyDMX, how would you want to see it implemented? You'd need to make your scenes and then drop them into a chase "maker'.
I think what people are looking for is something a bit beyond what MyDMX is going to handle.
Paul C wants to have static scenes that can run while other scenes operate. Sounds like a Compu Show/Compu Live application to me. Sound active? I know Compu Show handles that.
People need to do as much research as possible before buying into something. People also have to realize that MyDMX, at it's cost, is competitive with other products in its price bracket. Yeah, there's some pretty cool free stuff using cheap hardware for an interface, and yes some of it is rock solid and reliable. But, when you get into a jam or need to ask a question, where's your support? Why, you get what you paid for: zilch.
Many people buy MyDMX expecting it be the "ultimate solution for their needs". It's a great product, no question. But at the cost, it can't do it all. You have to keep in mind that MyDMX was designed to be easy to use and mainly for a DJ to use quickly. That isn't to say it's a dummy product, because you can do a lot of stuff with MyDMX, especially when you invoke the FX generator.
ADJ isn't the first to offer "feature limited" versions of their products. It's actually more common that you realize. I have certain data comm products where I have to use activation keys to unlock features and functionality. It's there the whole time, but I have to prove I'm allowed to use it. That's just on some hardware. There's a security platform where you can buy a base serial number, which on its own can determine what functions are available from the get-go. If I need more features, I have to buy additional keys. In other words: one code base, but many different product service offerings. Roland with their Sonar product offers in in various flavors and costs, however, these are more like scaled down/up versions depending on what you are purchasing. ProTools is similar with their M-Powered, LE, HD and TDM platforms, although those tend to also be further restricted by the hardware they attach to.
I suppose ADJ could do something similar with MyDMX, but why bother? Jump over to Elation with the awesome Compu Show package.
If people want their sound active stuff, then just buy dimmer packs and pop them in switched mode and put your sound activated fixtures on those. Problem solved.
As far as building in sound active functionality into a fixture, first, it's been done. You have sound active fixtures, so there ya go. But, now you're asking if sound active can be added into DMX traits? Sure, it's done all the time, many fixtures support it. Want a sensitivity control? Been done too. But, I think the question is can a fixture that has sound active functionality but lacks a sound active function when in DMX, can such a fixture be modified so as to support sound active in DMX mode? Sure it can. All you need to do is learn how to program a ROM for the fixture and you're all set. Then you get to make your own profiles for use with MyDMX, which if you're willing to do the effort to make a ROM, spending 15 minutes making a profile is no big deal.
Now, as far as a company such as American DJ offering such upgrades, I'm mixed about this. Overall, I feel that such functions should be available in DMX mode if you make the fixture have a sound active mode for non-DMX usage. Offering a replacement ROM? Sure, that would be great, even if at a cost. I also think the price of anywhere from $50-100 is not an unreasonable cost that many users, myself included, would be willing to pay to get such functionality. But from a product development and ongoing support issue, it is sometimes more economical to simply develop a whole new fixture, as odd as that may sound.
Regarding "take it or leave it", that's how the industry works. "Here is the product, there ya go". And then someone like you examines the product, sees that it's something you like, but then you have this not so unusual requirement where you want a sound active function in the DMX traits, and the fixture doesn't have it when in DMX mode, but has a regular sound active mode. You got two choices: buy it or don't. Either way, you have a right to your opinion, and saying stuff along the lines of saying that you really would like to see sound activation(with a control channel) in DMX mode for that fixture is something that marketting and sales should be listening to.
You're not the first to complain about this, and it will be a while before the last person complains about this. I have been left with the impression that ADJ is listening to customers wants and needs and desires and is doing things to try to help satisfy the needs of the customers. That's just good business.
Pulling back to MyDMX vs. Compu Show:
I have both. I am also learning Compu Live and will learn other Compu products, despite Compu Show being the flagship product. Just because I am running Compu Show, I still keep MyDMX installed and functioning. It works fine and has a genuine application and purpose in my rig. I'm sticking with MyDMX, I like it for my band shows for now. But, for my theater-type shows, Compu Live is where it's at.
