    I was called into an elementary school to mic a bunch of budding actors for their school musical. I went in a few weeks ahead of time to see what they had to work with. Quite some time ago, their entire sound system was renovated and upgraded to what seems to be a very versatile system wired around a "RANE RPM 88 Programmable Multiprocessor." Unfortunately, anyone familiar with the upgrade has been long gone, and the current personnel haven't a clue as to how it is wired, programmed, or used!!! I figured out the basics, but still have no idea how the mulitprocessor is configured. I do know that there are some EQ and compression items involved that I wish weren't there for the show.
    I went to the RANE site online and found the manual and its "DragNet" software "QuickStart manual, but when I went to try to download the actual software, I got a message, "No longer supported." I called the company and spoke with someone who confirmed that they had stopped support of the software the week before!!! I explained my situation and asked if they had an archive copy that they could supply, but got a very terse "no" response. I called back the next day and spoke with someone else who gave me the same answer. (I find it hard to believe that they wouldn't save an archive copy for future reference...)
    I finished the job by completely bypassing the unit to achieve the control and sound that I required to do the job, but the school still wants to be able to understand and control the system's options. I've been asking around to friends working with other sound companies to see if they have a copy of this "DragNet" software designed to program the RANE RPM 88 Multiprocessor, but to no avail.
    So I am now opening up my search here to see if someone might be able to help me land a copy of the software to further investigate the school's system, since they don't have any budget to re-do their system again....
    Thanks in advance for an leads you might be able to supply.

    Looks like there are some archived versions of Dragnet at the link below. Of course, you'll need to find the appropriate version compatible with the firmware on your RPM 88.

    This is why it's so important to have quality name brand equipment installed in places like this. At our high school (11 year old installation) both the lighting console and the dimmer rack are "no longer supported." And apart from me (the husband of the drama teacher and volunteer tech director), no one at the school has a clue as to how anything is "wired, programmed, or used!!!" Just replaced the lighting consoled with a used ETC Ion. This way, if I'm no longer there, any outside person they bring in will have a quality, familiar product to work with.

    I'm not sure why you think Rane is not "quality name brand equipment". Manufacturers discontinue equipment due to a variety of reasons, like non-availability of key parts or lack of demand. It would be interesting to know what the brand was of the lighting console you replaced or if you just hadn't heard of the manufacturer. An installation that has been around for 11 years is not really that old in the grand scheme of things. Almost anything can be repaired if the parts are available somewhere.

    Please forgive me if I unfairly slandered a quality manufacturer.

    Our old lighting control system was a Marquee console by Horizon Controls. The manufacturer is no longer in business and minimal support is now provided by Pathway Connectivity Solutions (I believe) and you can still download the software and fixture libraries (last updated in 2011). The problem is that the system required an external 32-bit windows computer to run (not compatible with 64-bit OS). As the 11-year old PC running the system was showing signs of imminent death, it didn't make sense to try and find/build a 32 bit computer to "fix" it.

    The thing I really like about the ETC is that anyone who comes in knows exactly what it is and what to expect. "Well known and predictable" is good for an environment like a school where technical expertise can be minimal and fleeting.

    Popularity of specific brands does truly speak volumes about the longevity of a product, especially in a niche market as what we work in. Grafik Eye, for example, seems to have been installed in every building I've worked in because they were all remodeled in the late 90s and therefore I know how to operate the controller.
    But that doesn't mean products that were less popular makes the product any lower quality or not "brand name."
    The RPM 88 and other Rane products were quite revolutionary in their time.

    RANE is definitely at least B-list pro audio gear. :)

    I had the same problem with the same unit at a local house; it wasn't wired in, already, but I was hoping to put it back up. Didn't go anywhere.

    Like it or not, RANE DSPs are not commonly installed in pro-grade audio systems. That being said, DSPs in setups like this are typically "set-and-forget" systems. It sounds like someone wants access just "Because" they need access - and likely lack a valid business reason beyond a need for control. I'm speaking from a long list of experience in working in school settings with "Tech guys" who are "experts" on live sound/lighting/whatever. I'm a huge proponent of correctly configured systems that support longevity of the system, but I'm also a supporter of only having a valid reason to go in and change things. Without knowing additional details of the system, though, it's hard to say if that's the case here.

    It's funny you mention the 32-bit issue. I did some consulting for a church many years ago that was insentient upon keeping an old Windows 2000 machine alive in order to access an old DSP system. While I agreed it was necessary for the short-term, it was eventually necessitated to get a system that was more appropriate for the sustainability of the facility, and keeping around an old DSP from the 90s just wasn't a good idea anymore.

    I don't disagree with your view, Aaron.

    My stance was it's here, let's see if anything useful can be done with it, and if not, I'll just go back to ignoring it.

    It's a *system processor* that likely functions as a crossover, pass band limiter, routing (matrix) mixer and zone controller. It might make breakfast, too. ;)

    Unless the sound system has problems that cannot be attributed to other causes (blown speakers, dead power amps, faulty cables, microphones that went through a flood, etc... I'd not suggest you get inside it. It's also likely that if you succeed in finding the DragNet version that matches the firmware in this unit, it's still password protected.

    Not disagreeing here. :)

    +1 here too. Like I mentioned, sometimes people (and I notice it a lot at schools and churches) like to get in these things just "because." I'm not referring to the OP here, but rather the random teacher, tech guy (who really doesn't know the first thing about sound systems), or volunteer. Unless there's a problem though, leaving it be is probably the best bet here.
