We tried Harris knobs, but they were too long and would not fit the Skinner space = at all on the outside pedal row of knobs. I then tried the new Syndyne knob and found that they = are wonderful in operation and other than being ivory and black colored plastic, you = absolutely cannot tell the difference in the originals without a very close look. They are more = affordable then the first item I looked at as well. They are supplying most of the major supply = houses with the tab actions I gather, and I am sure they have a level of quality in their product = line. I did have one problem with one of the DK actions which was replaced quickly. They made wiring = harnesses and maps for me as well, the charge was minimal and saved so much work. Delightful to work = with.   I went with the Artisan system. I have the console done except for the new = replica nameboard and keyslips which OSI is behind in getting to me, but we expect to switch out = consoles during May. So far, the Artisan diagnostic programs are all functioning well and other = than not having immediate tech support they have been responsive to my questions. I usually have = questions answered by email the next day. The features the system offers are excellent, and I have = spent a great effort to get the console hardware correct and in the future if they want to replace the = relay system, the console will not need any redoing. We simply could not afford a Peterson = system which was my first choice.   The only negative comment I have received in my research was where a large = Johannus console was added to a large pipe organ and the Artisan pipe control system had to run = 70 some odd ranks through a midi port. The organist said there was a very slight delay that = was pretty well worked out and not a problem as far as she was concerned - she is a nationally = know organ composer.   Does anyone out there have any experience using Artisan equiupment? I = would like to know both the good and bad and what to expect as far as day-to-day operation? Since the = instrument will be controlled by computers, how do you prepare for the inevitable crash!! = There is plenty of room for the host computer in the console and I guess the program could be easily = uploaded if saved on disc.   Thanks, Randy Terry   __________________________________________________ Do You Yahoo!?

Doesn't the Artisan system use microcontrollers in the relay, with a PC being used only for making = changes in the specification?   That is what I recall from a visit a few years ago to Artisan's headquarters in Seattle. We had a fun time comparing and contrasting our respective systems and bemoaning some common problems, mostly related to limitations or awkwardness when applying MIDI to pipe organs.   Based on what I saw (and remember!), I'd say that there is little danger = of a "computer crash" affecting the relay system. Of course, = microcontrollers are little tiny computers, but their programs are stored in solid-state memory of one type or another and they typically do not depend upon the = use of general purpose operation systems that might be (perhaps) slighly less than completely bug-free. ;-)   Larry Chace

As soon as Easter is behind us, the old = cables will be cut and the new system will get its final hookup. All Artisan hardware is in place and checked out with their diagnostics. We will use Syndyne SAMs and pistons, as you are.   FWIW, we made the same choices as you, for the same reason. Good quality, and more functionality for the dollar than Peterson.   Best wishes, Ed.     ----- Original Message ----- From: "Randy Terry" <randyterryus@yahoo.com> To: "Residence Organ List" <DIYAPASON-L@pipechat.org> Sent: Friday, March 29, 2002 1:51 AM Subject: [Residence Organs] organ relays     > I went with the Artisan system.

(back) Subject: Pedal Contacts From: <Jadams4122@aol.com> Date: Fri, 29 Mar 2002 14:55:04 EST   Although the project for which I needed to add pedal contacts ended before = I actually assembled them I was going to use a home made optical switch. The = IR detectors (receivers) and the IR diodes (transmitters) each costs 19 = cents. The detector will drive the input of a 2803 driver chip high or low, = depends on whether you make or break the light beam and the 2803's will drive any magnet or could be scanned for MIDI. 2803's seem to be the most commonly used, inexpensive driver chip around, having 8 channels and costing about = 60 cents per chip or about 8 cents per channel. Therefore the "contacts" = would cost less than 50 cents each plus a little work. My mounting scheme was = super simple it all seemed to be workable but I just didn't need to do it after all. I would be glad to explain further privately and send a sketch. It = would be unusual but leaf contacts would of course be simpler. Just don't use something that turns out to be noisy like some micro switches.   John Adams
