On my setup the cookie that stores what has been read and what has not gets corrupted about once a week, resulting in "new" tags on everything. Don't know if this happens to others. Clicking "mark all posts read" on the main forum page clears it up for another week or so. Best! Smash

I'm sorry for your attitude also. Looks like you might have just found a way to insure that you don't get any further help. A few posts like this and the people who post any kind of help will disappear. I know you are frustrated but don't take it out on us. Use that energy to find yourself a cheap DMM and learn what you need to know to understand the instructions that have been graciously laid out before you. Might be time to call your "sponsors" (are you building this commercially or to get a passing grade in school via another persons work?) and tell them that you could not find anybody who thinks DIY means do it for you. Don't make this a hostile place. SmashTV

Don't worry Iain, despite my joking around in this post the JDM isnt going anywhere soon. ;) I'm still selling them, and they still work great for all but a very small few builders. As usual it's always thier problems that people post about here in the forums, not thier success when it works on the first try. Best! SmashTV

How about a photo gallery on the portal? I set one up for this at gallery->MIDIbox photos->Technical->Wiring.Go here Technical:Wiring to add/view images. Have fun! SmashTV

While the JDM is troublesome for many it also works very well for many also - older PCs/older versions of windoze work best. Here in the forums people always post when they have a problem, but rarely post when something works as intended. That makes the success rate of the JDM look much worse than it really is. ;) Have Fun! SmashTV

Don't know about the broccoli programmer, but I'll put the floorboard firmware on a PIC for you for free. :) The floorboard is one of the old school MIDIbox projects, it uses a PIC16F877 and does not use MIOS or the bootloader. Everything is burnt to the chip all at once, no sysex upload etc. No MIDI in needed! There is not a kit or dedicated PCB for the floorboard, but it could easily be built using a slightly modified (leave off some parts) CORE board. Have Fun! SmashTV

Hey All! The portal is definitely a work in progress, and hopefully will always be! There is no direct upload for anything but pictures, this is for security reasons only. Seems uploaded script exploits and SQL injections are a favorite passtime for the script kiddies. :( But don't let that stop you from adding to the portal, anything MIDIbox related can be hosted there (and some things that are not, see the "SideProjects Forum" for non-MIDIbox projects by MIDIbox users.) Just send an email to me at portalmail@avishowtech.com (or my regular email) and I'll get it up on the portal asap. Board layouts, MIOS apps, build photos, everything is welcomed, even unfinished stuff because it spurs development from others! Have Fun! SmashTV

Whoops my bad! I don't know where my head was posting about that and not including Admir's awesome eDrum! This buffer circuit is based on Admir's input design, and the MIOS app to use it is a work-in-progress that has not been released yet. Best ;) Smash

You are right about the A/D conversion on only one pin at a time thing. You have to remember here that it is only reading one -pin- at a time, doing that you don't have to wait for settle time (or other waits) that add enough to the time overhead of multiplexing to make it unusable for this. If the reading from the pot is not as real-time as possible, the fader will overshoot enough to cause the motors to overwork, so you would have to bring the move speed way down, stealing more time away from other processes (still working on a move that should be done) etc. Have fun! ;) SmashTV

They could be multiplexed, but there are several reasons not to, the best one is that there is a tradeoff in performance to keep the motors response fast.Multiplexed inputs are read one at a time. If fader 1 has a fast move in progress and MIOS is off reading another pot when it's stop time for fader 1, the fader will not hit its target accurately. Keep in mind that most moving fader designs use one processor per fader to keep up, TK's design is pure genius. :) Yes but that is for driving RC model servos, not reading the "servo" track on the faders.The term servo is used to describe a lot of different types of designs, but usually just means a motor with some type of positional feedback to its controller. Have fun! ;) SmashTV

Hey all! The new Core boards are in, take a look: New documentation for them is on my Core info page. The are available for worldwide shipment from my MIDIbox store. Documentation for the brown boards (V2) is here and won't go away. Questions? Comments? ;) SmashTV

Time for a loopback test throught the CORE I/O, From the MIDI debug page: This and the other tests on the MIDI debug page will let you know if your optocoupler is the problem.... ;) Best! SmashTV
