Ok, let's sort some things ... You have successfully burned the bootloader. The id 000....0000 is ok, as long as you don't use a LTC Module. Now you have to sysex the MIOS1.7 in MidiOX (you must start to SysEx in 2 seconds after power up). After that you can SysEx your application. hope this helps DOC

Just to make some things clear ... If you mean the TK floorboard design. You can only use a PIC 16F for this design ! If you like to program your own floorboard applikation with MIOS you can use the PIC 18F. I'm almost sure, that you can not burn the 16F firmware on a 18F PIC ! You can burn every PIC for about 10000 times, I think greets DOC

The best performance is with a 2x40 or a 2x20 Display. For more info look here: http://www.ucapps.de/midibox_sid_cs.html greets Doc

You can be very proud on this ! greets Doc

Still strange ... BUT A GREAT DESIGN !! 8) 8) STill have no real idea on your problem. Just trying a litte bit around ... Do you have still the noise, when the regulators are not mounted to the chassis ? No ?!. The chassis has ground connection via the regulators. Another test: Do you still have the noise, when the display is not connected to the core ? - This just to eliminate any connection from the LCD to the chassis. What happens, when you connect the chassis of a mounted encoder to ground ? Do you have the noise still, when NO midi connector is connected and perhaps with a headphone at the audio out (just to eliminate any extern loops) good luck ! Doc

Hi Seppoman, I don't understand what you mean with "in-between" thing. Can you explain a little more ? For the encoders: How did you connect te ground line of the encoders. Did you connect all encoders together on one ground line or did you connect each encoder directly to the din ground ? By the way... if you don't connect the chassis of the encoders to ground there should be no problem with them in touching the front panel, or ? Do you hear the hiss in the audio line of the SID ? What amplification after the audio out ? Did you short the audio in ? greets Doc

Hard to answer with this pictures ... First of all: the 10,5 V AC ar ok ! Your regulator is a 78L09 ? The 18,1 V: Did you measure the 18,1V under load ? If not: Try to measure under load. For example with a 10K resistor as load (connected between ground and the 14VDC pin). Another thing: What is the type of your bridge-rectifier ? greets Doc

Start with 1A min. 500mA doesn't make sense in your case ! greets Doc

Hi, yes it's possible.... I've build a 8x Interface some time ago. Just take 4x the USB Module and connect it to a USB Hub. Voila ... you have 8 Ins and 8 Outs. I've put all modules and the USB Hub in a 19" Case 1HE. It's surely not a cheap way and you should look if a ready unit isn't cheaper. But you asked if it's possible .... greets DOC

Hi again, the flickering is a sign for too much current ! (Typical behaviour when your 7805 is regulating down). As you said, when you connect your DIN Module the flickering starts. So your DIN Modules need too much current (by fault). Again. Try to measure the Current after the regualator. Measure it with/without DIN connected and tell us the values. You have to use the DC A of your multimeter and please measure between the output of the regulator and the board. greets Doc

You need a dedicated midi-port per box. No other use of the midi-connection is possible Doc

Sorry 'bout this... if you don't want to build - you have to buy it! But you're not able to buy a Midibox SID - you have to build it ! greets DOC
