Well, MIDI as a slow serial protocol sucks by itself-- but surey Microsofts vision of the modern operating system makes things whole lotta worse. The task scheduler doesn't really lend itself to provide realtime I/O and so called sophistication is actually bloating the system with unnecessary background tasks and add-ons not really needed for OS to function. You can also thank this sort of thinking for the many of the "Internet Threads" of today. Operating System for Audio/MIDI use should be optimized-- but for those defending "General purpose" OS concept: What has gone wrong, if MIDI jitter of the 300MHz PII is as bad as Current machines running 10 times faster? Moebius

It's for real. You'll have to use clock from the PIC to ensure SID register updates to be syncronized. Moebius

Hi- Would it be better to upload the MIOS itself before uploading the Application? ;) Moebius

Thank You, Thorsten for this opinion of Yours. I'll watch my mouth, but ban me as You find suitable. For all the audience, this Forum IS friendly, lets keep it that way. Moebius

Ok, I have to be positive. th0mas, Would this all has been avoided IF YOU had followed the rules given by eBay? Moebius p.s. For the others: A: - these things happen. B: - these happen for the careless (or IDIOTs as I call 'em) C: -know Your market and don't fool around.

I sent even more "IDIOT PROOF" reply I hope. /edit

It IS? Can't You see it from the scale? Moebius ;D

Hi. Your proposed way is a brute-force one, but I can't see anything wrong with it. I assume You'll have core powered from same source (common ground is the key) and button push will toggle DOUT. (I'm assuming DOUTs fanout isn't exceed, so it can drive led and one DIN input both) And You don't need an optocoupler here. [babble] This isn't of course an universal core interconnection model 'cause the mode is asynchronous and DOUT and DIN aren't working from the same clock [/babble] Moebius

Hi. If those are 50K linear sliders, those should work ok with no modification. Using pots with more resistance than 10K might introduce AIN jitter which is best fought using short cables between pots <-> AINs and AINs <-> core and maybe shielding. Connecting parallel resistance is a bad advice as this will result resistance curve to bend from linear response. Moebius

In another post You said "Wiki is lacking" and this sure is the case. Lacking is also a keyword here - there isn't much Wiki specific information yet. My small and stupid mind already has thought of better project specific introductions with "what it can and cannot do", modules needed ect., electronic parts primer, better module descriptions ect. --so I've been lazy. I'd say the fragmentation is mainly caused by lacking. I feel that important pagenames should be kept reserved as bases for more information and links to subpages. When the information get there, it should make it easier to read. Moebius

Yeahh.. 1. As Smash already pointed out.. Leds used for lighting aren't "critical" in such sense that they would need regulated voltage. That would just put necessary stress on regulator on the core. Those are best connected to power after the power switch with proper current limiting resistors for wallwart voltage. You can find "led resistor calculator" easily online. With ultra-bright leds, it's usually better to use (and test) much higher resistances than needed nominal maximum current for led. 4. Yes. You leave optocoupler out of the core where You connect the first core directly. Moebius

The time has come to make some changes in the forum. From now on ANY findings from eBay or talk surrounding online auctions should be directed here. Just take in the consideration that most items offered in eBay are one off or limited supply and auctions expire - the information is valid for a limited time only. Moebius

Thanks for the laughs! Although this time this topic is somewhat around the right place, where it belongs.. I'd be rather see these eBay matters discussed somewhere else than in the Midibox forum. I can see there are enthusiastic eBay shoppers here, but the recent flood of topics surrounding eBay findings simply pisses me off. Looks like it's a plague that spreads around forums. But hey, aren't we reading this forum thru internet access? It's as easy for me or anybody else to type http://www.ebay.com to my browsers address bar - I can find these things too, If I CARED! Now I can see such arguments coming as: "The others don't seem to mind", "Why are you so pissed?", "We are just helping other people". NO. You're unintentionally cluttering the forum probably in the name of free speech. So much of the recent discussion here has been meaningless and uninformative. For the small core crew of this movement who likes to babble and read others babbling: Get a proper blog - Link it here in the Misc and talk whatever You like. Those who like that will read blogs. Those who don't - Well, don't. Moebius

Sasa, It's 20 pulses per revolution. Moebius

No AINs are supported by MIDIbox CV (those are for analog inputs). If You mean MUXing AOUTs - SHX8 module is not currently supported by MB CV and it's also hard to find Sample & Hold chips used in it. Moebius

Would it be sufficient to define multiple banks in a such way that only part of the encoder/ button are changed and other parts are similar to the other bank? Moebius

No, It's not possible. Moebius

; Pots and faders are mapped to the "encoder" entries 64-128 Which leads me to believe pots are addition to the encoders. Moebius

Sounds good! Are You having "allright!" connections this night? Moebius

All the other pins are common. For 2 lcds on the same bus, see for 2 enable lines on the midibox schematics? Are there any? Moebius

I don't know - Try different enable pins for that. Moebius

So - good good. But wouldn't this post be more confortable at Misc section? Dontcha think.. like other eBay posts.. really..? Moebius

Yes - tact switches always are. Moebius

Any of those MAX232s are functionally equivalent for Your application. Temperature ranges are guaranteed "working conditions". Please folks, learn to READ datasheets before reading them and confusing yourselves.. ;) Moebius

Hmm. It's up to 8 motorfaders per core.. and I guess using midi feedback from the application to drive faders needs some "Control Surface Protocol" to be used. For non-motorized faders (MB64) 64 pots per core can be used... ect. Cubase SX can map those, YEs? Moebius
