Ooooch, wenn du grad dabei bist... mach doch mal noch nen Kaffee... ;D ;) *LOL* Nee, wenn das so ist, bin ich dabei. Hab schon eine fertige MB64, die ich sowieso demnächst mal auf PIC18 upgraden wollte. Wenn ich das schon mach, kann ich ja gerne Alphas ausprobieren, wenn du willst. Gib dir mal meine email über PM. PS: Das mit den 64 LEDs hört sich türlich sehr cool an. Multiplexed (sonst wären das ja zwei weitere DOUTs...)?

... in ...

Würd ich schon machen, aber bräucht erst noch die Spezifikationen (so ca.). Sprich: Wieviel LEDs, welche PCBs, wieviel (und was für) Taster usw. weißt schon. Damit ich das Zeugs mal zambasteln kann und die passenden PCBs noch ätzen kann.

"Styroflex 6,8n" 2,5% and 30 cent a piece (which is okay, I think). Theyre just a little big (16,5 mm long and 6,9 mm diameter).

OK, I´ll try those 2,5% styroflex ones. I´ll tell you then, how they work. Besides: Integrated caps are veeeery similar (the same with transistors - very low tolerance). I really do think low tolerance caps should be used there (within the partslist). Greets

Hab mich auch schon voll zurück gehalten... Pots da, PCBs fertig, Lötkolben heiß, Bestellliste geschrieben... 8) Aber blooooß keinen Stress, TK macht sowieso schon mehr als genug... ... ... seeeehr viel mehr!!!

- drunk -

LOL ;D

Nope. Not if you dont use a veeery compact design. And for that you need quite a bit experience. Check out how big other midiboxes are (on the UCApps site). 10 cm in the whole is a little to narrow, I think. Big problem: The cables! You have over 50 pots there, not speaking about the other stuff. Cablescablescables... :)

I´m a gooood, I´m a gooooooood  HARHARHAR!!! OK, just a MBHP God, but at least some kinda god. ;D ::) *happy pay_c* PS: Not answering was just a joke, but you understand why, don´t you? ... ;) /edit: why god? <- 501 posts!

The MIDI transmissions are relatively strong signals (I even could hear those unshielded ticks within my SID!). So pull the shielding of all MIDI signals in your box to ground (using shielded cables for all MIDI signals)! This should also be the reason why it only happens when you turn a pot (sending data). Greets

Hi there! I´m still over my SID. I´m going to change kinda little stuff until its finished at last (using TK´s PSU recycle & changing to 8580 & better ground shielding). Now I need new caps: When I built the SID with the 6581 I used normal ceramic caps ("Kerkos" in german). They should have a tolerance either like +/- 10% or 20% (lets assume the worst case 20%). The SID works with 12dB filtering, right? One cap for HP, one for LP, right? (I think so at least). Mathematics: About some filter formulas and so on, check your electronic skills!  ;D ;) SO: If you want a center frequency of 1000 Hz (in every SID & filter) the values with +/-20% can go from 833 Hz up to 1250 Hz (!!!!)! Is that the reason, why my 6581 filters sounded veeeery different from one to each other? Should be it! SO: Use low tolerance caps (like Styroflex caps - relative cheap & reliable, +/-2,5% (!)). Did anyone try? I will anyhow, but I just wanted to share this thought (and perhaps bring it in to the partlist of the SID). Greets & thnx for answers! 8)

"Heavy Duty foot mount" LOL - yeah right!! "High resolution: 1000 counts per rev" Cool, thats 1/8 rev. for going from 0-127 !! ;D Cool one!

I agree with UClaros. It´s not such a biiiig difference in building a small MB8 or the big brothers (there are just more modules connected). So starting with 8 pots is the most reasonable (reasons: UClaros). The only question what you have to decide is: Pots or Encoders! You should know the advantages/disadvantages. And they can not be exchanged to each other (pots: AIN, encs: DIN). You also dont have to make a 127-254 midi controller. 64 pots/encs are absolutely enough. why? Cause there´s a bankstick! Easily switch through CC#s 0-255 with four patches (first: 0-63 second: 64-127 and so on). HAVE FUN!!! One of the best pages you could´ve found about MIDI DIY!!! ;D

First the costs: It starts at about 90 Euros (LCD, 64 Pots, 32 Knobs, 32 LEDs) - all cheap parts like ebay or so- and ends at about 200-400 euros (big LCD, new pots, bought frontpanel,case,PCBs and so on). Naturally you *could* go up with the price to whereever. The design: If you value the price & time (especially the time!) which you have to put in there, making a veeery specific design like that should really be overthought well. You could also make a more flexible setup and use flipover-like transparent foils or whatever to change that whole thing to other instruments. Suggestion: As you will use it mainly for the mixing I would make 8 channels (not 7). This way, you can still do good mixing stuff, but your design is easily adapted to other apps. Perhaps even leave out those faders (theyre little expensive - if you dont buy the last crap). Hope I could help. Greets :)

Up to 8 displays!! ;D The MBDM (Midibox Displaymonster) is coming! Cool. Questions: So if we already have a seperated core to control the LCD, is it also possible to just bring that TV - idea back (normal data D0-D7 to PAL/NTSC)? And to bring back another thread: Color display possible? But thats more a point for dreaming, I think (cause the *color* data has to be sent by the MIOS Core anyhow - monochrome color displays would be a little ... ... expensive...)

All unused pot lines *must* be pulled to ground. Otherwise the PIC will be stuffed up working out that random data. Greets

right click & "Save picture" ;D :D ;D

:P ;D

Noch ne Idee: Leg mal nen Draht in die 7805 Pins rein. Und zwar so, das Pin1 und Pin3 kurz sind (glaub ich). Einfach nur, damit der 2200 uF mitfiltern kann. (Glaub zwar nicht, das das SOVIEL bringt, aber naja, nur ne Idee halt). Evtl. sind es digitale Störsignale - obwohl das bei nem Labornetzteil scho komisch wäre.

Maybe a big "what to do if it doesn´t work" - FAQ would be helpful, wouldn´t it? There are often questions coming up again and again (like that "I´m getting random data" - AIN question and stuff). Idea?

AARGH!!! :o *HAPPY* 8) ;D Even greater sound? *flippingout*...

1) no idea if possible, but if neccesary: If you start up the SID, this is the standard function of that enc right next to the LCD. If you want to switch to another Patch after sound programming just hit the menu button until youre back in the patch mode and use that encoder. So it´s not *reeeaaally* needed. 2) I think this could be possible, since you  would have some encs saved, which open up more DINs. But thats some programming, I´m not into. Already done & also quite useful: Use that built in button instead of normal buttons (e.g. The first enc of LFO also controls the LFO Nr. the second one the LFO waveform). 3) Certainly, thats to easy: Just mix down your SIDs to one signal and bring it to a log pot (it SHOULD be log this time) like that: ----POT---- |    |    | sig out gnd That pot should be like 10k or so. Easy to add. Not saved (just analog solution), but whatever. Greets.

Koennte evtl. ein ID Prob sein (hatte genau das gleiche Prob und das wars): Vergleich mal den ID von deiner Appl., die du hochladen willst mit der ID des PICs auf den du das draufhauen willst. Muss die gleiche sein, sonst passiert genau das.

Ppphhhhh *echt verwirrt* :P Kriegn ma scho noch... Was ich mitm Oszi gemeint hab: Schau mal nach, ob die Spannung an den Potis schwankt (die 5,5V). Sprich: AC auf den 5V ueberlagert. Ein Multimeter ist meistens zu traege um so was mitzubekommen... *nachdenk*... ... ??? >:( ???
