RE: lazertran paper the areas u dont print on come out white :)

Hi... Well, since gettin hooked lined n sinker with all things MBHP I have acquired too much stuff for projects I don't have time to finish. These control panels should be useful for any newb - or sumone who just wants to save some time! Note, I have consulted the MIDI Major TK on this and all is good :) http://notapplicable.co.uk/audiolab/mb_selling/mb_selling.htm Drop me a PM or email if ya interested... Peesh D

Whats up with using a regular encoder for ya scrubb wheel Steve? I do, works fine - just like the vpots :) Peesh D

Hi... I've got this schem done for the beats/smpte display on the LC/MC using 2 MAX7219's (as suggested on a thread from before as i remember)... Is it okay? If all is good I can test as soon as :) Best D

ahh, could be fine then if it was said by some1 who knows what they're talking about - i'm no experienced pcb maker by any means :P

u could try some cheap tact switch and stick some large rubber feet on em...

Hey Nomical... Not had this prob myself I must say... I just spray the pcbs after drilling with flux spray - seems to protect it nice and make soldering easier. If u wanted to go even further u could tin plate the tracks prior to this... Or, just cover all the tracks with thin covering of solder to protect em... If all components are already stuffed, I think u can still spray the track side with a protective laquer... Hairspray? never heard of that1 lol :P Best Dan

Found this site: http://www.epigraf.com/ Mebbe infra red control can be done with mbhp - but not cost the 495EU this module costs!! Best Dan

10 should be enough surley! :P Great to hear that it's possible - are u saying the timer thing i mentioned for the velocity sensitivity is also acheivable? With a few pointers mebbe I can make this work from my side, be a good one for other diy'ers... Best D

Nice work :) wish i hadnt slung the c64 keyboard parts out now :/ Best Dan

Great work T :D Can I use the new midio128 for that keyboard controller I mentioned a in a thread a while back? Basically, I have converted this old keyboard so that the key's act as switches on 2 bus bars (NO and NC). I was thinking I could connect the key switches to DIN inputs which would trigger the NOTE msgs, and then also have the bus bars contacts connected to 2 DIN inputs with perhaps a timer function implemented in mios (sumhow) so the velocity amount could also be calculated...does this make sense? Can this be done? Even a basic keyboard without the velocity sensitivity would do :) Best Dan

fairplay on this one - real nice :) but, arnt they a lil short??

Hey... Just started playing around in max for the first time on a 2d design I made in Illustrator...here's the results: The original design was done in Shaffer so the actual panel is how it'd appear for real :) Cost of around 150EU tho :P :/ Later D

Hey... Will it be possible to use just 2 7segment digits for the 'Assignment' display? Cheers...

likewise ere too :)

as promised, the short how-to: -- This short artical will describe how to set up the SID CS app for use with 2 additional pots - in this case for a joystick controlling the cutoff and resonance params... First off, make sure u have the latest sid_init.inc file (see the mios download section at ucapps.de) and copy it over the original one from the SID app .zip archive. Now for the .asm file editing. Open up sid_init.inc and locate these lines: ;; initialize the AIN driver movlw 2 ; use 2 pots call MIOS_AIN_NumberSet call MIOS_AIN_UnMuxed ; don't service multiplexer interface Pretty self explanotory - we are using only 2 pots so dont need any AIN modules, hence the UnMuxed setting. Now open up sid_ain.inc and locate SID_AIN_POT_ASSIGN_TABLE. Here u'll find the params u can assign to your pots. In this case as we only want to control the cutoff and res so we only need to edit it to this: SID_AIN_POT_ASSIGN_TABLE ;; every pot has it's own entry ;; no layer handling supported here! ;; up to 64 entries are allowed for various parameter values ;; Function name parameter menu offset cursor pos CSAIN_ENTRY CS_MENU_AIN_CHANGE_SYS, CS_SID_FILTER_RESONANCE, CS_MENU_FIL, 0x00, 0x02 CSAIN_ENTRY CS_MENU_AIN_CHANGE_SYS, CS_SID_FILTER_CUTOFF, CS_MENU_FIL, 0x00, 0x01 The table is listed chromatically inline with the AIN inputs so it's very quick to get a setup goin :) Thats it!! Build a new hex file, convert to syx and send to ur box...job dun :) -- Hope that makes sense :) Best Dan FAQMAKER

Hey Cem... I think the problem is in the encoding u used for the JPEG image.. Best Dan

:P Cheers Dan

heh,  3rd  edit... this time SUCCESS! :) surprisingly easy to setup...once ya use ya loaf :p Cheers TK! write-up to follow :) EDIT4... okay, this is workin and feelin nice :) i'm now thinking about the poss of extending the functionality by making use of a 'Learn' button (using one of the spare DIN pins) where u can assign any 2 params to the stick. Like the midilearn function on the ol' MB64. Doable? Thanks again Dan

Hey... I've got a 20x2 LCD for my SID CS and the backlight requires 4.2V. I've built a lil circuit around a LM317 to get this voltage. Now, as I'm running the unit from the C64 psu and have TK's optmised config, where can i take an appropriate VOUT and GND from this to feed the LM317 psu? Is taking the + and - from before the 2200/25 (which is 12V) a right way to go about it? Or the the + from there and GND from the +5 line? Cheers Dan Edit: took the + from before the 2200/25V cap and gnd from the +5 line which gave me 17V. Fed this to the LM317 circuit and all seem fine...backlight workin...for now ;p

U still up for this TK? Cheers Dan

Hey cem... Thanks for infos :).... In regards to web space for ur files...how about the portal? Isnt that one of the purposes for it? Failing that, i'll stick it on my space - even knock up a simple page if need be, or have u got one sorted alread? Best Dan

wow :D, stunning design!! - which kicks of my first bout of Q's. What app(s) are u using to create such renders? Autocad? 3dsmax? I take it all the components in the image are the same dimensions of the ones ur gonna actually use too...? With such a design, are u able to take a dxf/cad file format to get the panel cut to the exact same dimensions etc? I really want to be able to transfer my ideas into realworld renders such as these which I can then take further and build too!! 2nd, are you using a mbhp core for the keyboard key scanning with the MIOS code already written to handle the input notes? I've tried to make use of an old 5 octave commadore kb but with no success based on another project using a PIC. If it can be done with MBHP core and some dins then great! :)... Inspiring stuff fella! Congrats :) Dan

:)

Hey T... I havnt done any asm editing as of yet, I've just worked out how to rescue the button/led brds on my LC ...long story! - so i'm gettin this done as a priority ;) Should only take a day at the most... Cheers Dan
