hello, great thats what I was hoping was the case but just wanted to make sure I didnt fry anything :) thanks for your assistence im off for a weekend of learning to compile code and burn my fingers... d

Hello all, just wondering if someone a bit more electrially minded than me could help me out..... I am assembling a CORE module and have problems getting hold of the bridge rectifier. Someone recently advised me on the discussion board to use 1n4001 diodes as attached in the schematic, but nowhere local to me sells this diode either!!! The lowest number both of my suppliers have is 1n4007, do you think it would be ok? Kind Regards in advance Dave mK

great good to see that sparked a bit of interest, payday is still a couple of weeks away but straight after I will try and get one in the post to you. If anyone beats me to it let me know, I of course am already thinking about 4 stacked up on top of each other.... teehee soon D mK

Hi TK et al, following the sequencer threads with the greatest of desire but in the meantime I may have an idea.... I have noticed here in prague many places selling replacement screens for NoKia phones, rather cheaply. If I was to supply you with one does the offer of writing drivers still stand (or are you busy with taking over the world!)? kindest regards D mK

Hi all, BTW payc thanks for your message re the rectifier from my previous topic. Another question for all, I cant find anywhere details of the connectors as used in various ucapps fotos (ie the lcd page) for ribbon cable. I have lots of sil headers but no connector for the ribbon cable. Does anyone know what they are called so I can find them in my catalogue? Regards Dave M

Hi all, So I got my 1st PCBS from mike, currently Im buying the remaining parts to populate them and have run into a few questions: Listed in the core module parts list is a "A bridge rectifier for 40V/800mA". However both of my local parts shops only sell what seem to be quite large rectifiers. The smallest spec I can find is listed with the spec "Bridge rectifier 1.0A / 100VAC DIP4 -+WW". Does that mean anything to anyone? If this isnt suitable the core module page mentions using 4 1n4001 diodes to achieve the same thing, can anyone on which is better? Secondly I am hunting after LCD screens (like everyone else I guess!). I have found a company called eio in america, they seem to have been around for a long time, has anyone here used them or got any feedback on them, they really have very cheap screens and the postage to Europe isnt so bad.... As ever thanks to you all for the help, I should be tweakin some knobs before the summer at this rate :) Regards Dave mK

hi all, so after months of waiting i have the cash for ordering from mike in germany!! just wanted to check that people are still satisfied with his service etc, I guess no news on the forum means good news? lookin forward to asking lots of silly questions soon ;) Dave M

allo y'all, well you may have noticed I have been less active on the board recently, i used to have free high speed net conection but due to unforseen circumstances i now have no net :( But anyways i fianlly have the money to order my PCBs from mike in germany. From memory you need to send him either cash (not willing to do this because i lost 600 pounds worth of dongle in the post last month, even though it was insured and to be signed for!) or do an international money order. i had planned to do this but I found out over the weekend that the Czech Republic (where I live now) is one of the few countries in the world that cant do internationl money orders to germany!!!! So does anyone know of another way to get mike the money? Ideally I would like to use Western Union transfer (expensive BTW but my only option) but my german isnt good enough to be able to ask him via email. anyone have any suggestions?? other than that hello to all of you in the MB community, once i have these PCBs and a few other bits i can start causing some chaos with my ideas for a MIOS sequencer ;)) Regards Dave mK

Hello all you electronics fiends ;-) so I'm about to obtain my PICs and realised that I may as well get some bankstick chipz as well. But they come in a few packaging types which I've not heard of: PDIP 300mil SOIC 208mil SOIC 150mil Can anyone explain which of these would be best because i havent bought IC's since I was a kid!!! Thanks in advance Dave

wow so it works then!! I have looked at your old posts a few times and have been asking around for old mouse donations (everyone wants an optical mouse so I might have 32 encoders!!!!)........ Keep us posted (no pun intended) about how its working because one of my obsessions is recycling old teknology for fun projects like this ;-) D

may I just agree with all of you about the net being about escaping the clutches of the massive corporations!! Tk you generosity has inspired me build controllers which I could never of dreamed of designing or buying.... I cant wait to play with motorised faders, sids and a million ledz ;-)) I'm looking forwrad to the sequencer source..... Regards to everyone who replied to this post!!! Dave

Allo stryd, Well its nice to see that I'm not the only one interested (or is that obsessed!) with slightly off the wall sequencers. I think this is an appropriate palce to discuss sequencer ideas, I've not time to detail my plans today as my net access is limited at the moment..... But I will try and explain some of my ideas over the weekend and as long as TK and the rest dont mind maybe we can keep the dialogue here on the site so others can join the discussion? I look forward to bouncing my various weird ideas off you ;-)) Regards Dave ps am I correct in assuming the code snippets as mentioned in your mail will let us use a library of mios functions so that I wont have to spend 6 months studying asm code?

Allo TK, Well first let me give you the olibatory congratulations on MIOS, I've yet to test it but look forward to all those cute new functions.... However as per usual I have a question!!! I am most interested in a MIOS sequencer and would like to implement some slightly "weird" functions ;-) The MIOS progress bar shows that the sequencer will be open source. What will be the development procedure? I have been trying to learn C++ but have a basic grasp of concepts so i'm happy to learn a new langauge...... Once again a thousand thankyouz for helping us musicians with little money build those professional boxes we all crave :-))) Dave mK

Hi Ian, Thanks for your encouraging reply, I have quite a bit of breadboard lieing around so I'm off to find parts and "give it a go" soon! If I get really stuck I know I can rely on this friendly community to give me a hand :-) Regards Dave mK

Hi Thorsten, I just re-read my last message, I realised it wasnt very clear - my only excuse is that I have had flu all week ;-) What I would really like photo's of is the componant layout for circuits of the MBHP on verobaord. I have some experience of electronics but even tho I have tried to understand lodemaster (the veroboarder software) it would great just to download the circuit layout of a pro like yourself so I can copy it on veroboard. I think this is also what the starter of this topic was thinking..... Regards (ill) Dave

Hi Thorsten Now I know that you must be extremely busy (I read the mios progress chart, very impressive!) but I wonder if you coulld at some point post pictures of the mb hardware you have built on veroboard? It would really help out those of us who are trying to go down this route (and who cant afford pcbs eyt ;0)) Regards Dave (broke!) mK

Hey Mr T, Well as ever your detailed responses solve all of my dilemmas, thanks i can sleep easier when I know there is someone to answer all my geeky questionz ;-)) I plan to build a unit with the buttons for menu's, the sfb buttons and then 16 buttons (which as I understand it control my sequence steps). I understand the LCD is essential, as a matter of interest I can source very cheap replacement screens for a n0ki@ mobile phone. Would it be difficult to implement support for such a screen within the firmware (I have seen them used in a diy MP3 player projetc on the net...). They are very cheap and easy to come by ;-0 I have looked at serges software, it seems like I should be able to program a sequence from the software and then play it back from my minimal MB64. Is this the case? And if so then I think I could set my IBK (yes it is a nice toy!) to edit either CC controllers ro even sysex. Well by the time I work all this out in my head I may even just be able to afford the encoders any hows, but its an interesting way for me to try and understand the MBseq. So have fun Torsten and thanks again for such a nice open source project.... D

Hello again! I have been saving up for rotary encoders etc etc. Last night I realised (!!!) that I already have a midi controller with encoders and lcd bars above each knob to give feedback on the value. Its called a 10 control and the details can be found here: http://members.aol.com/uwekeinki/ So now I am contemplating building a MB64 with sequencer firmware but without any knobs! Can someone tell me if it is possible to use serge's software editor to setup my patterns in the sequencer? Then for performance can the MB64 deal with incoming midi controller messages (sent from my current controller) to edit key parameters of the sequence (eg track mutes, overall control of note length etc etc). If so then I will be a very happy man as I can start building a cute little box this weekend ;-) Kind Regards and happy knob twiddling Dave mK

Hello all, I was wondering if anyone has devloped their MB64 on veroboard? Yes I know PCB's are available but money, as the song goes, it too tight to mention ;-) I have the lochmaster software and did consider converting the schematics into an uploadable image to help others who may wish to develop on veroboard (or stripboard!). But I have a feeling from Thorstens image posts about the new MBNG he uses veroboard as well.... So before I embark on reinventing the wheel I was wondering if anyone wanted to upload some images of veroboarded MB circuits? Regards Dave

Hi all, I have tried to get a scheme together for building my MB64, I have decided to use the gerber file on the old MB64 page because I presume it has all of the AIN, DIN modules built onto one board. I did try to download a gerber editor but I am on a slooooow link at the moment so I cant downlaod the Eagle ediotr etc. Could someone who is familiar with gerber files etc confirm that the file uder "Alternative PCB's" on the page http://www.ucapps.de/midibox64.html will get me a PCB made with all the modular parts needed for a MB64seq unit? Thanks in advance Dave

Glad you liked the idea, I think it will work really well. What would be important is how well the lcd can display the variables the encoders will be changing because there is obviously no feedback from the physical knob position. Anyone using the current MBH64 with an lcd care to comment? Regards Dave ps Thorsten do you manage to find time to do all this incredible development and hold down a "regular job"? Â ;D looking forward to MB NG.... where can I find some more details?

hi thorsten, I just noticed today that the mb64 firmware is split into sequencer and controller... And I was wondering would it be possible to configure the software to use the full sequencer facilities (they sound great!!) but rather than build a 64 pot box just use rotary encoders and a switch to "jump" the encoders between the various sequencer channels?? Just wondering ;-) regards Dave mK

Cool thanks for the quick response! I know it would be nice to have an LCD but I am saving this for my MBHP construction. For the time being I just need this simple unit and therefore its good to know I dont need another dsiplay. I will probably be back with more questions soon!!! Regards D

Hi guys, Well I'm still lurking here keeping an eye on what is going on! A quick question though, I want to build a very compact unit without LCD etc which can take in 8x 5v triggers and turn them into midi notes. I have looked at the older midibox hardware and it seems possible to run the unit without a screen. Can someone just confirm this for me? Also is it feasible to build the MB16 and progrma it from Serge's editor and therefore not even have to hook up an LCD at all? Well kind regards Dave M
