Thanks Tk, That opens up a whole new world of possibilities. If I understand you correctly I would just follow the example of "SEQ_BUTTON_ALL "in the code and duplicate it for the fuctions I want to shift? I haven't given it a try yet, Im still in build mode. I'm not code savvy so it'll probably be touch and go with this I've got another question. Is the 7 segment bpm display, and gate outputs, like those in V3 doable in V2? -D

Hello all, Currently building a V2 seq using a 452 pic I already had laying around. I want the unit to be minimal with only one 2x40 lcd and eight encoders, eight leds, and rows of eight buttons. I understand that with a single 2x40 display tracks 9-16 are displayed when a button or encoder is activated for one of those tracks. Can I get the leds and encoders to shift from tracks 1-8 to tracks 9-16 as well? Is there some kind of shift button I include in the code to do this? I'm not very good with code, so simple is the best policy. -D

Thanks again Lyle. Your input is very helpful. Now I just gotta find the time (and brain power) :P to get this code thing down. Unfortunately achitecture studio (CU) leaves little time these days for fun hobbies like this. I'll do more reading at some point so I can get this project where I want it. It'll be a while, but I'll post my progress with this to help out others in the same boat. Thanks, -M

After copying seq_bpm.inc and seq_led.inc from mb808 stock into the include folder for clockbox and changing the bpm digits#defines then build I get nothing. I also changed the dout shift register in the clockbox main.h to 4 to avoid problems, still nothing. I'm still going at it, but am just as lost as ever. -M ???

Nice. But where do I paste this mb808 code? In the main.asm in the output folder for the clockbox? Thanks, -M

If this works I'd also like to add 7 segment lcd series to display song position. ;) (but one thing at a time of course). -M

Well they're wired according to http://www.ucapps.de/midibox_seq/mbseq_v3_bpm_digits.pdf, but can be moved around the doutx4 as needed (it's a plug). Right now dot thru g is connected to J3 and the common anode is connected to J4 at D2. The source code is === BPM digits === ; ; set to 1 or 2 to enable the 3 optional BPM digits ; 0: BPM digits disabled ; 1: digits with common cathode ; 2: digits with common anode #define DEFAULT_BPM_DIGITS_ENABLED 0 ; ; define the shift register to which the segments are connected (0=disabled) #define DEFAULT_BPM_DIGITS_SEGMENTS 5 ; define the shift register to which the common pins (cathodes or anodes) are connected (0=disabled) #define DEFAULT_BPM_DIGITS_COMMON 6 It's located in the setup_808_mbseqv3_tk.asm. I need this functionality but I understand much more is needed to make this work for me. Also I'm using a 18f452 not the proper chip for seqv3. -M

Wow. I have no idea how to properly program, so this might be a stretch. I've built the appropriate connections for my 7 segment leds but still lack the code to make them useful. I was thinking of somehow borrowing some code from the MB808 project because it already has a BPM display. Any suggestions, such as copy and paste or some kind of version of that? Otherwise I'll just go with the clockbox as is. Thanks, -M

Hello Midibox world, I'm currently building a clockbox and would like to encorperate three, 7 segment led digits to show bpm. I've looked around and have tried a couple things but I'm pretty lost. The dout works along with the din as the project works fine as is. I realize some code will need to be added, but from where to where is the question. I will continue to try, but any help on this would speed things up considerably. Thanks, M

Yes, the synths needed gates. The M/P didn't need any special cables, but the Source did on the trigger input. The MBCV is all done and works great. This was a pretty smooth build with little complication, thanks goes to TK and company. Next up is the sequencer. :) -M

Hello all, I got the midibox CV using an NG module up and running today. Good news is that it works great with my Moog Source so far. Bad news, or strange news is that it dosen't trigger my Korg Mono/Poly correctly. If I hold down a key on the M/P and play a sequence of midi notes thru the cv box it works(pretty lame though). This of course is not acceptable for many reasons, and I've tried all sorts of internal settings on the MB CV with no luck. :( The M/P is not complicated, it uses V/oct so I hope it's something simple. Also, I want to build a simple MB Seq using one 2x40 lcd and a few encoders and buttons that have multiple uses. I think I had seen someone working on such a thing but couldn't find any examples of the code that was written for it. ??? -M

Hi Guys, Clockbox almost ready for a case but the code still needs alittle tweaking, if possible. I'm trying to sync a Linndrum LM-2, EMU Drumulator, and a midified, heavily modded TR-606 with this clockbox. The midi out works great with no problems into the 606, but the others require clock signal. The Drumulator's clock input can be adjusted to different incoming ppq so it too really isn't a problem. The LM-2 on the other hand needs specifically 48ppq to run at the correct BPM. My question is, can I change one of the midi out's on the clockbox to send 48ppq on it's own without changing the master BPM clock divider? (I've found the divider in the BPM menu for the clockbox and changed it with no results). Also, I can use the J14 output from the core to run either drum machine, it works great (with the drumulator atleast). Again, I'm not a programmer so some specific suggestions would really help me ;) M

Wow, that took a bit more sorting on my own but I think I've got it. After all the installs and path stuff I edit the original code with notepad++, replacing the original file. Call up cmd in run, plug in the text provided along with my app directory hit make, and boom, It works. An altered HEX file that MIOS Studio sends to my core just fine.

First off thanks for the response John, I'll try to be more clear. I downladed and installed sdcc.exe but I'm lost after that. I looked for a program similar to MPLAB but did not find it. I'm a programmer so I really do not know what to look for past that. The code I got is from the forum topic "clockbox in slave mode". I'm thinking that it is a modification of main.c so I'm just trying to build a new HEX file with this new code along with changing my encoder types. I load all the files main.c says to include and I get no source file error. I obviously am doing something completely wrong. -M

Hello everyone, I'm sure the dead horse has been beaten enough about this subject but I too need some help. I'm somewhat familiar with MPLAB as I've used it to recompile code for my MBSID. Now I'm building a clockbox and want to tweak the software to fit my needs. The only problem is that I've never used SDCC. I've D/L'd the files and tried to open the sdcc DOS looking file but it dosen't stay open. I'm assuming that's what I need to do to alter the code, but again, I'm lost. I've tried to use MPLAB to build the new code I've got from the forums but I get source errors. Any and all help is appreciated!

Hello Midiboxers, I have already built a working MB SID with a minimal control surface, but would like to build a strictly 303 style interface so I can use my sid as a bassline. I'm sure there's a thread that goes over the details, so if someone could point me in the right direction I'd greatly appreciate it. I'd like it to be as close to a simple bass line sequencer as possible but have enough flexability to be able to program reasonably easy. Thanks!

I have the newest edition of the software. Just dosent' seem to work. I'll try again. Thanksfor the info. -D

Well. looks like I fixed the wierd on/off problem with the leds. Now I just get one flash upon start up, nothing at all or all on the a few seconds and they go out. But they no longer go out when I pick the unit up. As far as MPLAB goes, I downloaded the dout_enc_n1_3 and attempted to open the MIOS Skeleton Small.mcp under projects and it will not open. It says that the file is not recognized. I tried a fresh download and still nothing. I have also tried changing the pin configuration in the code from D0=0, D7=7 to D0=7, D7=0. This is really [move]frustrating[/move], I could do with, or without leds, but I've already installed them in my box.

Well, got my MBSid all boxed up and are ready to put some leds inaction for a few encoders I've installed. (mbsid cs B+) Well I thought I had everything under control after I soldered everything up and then programmed the code for the appropriate leds. I turned on my box and no leds lit up. Everthing else worked fine. So I took an led to see if the polarity was wrong, and it was. So I swapped the connections for the leds and now they stay lit all the time. Whats funny is that if I lift the box about an inch from the table all the leds go out. The same thing happens when I place it in my lap. Hold it about 1 inch above my lap and no leds work. So.... is programing the code for the leds the same as the code for the encoders and buttons? I thought I saw something about using pin#7 as 0, #6 as 1, and so on. Seeing as how I'm only using a step b+ control surface I need to customize all the extra button and encoder functions to do specific jobs (cutoff/res etc..) so I also need the leds to do specific functions as well. The pcb is clean and everything seems to be wired up good. HELP! This is the last step in building my MB Sid! Thanks-

Thank you, I got it now. Now I'm figuring out how I should do my buttons and encoders on my dinx4. I got a board from smash so it dosen't give the same points of attatchment as in the schematic here. I'm guessing I can just start at J3 and start attatching from D0 to D7 on each bank to J6 and some how properly assign each button and encoder. -D

Hello all, I got my MBSid rockin' now. I have built an dinx4 to attach to my core to give me some controls. My dinx4 works fine, all the buttons and the encoder seem to give signal to the core. The problem is using all of my 2x40 display and of course assigning the 10 buttons and the encoder/select functions. I've looked all over the forums to figure out what I need to do with no luck. I know the code needs to be changed but that's about all the info I've found that I understand. Looks like I need a step-by-step tutorial or something. I've never written code, but not afraid to learn. I hope someone can dumb this down a bit for me. -Thanks D

It's on j9. What do you mean by application? It's a sid.

My core and sid pcbs and 2x40 lcd are working fine. Now it's time to add some control. I build a dinx1 with all the appropriate parts. I tested the voltages across the ic holder and got 5v. I plugged in the ic and turned on the unit and I get nothing that tells me the cs is working. I attatched the step a cs to the board and rebooted, still nothing. Am I missing the bus? I've search all over this forum and found noone with the same problem that had a explaination on how to fix it. I'm using smashes boards and BSL 1.2b MIOS 1.9e. Help- -D

Oh yea, I got a Mono/poly also. Would LOVE to midify it too! :o

Got any specifics for a rookie? My P6 needs some lovin' I just don't want to screw her up. Thanx
