  2. midiphy SEQ v4+

    thanks for your reply. right.. twelve was said in the video. it's certainly a bit exaggerated with the 16 ports but i'm using expert sleepers at the moment with 16 midi out and thought of a simple switch box that allows me to determine for each synth whether it gets its signals from the computer or the hardware sequencer without moving a cable. guess eight outputs will be enough anyway :P
  3. midiphy SEQ v4+

    I think an external expansion will be possible for the Seq V4+( as it is ), there's already too possibilities to connect it, the Line Driver and the MCAN... I will build this seq too, and try this expansion once I've got it, so go for this sequencer! 16 MIDI outputs(and more) will come after. Best Bruno  
  4. midiphy SEQ v4+

    Thanks for the kind feedback!  I'm not sure where you got 16 MIDI outs from? The max here would be 8 (MIDI8 + I2C). There is a possibility to use a second I2C with a firmware hack to gain 4 more, but for space and latency versions this wasn't included in the standard build. @Antichambre is developing a 16x16 MIDI expander but again it doesn't fit in here. Another thing I can think of is hosting a GM5x5x5 or the newer chip, but it's also not in the plan nor complete at the moment. Of course you have 8 outputs with 16 channels each, so plenty to work with using the 16 sequencer tracks. What was your plan with 16 MIDI outs? CV/gate would go through the DB-25 line driver. On the other end AOUT/DOUT modules are required (under development, some solutions already available).

    Luckily, I ended up here again. :D That unit looks fantastic. when i think of the panel wiring on my seqv3 wich was my first diy project about ten years ago :) ... I'm in is it possible to build it with 16x midi-ouput and 8x cv-gate or do we also have to use the expansion port for additional midi outputs if you want more than eight? thank you!!! in reverent expectation

  7. Starting MB6582 build

    Just wanted to drop this link here: http://midibox.org/forums/topic/14564-building-the-mb-6582-control-surface-photo-tutorial/ It’s a bit hard to find over in the “Tips and Tricks” forum, but is an excellent resource on putting together the control surface part of the MB-6582. I followed this guide almost exactly.

    It is. One of my first DIY-attempts. Would have gladly bought it through this community instead. But that didn't seem to bee an option any more.

    Thanks everyone for the informative feedback!   Decided to go with power option E and 8580s only. Really cool solution with the PCB-panels! When I saw it I had already ordered case and panels from http://thebeast.co.uk/ though. I have (finally) gone through the BOM and created my Mouser shopping list (can be copy/pasted here https://no.mouser.com/tools/part-list-import.aspx):   512-1N4148T50A|100 688-SKHHDT|50 604-WP424HDT|115 652-PEC16-4220FN0024|15 313-1250F-100K|4 161-MJ355W-EX|1   575-11044640|5 575-1104762841001000|10 502-PC722A|1 502-57PC5F|2 550-20301|4 710-860040478015|1 710-860241375002|10 647-ULD1E101MED1TD|1 647-ULD1H010MDD1TD|10 75-2C20X7R334K050B|1 581-SR215C104K|38 75-1C20C0G330J050B|8 505-FKP2.022/63/2.5T|16 581-SR211A102JAATR1|16 594-K471J15C0GF5UH5|8 858-36FR10KLF|5 264-10K-RC|10 610-BC337|1 512-BC547BTA|16 859-6N138|1 579-24LC512-E/P|8 595-SN74HC165N|5 595-SN74HC595N|11 579-PIC18F4685-I/P|4 774-ATS10A-E|4 511-L7809CV|1 532-577202B00|1 532-574502B03700G|1 919-R-78B5.0-1.5|1   660-MF1/4DCT52R5601F|100 660-MF1/4DCT52R1201F|100 660-MF1/4DCT52R1001F|100 660-MF1/4DCT52R1002F|100 660-MF1/4D52R1000F|100 660-MF1/4DCT52R2200F|100   Doest this look OK? Any suggested changes? Correct ICs, transistors? I went for longer lifespan electrolytic caps. Any opinions on those? Better options for the SID filter caps ( 505-FKP2.022/63/2.5T )?     I'm leaving the fan out. Got these heat sinks for SIDs and PICs. Might be too tall... How much space is there between the PCBs?:  https://www.ebay.com/itm/8pcs-14x30x8-mm-DIY-fans-cooling-Heatsink-Aluminum-Profile-Cooler-With-Tape/123021408514?ssPageName=STRK%3AMEBIDX%3AIT&_trksid=p2060353.m2749.l2649 https://www.ebay.com/itm/12pcs-10x35x10mm-Extruded-Heatsink-With-Thermal-Tape-Aluminium-Profile-For-DIP/112681555348?ssPageName=STRK%3AMEBIDX%3AIT&_trksid=p2060353.m2749.l2649 Also ordered this dirt cheap display.

Thus I wasn't sure how big a heat sink is needed. So I got two options and plan to mount the biggest one I can fit into the space between the PCBs.

    When I am pressing the Button addigned to LoadSnapshot, the MiosStudio is indivating in the command window Snapshot xy is loaded from NGS file however it seems that all the loaded parameters are 0 or there are no loaded parameters. It seemsbthat at the loading of snapshot it reafs the values af all ainser, button, etc When I am pressing the button assihned to DaveSnapshot the MiosStudio does not indicating anything. IS THAT OK? When I am opening NGS file it seems that there are saved some informations.
  11. MIDIbox Quad Genesis

    Glad to hear of your interest! The front panel is definitely a big hurdle. I have two versions of this project for those who want to do something but not build the front panel: MIDIbox VGM Player and MIDIbox Genesis Tracker. However, it sounds like these two might not have the functionality you're looking for. There is no version which provides the complete synth engine and all the capabilities but not the whole front panel. The controls exist to edit things and give the user feedback about them--having all of this stuff editable from menus would not only make it very difficult to use, but would require a lot of changes to the interface software. It's not too much of a stretch to say that the synth exists primarily to be a set of nice front panel controls for messing with the Genesis chips. In retrospect I understand that this made a high barrier to entry, but this is the box I wanted to build. The aluminum is a major cost, but it is not strictly necessary--since the whole front panel is on one large PCB, you can just use that as the front panel, though it's not as nice. If you would like to go this route I can gather interest and have another round of front panel PCBs manufactured, and sell you one for a reasonable price (under $100). There would be about 10-15 hours of soldering things (like the 638 LEDs) onto it, but that's all pretty straightforward. (And since you would not be using LEDs which have to be ultra-bright to shine through the translucent plastic, you could use cheap LEDs for all of them.)  All that's left after that are the Genesis modules (which should still be for sale on the MIDIbox Shop--let me know if they're out) and the core, all of which are not very expensive or time-consuming. If you don't want to do this, I would suggest you build MIDIbox Genesis Tracker and control the synth from your computer. I had a working build of this firmware at one point, but I've since made lots of changes to the VGM module API and not updated this project, so it won't work as is--but if you want to do this I would be happy to get the code working again for you.

  13. dipCoreF4 and dipBoardF4, a compact Core.

    In mios32_config file add : #define MIOS32_DONT_USE_IIC and the pin of J4 will not be initialized as I2C. Then initialize the pin as Input e.g. PB6 GPIO_InitTypeDef GPIO_InitStructure; GPIO_StructInit(&GPIO_InitStructure); GPIO_InitStructure.GPIO_Speed = GPIO_Speed_50MHz; GPIO_InitStructure.GPIO_Pin = GPIO_Pin_6; GPIO_InitStructure.GPIO_Mode = GPIO_Mode_IN; GPIO_InitStructure.GPIO_PuPd = GPIO_PuPd_NOPULL; GPIO_Init(GPIOB, &GPIO_InitStructure); Finally to get value: u8 value = (u8)MIOS32_SYS_STM_PINGET(GPIOB, GPIO_Pin_6); Best Bruno  
  14. dipCoreF4 and dipBoardF4, a compact Core.

    thx! so PB6-J4A.SD PB7-J4B.SD for example? fine do i have to change anything in mios itself - or is it done in the main app/mios.config file? (i know J5 and J10 are GPIO labeled on standard core docu - but J4 is for IIC)
  15. dipCoreF4 and dipBoardF4, a compact Core.

    Hi Phatline, You can use the pin you want, all pins are GPIO as first function. Just don't take something already used(SDcard, midi, etc..). You want input then don't use 5V level output pin(SC, SO, RC) like the one of J19 or J8/9, they can not be input. But you can use J4 for example. Best regards Bruno
  16. dipCoreF4 and dipBoardF4, a compact Core.

    hey i am working on a new project "Konga Trigga", and i want to reuse the DipCoreF4 for that again... since it is really handy i need 3 Digital Inputs (used as Trigger inputs  -  feedet with Schmitt-Trigger Digital Signals)   i dont want to connect them via a slow shift register - since it is trigger > it is time critical. As far as i can see i can use J5.A0(PA1)  +  J5 A1(PC5) > and set them in Mios as Digital Input, makes 2 so only one Digital input left - is there any other Pin i can use as DIN? (LED.1, LED.0 for example?)   User.Butt (PA0) > is for Bootloader Switch  - maybe that one?
  17. MIDIbox Quad Genesis

    Hi Sauraen and All, very impressive work, WOW i'm itching to build one, but this gigantic frontpanel making it so impressive also scares and restrains me from doing so... It seems that building the frontpanel takes around 80% of the overall effort, cost and time, blowing up the project to a size too large to fit into my spare time and hobby budget. Also the panel itself... so far, i did my front panels from scrap sheet metal on a drill press (+little rework with jigsaw and file), but with this layout, that way would take forever, so the only realistic option is to buy the machined part, again boosting the price.. Did you (or someone else) already consider a "lite" version with the same sound engine/functionality but much less IOs for guys like me? Would it work with the current software to omit some of the buttons/LED and access the functionality/information otherwise? As the SID, where everything can be accessed with the minimum control surface and all other stuff can be installed as an option.  What i would like to build is not the absolute minimum, but something in-between. Full functionality as a standalone midi synth, a set of buttons/display/enc to give access to everything plus some additional ins/outs for better access to only the most important features/params. No LED-Rings, no frequency display, no vu-meter.. do you think, this would be possible with your project, or do i need the full CS to access everything? in case it works like this- -which LEDs/Buttons/Encs are absolutely necessary? -which ones would you recommended to install? -which do you use/like most? (only practice can show ;-)) -which are less important?   best regards simon

    I have deleted the NGS file, now it seems that it is saving something however  at the loading it is sending all the Sender values to the assigned CC but it sends all 0 value. It seems that the LED parameters are saved correctly but not all. What is the right procedure for saving and loading. - Is there any good explanation of this procedures:Save, Load, Dump -Which parameters are saved/not saved, loaded/not loaded: LED 0-4096 , SENDER 0-4096 , BUTTON 0-4096, no_dump=0/1, active/deactivated ....... I need to understand the mechanism to be able to program it correctly however there is not enaugh information about that. Frank

  22. Starting MB6582 build

    Hello Hybris, I made one of the first of these, using 8x 6582. A couple of thoughts I'd like to throw in: - I didn't use any LED standoffs.  Never had any trouble.  Just put the LEDs loosely in the PCB, then screw on the front panel ... carefully turn the assembly over and all the LEDs just kind of fall into the front panel holes. Get 'em snug and solder.  The leads are fairly rigid and should hold them in place. - The front panel top-right "L / R" LEDs will collide with top right screw hole in the PT-10 case, so you need to grind a bit of it the plastic away. - The weakest part of the design (IMHO) is the way the two boards connect together.  I used very short flex cables.  Others have used individual wires, ribbon cables, or pin headers and sockets so that you can take the two boards apart.  But there's very little clearance between the boards, so you will just kind of have to live with two boards that don't come apart.  (I would love to lay out a new panel board someday, with all the shift register ICs and resistor networks on it, which would connect to the main board using only about 5 wires.) - The rear dual-gang feedback pots really can enhance the sound.  Do not buy cheap pots for this.  Slight movements can change the sound a fair bit, so you want to be sure that the paired-up pots are equal in value and taper.  Buy brand-name for this application.  I put cheap pots on mine and I regret it because I try to turn them all the way down but the left and right SIDs sound a little different from one another.  I may replace mine with 3-position toggle switches (i.e. no feedback, 50% feedback, full feedback).  I wish this could be made programmable somehow, using CMOS switches or digital pots or something. - I have a fan and guard in my case.  I couldn't get the motor noise out of my audio, so I disconnected it.  That's the extent of my thermal management.  It has never overheated. - As mentioned above, don't use the C64 power supply.  I still use one.  It works OK, but my MB6582 has chewed through 3 separate Commodore bricks. That's right, I'm on my fourth.  Back in the 1980s and 1990s, my C64 probably also outlived 2 or 3 power supplies, so they were never particularly reliable. I understand the European and Australian power supplies are a bit more robust than the North American ones. YMMV - For the front panel, I did the JB Weld / standoff method as Wilba documented very well.  That stuff is amazing.  I haven't had a single standoff let go of the front panel, and there are no visible screws.  I cleaned, then roughed up the surfaces of the back of the panel AND the standoffs using a wire brush or sandpaper prior to applying the fillets of JB Weld.  Not sure if that helps make a stronger bond, but it certainly can't hurt.  Also you need lots of clamps, and lots of patience. - Next time I have mine open (soon, because I've got a flaky encoder or two), I plan to wire the 8 audio outputs so they also appear on the DB25 jack.  Eventually I'll be able to use a single cable to connect my external box with 8 VCFs, 8 VCAs, AOUT and active summing and proper volume control (which the MB-6582 lacks).  In the meantime I'll be able to use a snake like this: https://www.proaudiola.com/product-p/8-m2932-db-ts-2-p.htm ... Think about that panel mount DB25 connector, and what it can do for you.  You can even use it for power if you like. This is an awesome synth.  I hope you have lots of fun with your build, as I did.

    Most probably the problem is that I can not call section from section. I have tried several other cases and it seems that in some cases it is not possible to loop sections or call a section from another. But in some cases it works. Interesting. But I have moved forward to final step. It is saving and loading snapshots. At first I have had a feeling that it works however it seems that it is not loading or storing all the information. If I have changed the no_dump parameters after storing of some snapshots, is it needed to reset the ngs file? I need some clarification: 1. What is the difference between the LOAD and DUMP command? 2. What the No_Dump command makes with SAVE, LOAD and DUMP commands? 3. Are the deactivated Senders saved and loaded from the NGS file? There is what I exactly need: 1. Save all selected LED, BUTTON, SENDER actual values 2. Load them from the NGS file, but without sending any CC values or triggering the forwaded LED, SENDER, just change the values 3. I need to save and load also not active SENDERS which are deactivated by set SENDER:xxxx 0 4. Than there will be a procedure written in NGR to activate and send all parameters   Frank  
  28. Starting MB6582 build

    Figured this might be a good thread to start on, I have also just purchased PCB's from Modular addict (the MB6582 Base and control surface), a case and panels from The Beast and a C64 replacement power supply from Amazon as although I intend to use 8580's for the initial build I woould like to keep things open to the possibility of using 6581's in the future. I am guessing the next step from reading the above is to grab a scrap c64 board to cull the power din and the rocker switch ? Additionally I did find this place selling heatsinks for SID size chips https://www.retroleum.co.uk/c64-repairs-and-mods
