Thanks Digineural, I'll try this right away!

Hi everyone! I'm working on an unfinished project I got from a really nice person from Germany. He gave me lots of ol' school stuff (DIN, DOUT...) and a CORE v2 with a PIC16F + SID module v2 with 6581. I managed to debug it and test it without a LCD (it was fried), and I was able to play the basic SID patch with a midi keyboard. But I wanted to get more out of it so I bought a 18F452, uploaded the bootloader with my PIC programmer, made the mods (crystal, connection to pin22 changed to pin 28), installed the chip, connected the two boards following this schematic, connected a 2x16 LCD, tested voltages, and then uploaded MIOS1.9. Everything worked fine : CORE communicating in MIOS, LCD working fine. Then I used the testtone (OK), and the interconnection test (OK). I connected a bankstick, and I uploaded the SID 6581 .hex file. Everything went well again. At restart, the bankstick was formated, and I heard the launching gimmick from the SID. But then, nothing more. Just a sort of phantom, very light clicking noise when I play notes on the MIOS keyboard. Each time I start again, I can hear the gimmick sound, but I'm stuck with it. I haven't connected the CS for now (I'll go for the minimal CS, option A), but I thought I'd get a basic sound even without the CS... I tried to upload the patches through sysex, but it doesn't seem to work, whereas formating of the bankstick seemed to work. (I also noticed that the 6581 tend to get quite hot in its middle after a few minutes, but maybe that's normal...) Any suggestions from the SID masters are welcome, I wouldn't like to make a permanent damage to the SID... Thanks!

OK, so it is possible that my DOUT module cannot work on its own if a AOUT module isn't connected?... I've got a scope but I'm not very good at using it... :-/ We agree that Gate is normally 0V and switches to 5V when triggered, right?... I double-checked my wiring, everything is in its place. And the rest of the MB Sequencer works like a charm. This is puzzling...

I'm on AOUT* Channel 1 Actually I don't know how to do that... I don't have a connected AOUT card so it appears as non-available (AOUT*). Does it still work for a connected DOUT? Why isn't there a DOUT choice on its own? Here are the voltages on J1 of my DOUT card at Midi Seq startup : Vd : 5V SO : 5V SC : 4,5V RC : 5V Weird...

OK... Doesn't work. I've got continuously 5V on each DOUT...

... And if I also want Clock Out, which I could configure for 1, 2, 4th, 8th, 16th?... :rolleyes:

Great! I'm going to try that right away. I finished the wiring, as you can see. And you can have a good laugh at the sight of my unplugged AOUT module : I'm still not sure about how I want it powered... :rolleyes: (it has been in there for 3 or 4 years!!!)

Cool, thanks. I'll do it right now and see how it works... Then I have to edit the MBSEQ_HW.V4 : I just have to copy the above configuration that you wrote in your old post above, right?...

You mean the adjacent header on Wilba's PCB, labeled J2, right?

OK, safety first, I'll use the DOUT module. I already have a DOUTX4 so it shouldn't be too hard. One thing though : My sequencer is Wilba's design, so there is already a ribbon cable (J8 + J9) going to the control surface PCB. So I have to make a new cable to connect my DOUT module in series, right? And what do I have to do about shift registers?... :unsure: Thanks again...

Sorry, but I don't think I get it right... How do I tell my track to open Gate 1 from the CORE module? And what about Gate 2,...? And what about the clock?... Thanks in advance, I'm lost...

OK, not a CC track then ? Just a "normal" track?

OK, great! And the CC value is #16? And then, which value (0-127) is to be entered on the steps where we want the trigger to trig?

Hi! I'm afraid I need even more clarification... I'd like first to use the gates / clock from the CORE (STM32). (I'll use a DOUT module if this isn't enough for my needs) If I get it right, this is already enabled in MBSEQ_HW.V4. I've connected a 1/4 jack to Gate1 + Ground from J5. Now : How do I configure my track to actually use this gate 1? I have to use a CC track, right? Which output do I choose? (I only see Midi OUT, OSC1-4 and AOUT*(I don't have an AOUT module connected yet...)). Which value do I enter to actually trigger Gate1 on my steps?... Yes, I'm THAT far from understanding the concept... ;-) Thanks in advance!

Thanks ! I'll have a close look... Cheers, Gaël

Pleaeaeaease help meeeee! :sad:

Hi there! I'm experiencing some trouble with my Quicksilver modded TR-606: it is laaaate! You can really hear it. With Logic if I set the midi transmission to -36 ticks, it is OK. Can this be done with our beloved SEQ V4?... Thanks in advance! Gaël

UP? Can I control start, stop and change songs with my Samson Graphite 49 MIDI keyboard?... Thanks to you all! Gaël

... Still... :-) I am now trying to use my Midi Keyboard with its numerous pads and pots to control the MB SEQ. I would like to be able to start, stop, change songs... from my Midi keyboard (it has pads for start, stop, preview, next...). Is this really possible? If so, how? Thanks, Gaël

Hi everyone, I have this issue on one of my songs : I have a mixer map on position B2 saying that OUT1 CHANNEL3 volume is set to 35, but it doesn't work while playing the song from the start and volume of OUT1 CHANNEL3 (OUT1 is my MB6582) on position B3 is loud (127). However, when I just start the playing on B2 (the mixer map step), it works and volume is down on B3. Also, if I go to the mixer map and change volume (which is 35 but plays like it is 127), I works and drops down to the correct value... I even tried to add a volume CC to the track itself on the pattern, using layer D to control volume and setting it also to 35, but it still doesn't work while playing the song from the start! I really don't get it... Any clues? Thanks! Gael

Hi, Thanks for your answer. Unfortunately I'm pretty tight on MIDI ports... I think I'll just duplicate a track for the moment and wait for what the future might give us... ;-) Cheers!

That's funny 'cause I did exactly the same a few months ago, also using the MXR schematics. I have a single stereo input on one side, and on the other side 2 mono outputs (convenient to plug it to a mixing console) and a stereo pot to control the amount of noise gate reduction. It works really great and it is very simple to achieve, as jjonas said! Of course, it is a bit tricky when dealing with sounds that have important gaps in volume...

Hi everybody, I'd like a specific single pattern to be sent to two separate midi channels, for example OUT 1, channels 1 and 2. The idea behind this is to play the same part with two of my MB6582 SID engines to get a fatter and slightly chorused sound... Is this possible? Thanks in advance!

That is great. Thanks once again Thorsten! All the best, Gaël

Hi there ! As an RC-50 user, I am quite curious to know how your experimentations went, Duggle... I'd also like to be able to change songs on the MBSEQ when I change patches on my RC-50. But I've always heard that the RC-50 was being very inconsistant with MIDI... The ideal thing would be, from my point of view, to be able to keep the MBSEQ as Master but still being able to send a CC message from the RC-50 to the MBSEQ when changing patch on the RC-50, telling the MBSEQ to switch to a specific (matching) song... No need to fire the song / pattern in my case as I start songs with the MBSEQ itself (actually I added a footswitch controller to start-stop songs / patterns so my drummer can do the job... All the best, Gaël
