Tested at the TLV5630 pins and got very erratic readings. Have to shelve this for a little while because I want to play my new Midibox Seq, thanks for the help TK & Latigid_on. I will keep you posted when I get a new IC to try.

The voltage does not change at any of these pins on the TLV5630, I've tried running the seq and adjusting the calibration control in CV Configuration while monitoring. Values I get are 12. 4.20v 13. 4.20v 14. 4.20v 15 4.20v 6. .17v 7. .32v 8. 4.20v 9. 4.20v Ref (Pin 16) is at .02v I can toggle the three pins CS, SC, Si at core J19 using MIOS terminal and get 0v and 4.6v on each with testaoutpin 0 and 1 I also tried a LPC17 core using a new SD card and config with the same results and no Aout_NG action I'm lost, usually things go very smooth with Midibox stuff

So this is what I learned from Latigid On's post and how I wired it. I confirmed it with the wiring in tutorial 016 for the Aout configuration: Still does not work. I am getting CV gates, clocks, and triggers over the line drivers from the Dout SR's but no CV from the Aout_NG. I have tried at the core on J19 and over the line drivers and nothing, just 10v or so from the outputs. The lack of system clock at J19 makes me think this is a configuration issue, but i have CV gates. There is no SC at pin PB3 on the Discovery board.

Can anyone help with the wiring from core J19 to J1 on the Aout_NG PCB? Does it wire up to the S0 row or the S1 row of J19? I'd like to try that first before I wire J1 to the receiver module. I have a new IC1 in place on the core, I'm going to see if I can get J19 on the core talking to the Aout_NG module this a weekend. Thanks for the graphic Langid on George

Can you be more specific where the non-standard pinning occurs? is it core J19 <--->J19 transmitter board or J1 Aout_NG to receiver board or both? Does anyone have a graphic of the correct pinning? George

It looks to me like there is no activity on J19 from the core board. On pins 9 + 15 of IC1 on the line driver transmitter board I have clock type activity on the scope, on the same pins on IC 2 (associated with J19) I have nothing. I've checked the solder connections on the core board so now I'm looking for a 74HCT541 to swap into IC1 on the core board. I think I'm on the right track here.

Thanks for the quick reply TK. Fixed the CV gates problem, noob error, I was checking D0 for Ch1 gate when in fact it appears on D7 of J3 on the Dout module, so this verifies the Line Drivers are working OK. Now moving to Aout_NG trouble shooting.

Thanks TK. Now for my main problem, no CV and CV gates on Doutx4. Should the file "MBSEQ_CV.V4 file" be on my SD card if I have made the configurations properly, because I don't see it there. I have set the CV module to Aout_NG, set the OUT in Menu/Event to Aout and set the CV_GATE_SR1 to 3 in the MBSEQ_HW.V4 file. I think this is all the setup I need. Also should J5A/B/C be enabled it is in my config by default

My initial problem was being unable to access the CV configuration menu, menu pages are just something I can't find information on how to access all. So I made a shortcut to CVCFG in the mbseq_hw.v4 file, replacing SYSEX for now, I have a green light on in the Aout_NG module, after doing the setup for Aout_NG. My new problem in CV configuration is obtaining 5v for note C3, I can only adjust to a low of 8.4v. I'm using +/- 15v. power supply, that should be OK, so now I'm searching for the problem.

I have all the necessary parts installed to use SeqV4 for CV, gates and triggers via the Line Drivers. I think this line: First edit the config file on the SD Card to use the AOUT_NG (i.e. #define AOUT_INTERFACE_TYPE 3) and save it ! from the Aout_NG configuration instructions has been replaced by a menu configuration as noted in the config file: # AOUT interface now selected in CV Configuration Menu and stored in MBSEQ_CV.V4 file # please scroll through the menu to find this page! Can someone confirm this? The problem is, I can't find this Menu item, where is it located?

See the hookups for SeqV4 users on the Line Driver page, this is the suggested usage if you use a Line Driver module with Seq V4. Line driver. Also you get a BLM port on the Quad IIc module, available at Smash TV, this hooks directly to the core connector J4A

Ah, thanks you for that, confusion reigned for awhile here, now it all makes sense George

Hi, I'm in need of a DOUTx4 pcb, it needs to be the latest version which is R5 Thanks George

I just need a DOUTx4 PCB, I see SmashTV is sold out, hope he gets some more. I see your DOUTx4 has 8 IC's, the photo at SmashTV shows 4 IC's so he must be displaying an older version. Thanks for the post again, very helpful George

Thanks for posting this, it's what I had in mind. The CGS93 trunk line modules certainly is going to make it easier. Where did you get the CGS Panels? The SEQV4 in red looks awesome btw

NIce job, I'm just about to embark on the V4 build, so this is very timely, it's great to see it all come together for you. I'm going for a more standard unit with 1 Midi I/O and 1 Quad IIc. I do have a BLM-TPD on the way though, so your build certainly gives me ideas in that department. can someone give me a link to this tip? Thanks

Have a look at this link for a bi-polar supply. The one you posted does not have a common ground and has different regulators, the regulators you mention are for 12v supplies.

Received case today, very well packed, thank you.

I was trying to pass the PC through the LPC_1769 core, USB --> midi out, not record it, like a midi interface does.

I'm trying to get a program change midi message to pass through my SeqV4L using Abelton Live, but it's not happening, all 4 SeqV4L ports show up in Abelton, and note values/timing clock do pass through. I've tried sending on all midi channels, only thing I see on the Midi-Ox at the other end is a pitch bend, any thoughts of what I might be doing wrong?

PCB's arrived, thanks again

PCB's received, thanks

PM sent, thanks!

I'm interested in a pair

I need the back panel for the MBHP_CORE_STM32F also and I'd order from Julian as I have in the past. So the panel set needs an option for the rear panel only to acccomdate those of us with a front panel already.
