Hi,
Thanks for the offer, but I got one last year.
It's sitting nicely next to my TPD ;)

Hi Steve,
Glad to hear you are better, and up for some MIDIboxing :)
I am not sure what the R3A version of the Core Module looks like, and what wiring you refer to, but an important modification that needs to be done for the MBSID_V2 is the resistor and diode for the CAN bus. It's showed here http://www.ucapps.de/midibox_sid/mbsid_v2_communication.pdf
It sounds like you are planning a Stereo SID, so you need to have a look at this as well .http://www.ucapps.de/mbhp/mbhp_8xsid_c64_psu_optimized.pdf
Not for the PSU or the Multicore, but for the connections to the Left and Right SID modules.
Hope that helps. Good luck, and feel free to ask if you get stuck, I'll try to help.
Where are you located?
Cheers, Hal

It was an interesting experiment anyhow.
Yes, of course it works :smile:
But if the STM32F4 Discovery board is powered by the Debug USB Socket, the Micro-USB will only output ca. 4.3V which is not enough for the GM5
Solution: plug a 5V PSU to J2 of the MBHP_CORE_STM32F4 module, and let the USB PWR jumper J17 stuffed:
All 5 MIDI IOs of the GM5 are recognized, and can be used for MIDI message processing.
Best Regards, Thorsten.
Hi, when I connect my GM5 I can only see and use 4 MIDI IO's
USB1-4
How can I find and use the 5th?
I run 0.88

If you have a spare AOUT_NG finished module, kit or PCB, I would like to buy it.
Cheers, Hal

Thanks guys :)
The last part is filmed with a device I built with an Arduino and a servo motor, so the camera pans clockwise in the same speed, so I could sync it to the overlayed footage. Yes, it's mounted on top of my car. Some people get dizzy and sick watching it :)

I have a new tune & video out.
Sounds are from my MBFM.
This time I have released it on VHS cassette http://www.tigernet.no/item/150179--prinztronix--pressing-buttons-vhs-video-single--merchandise
For those that don't own a VHS player, it's available on streaming and download too ;)

Great video. Very informative. Thank you.
I must say all your work is outstanding. Those FM-machines are really mind blowing.
Cheers

Hi.
I'm not an expert on this, but I did read up on this the other day.
SD cards are optimized for image and video, and the newer and faster cards cause problems for other types of usage. Try to get a class 4 card.
My 2 Cents anyway :)
Sorry, didn't see first that you already have class 4 cards

Now I have my MBCV V2 connected to my SEQ V4 (STM32F4) with a USB cable in Host Mode. The MBCV V2 is powered through the SEQ.
The SEQ crashes sometimes, and I suspect that is has to do with this connection.
My question is:
-Will the MBCV V2 work the same if it is connected to the SEQ with a normal MIDI cable? Will it be "slower" than the USB connection?
I only use the MBCV V2 with an AOUT to control 2 filters from the SEQ. Would it be better to connect the AOUT directly to the SEQ?
Cheers
Hal

OK. I have reverted back, and it works fine like before.
I wanted to add some gate triggers, so I guess I have to add them before the TPD then, or can anyone suggest an easier/better way to add 8 gate triggers?
-
Thanks for the tip TK.
I don't understand the behavior because I have used it for a while with the TPD connected after the BLM, and it's worked fine.
The only reason I changed it was because I saw that I could get a shorter cable if I connected them in the reverse order.
My hardware looks like this
On Wilba's frontpanel the DIN/DOUT connectors are on the left side.
On the TPD they are next to each other, but on the BLM the IN is on the left side and the OUT is on the right.
It made sense to me to keep the cable stretches as short as possible, so I tried Core -> Frontpanel -> TPD -> BLM with the attached config file, but I ran in to the problems mentioned.
I guess I should follow the "If it ain't broke, don't fix it" rule.
I'll just revert back, shut up and make some music ;)

Hi,
I have changed the order of these in the DIN/DOUT chain.
I now have the TPD first then the BLM
I have edited the MBSEQ_HW file, but there is something wrong.
The 4 LED's on the TPD are constantly on, and the BLM acts strange
Could someone please check the attached file, and see if they can see something wrong
Cheers:)

Great work. Looks sweet. Love those buttons. Thanks for posting the pictures,

I have SEQ V4 (STM32F4) with ilmenators BLM 16x4 and TPD.
I want to add a DOUT Shift Register for gates.
Should I connect this SR at the end of the chain, after the TPD?
How should I write this in the config file MBSEQ_HW.V4 ?
If Wilbas CS uses 2, the BLM 9 and the TPD 6, is SR 17 correct?
If this is the place in the config file, what does "Allowed values: 1-16" mean?
################################################## # CV and Gate/Trigger/Sync Setup ################################################## # AOUT interface now selected in CV Configuration Menu and stored in MBSEQ_CV.V4 file # please scroll through the menu to find this page! # additional gate triggers are available on common digital output pins of the # DOUT shift register chain - they are assigned to AOUT channel #16 (Note C-1, C#1, D-1, ...) # define the shift registers which should be used here (each provides 8 gates) # Note that SRs assigned to this function cannot be used as LED outputs (exclusive function) # Allowed values: 1-16, 0 disables the function, all other values invalid and not allowed DOUT_GATE_SR1 0 DOUT_GATE_SR2 0 DOUT_GATE_SR3 0 DOUT_GATE_SR4 0 DOUT_GATE_SR5 0 DOUT_GATE_SR6 0 DOUT_GATE_SR7 0 DOUT_GATE_SR8 0 # if set to 1, the DOUT "gates" will send 1mS pulses # useful for analog drums DOUT_1MS_TRIGGER 0

Sounds great to me. I'm looking forward to this new Mb project.
Very impressive work, as always.

The Gallery behaves very strange for me both in Chrome and Firefox
Thumbnails don't show, and the images don't show when you click on them
Also the Members Gallery comes up in reverse order?

I just filled out the "G-form".
I'll wait to see it you will offer a kit. I like kits but not completed modules "Are you kidding? This is DIY! My soldering iron is smokin'!" :)
After seeing what you have done with the MBFM on STM32F4, I'm very exited about this.
If you're after a new project after this, could I suggest the NES RP2A03/RP2A07.
I have a MIDINES with a MIDIbox 64 CS, but I would love a full MIDIbox one.

This is so cool. I used to have a SEGA Mega Drive (EU version of the Genesis) with a GENMDM cart and midi interface from Little Scale. I loved the sound, but not the UI. I am interested in yours, but what is the availability of the chips?

I would like to have two clock outputs from my SEQ V4 to sync two delay/echo effect pedals to the sequencer.
The effect pedals have a tap tempo, and I wonder if anybody think/know if this is possible.
If I understand correctly the STM32F4 core can have 8 clock outputs.
Are these suitable for this purpose?
Is it just a normal DOUT circuit?

Hi casius,
Yes that one will work, mine has a "weird" package
Do as you suggest:
>remove bc337 & resistors, add bridge
>remove P1 (LUMI) 10k trim pot,
I cut the third leg on the new trimmer, and mounted the two others to Ground and the bridge to B-
Before you connect the LCD's, measure the new trimmer, and set it to 2-3K so you can slowly increase the power
The LCD's are connected in series with one flat-cable to J15B, because in my case I could use a shorter cable if it went to display 2 first.
I cut the wire from E after the connector to the closest display, and ran a separate wire to E from the other, to E on J15A.
Hope that explains it :)

well, to be accurate
be sure to use the files for pic18f4685 ;)

I have tried one of these adapter cable and it powers my SEQ directly from the USB port on my Macbook Pro, no powered hub is needed.
It all depends on how much current the USB port your connector it to can provide.
yes, that is true, some USB 3.0 ports deliver 900mA, which could be enough
the standard usb 2.0 port delivers 500mA, which is not enough for a SEQ V4, but it also depends on the CS, LED's, LCD's etc.

I think one button should be a preset for the "Magic BPM" ;)
