FWIW I recently finished a sammichFM that followed Siempre's color scheme. I tried 3 different LEDs using the stock 220 resistor. One (Mouser 604-W934MBDK) had 25 mcd brightness and was perfect (I don't like super-bright LEDs). The other two were 700 mcd (Mouser 593-VAOL-3LSBY1) and 190 mcd (Mouser 859-LTL1CHCBK - end of life part so not recommended). The latter two were much too bright so I tried Siempre's painted-LED trick and it worked great. I just dipped each one right into the paint about 3-4 mm. The brightness was good with a single coat. In the end I went with the un-painted version since is was the most straightforward and I was worried the paint would make the LED too big for the hole.
So now the important question: do I still get to call my color scheme (arctic white case + blue LCD/LED) the "Siempre de la Luna Edition" without painted LEDs? :-)

Here's what I was thinking on a rear panel design (see image). It doesn't have an ETH port, but that could obviously be added. I don't like having the MIDI ports split into two groups as on the other case, hence the need for panel mount MIDI jacks. Panel mount for everything gives more flexibility for layout as well. I agree the other case requires some strange use of spacers and such, so again, panel mount to the rescue. I couldn't find a panel-mount SD card, but I think some small L-brackets would do the trick, along with some spacers on the rear (IIRC that was discussed in the thread for the other case).
It has an IEC power plug + fuse so I could generate the +/- required for the AOUT_NG. I have samples of the parts that I measured for doing this layout and can supply part numbers if anyone is interested. I also have an SVG of the attached image if anyone wants it.
My idea for the top flat part (see image) was to do 8 trigger and CV outs, and have stereo audio in/out through an SSM filter. The necessary filter CV signals (2 x cutoff and resonance) would be shared with 4 of the CV outs and controlled via the filter enable/bypass switch (would need relays or a many pole switch to make this work I think). I've not tried it, but it seems the MB-SEQ should be able to sequence the filter which might be fun. And besides, that space just *begs* for something!
All your discussion on this case has gotten me back thinking about building my MB-SEQ...
Thx,

That's a great idea to have Hammond do it since they can do all the machining before the panel is folded.
Another good thing is there is plenty of space for an on-board power supply (including center-tapped transformer for doing +/- supplies), 4xIIC MIDI modules, AOUT_NG, etc.
What would you have Hammond do for the rear? The design I was working on a while back included a DB-25 "expansion port" like on the MB-6582 for future expansion. When I get home I'll see if I can dig out any of my drawings I started a while back on my plans for this case. To fit as much as possible on the rear panel I found some panel-mount USB extender cables, and I was going to use panel-mount MIDI jacks as well.
I'm sort of torn on the LEDs. I want to solder it all up and try out the SEQ with the AOUT_NG and an SSM filter module to (1) see if I can get it all working and (2) see if I like it before doing custom machining / whatever with a front panel.
Did you use standard 10mm spacers? The LEDs in your pic look a little low to me but it might just be the pic. I suppose I can probably just measure my MB-6582 LED height and shoot for the same height (plus/minus any delta for the difference in panel thickness) and then use spacers to get the LED height consistent.
Also, can you post a pic of your MB-808? Curious how it came out re: your above comments.
Sorry for all the questions!
Thx,
C

If I'm not mistaken I have that exact same case. I was planning on getting FPE to machine it when the other case option came up so I was planning on getting in on that instead since I like the form factor better.
My plan on the flat part on top was to put gate and CV outs, and/or maybe an audio in/out to sequence an SSM filter module.
Are you not a fan of engraving, or was it just too expensive?
At any rate I'm interested (path of least resistance!). Keep us posted and let me know if you need help running anything.
Oh, one more thing- how did you set the height of your LEDs consistently w/out a case?
Thx,

Crikey! I slack for a few months and come back and Wilba's gone and designed a whole new project. Beautiful job as always!

Not 100% but a helpful list for the MB-6582 CS:

+1 for me.
Thanks,

TK,
How did you solve the issue of spacers on the other boards that go to the rear panel? As you noted the CORE32 has the spacers moved back due to the USB jack, but the other boards do not have that. I have been considering how to do this on another case and was planning to use panel-mount MIDI jacks (those nice shiny ones that Bugfight likes) and a panel-mounted USB cable extender (http://www.cablestogo.com/product.asp?cat_id=1532&sku=28070). But I still have a problem with the SD card mounting holes (pity I have not been able to find a panel-mounted SD card jack). I was thinking I would use two small L brackets to connect the board to the rear panel, but I'm open to better ideas...
BTW It looks like from this picture (http://midibox.org/forums/index.php?app=gallery&module=images§ion=viewimage&img=427) that the connectors on the corners can rotate to change the angle of the case depending on how tall the rear panel is. Very clever. In this same picture you can also see the 1mm extrusion on the back panel holding it in place.
Thanks,
C

My boards arrived today, thanks!
No worries on delays. Having run a couple of bulk orders I know how much time it takes!

Yes, but which side has the connector, where are the mounting holes, etc. :-)
Whenever you get to it, thanks!

Seppoman,
Can you provide the dimensions on the SDCARD module in the current bulk order? I may want to use it in my MB-SEQ design so it would be helpful to see the board size, layout, etc. for planning purposes.
Figured I'd post my question here instead of PM in case others are interested.
Looking forward to the bulk order!
Thanks,
C

Hi Altitude,
It looks nice but with a LCD this flat case is not optimal.
I would prefer a sloped enclosure (Pultgehäuse) or a keyboard enclosure, see Link.
Best Regards
Jack
These look like nice enclosures. Has anyone ordered from them?

1000 congratulations for this great community,
TK, Wilba, Fussylizard, and much more...
Don't give me that much credit. I just shipped a few packages so Wilba could focus on sammichSID. :-)
I'm out of PCBs from the January order, so people wanting MB-SEQ boards should add their names to the bulk order page like you did.
Regards,
C

If you're into dance stuff get some of the Vengeance Sound sample CDs. Airwave Triloops is pretty good also.
I'm getting better at programming dance drum loops. Still have a ways to go. The Jomox 888 helps a bit since you get a nice, full sound with little processing (though a little pumping compression helps). You need a little swing as well. And just start adding in quiet little accents here and there as well as some toms or little clicks or bleeps. I often will add in a loop for a shaker or extra hats or something which helps. I made a pretty good loop the other night using Tattoo and some other little bits and I'm still not 100% sure how I got there, but the main gist is practice, practice, practice...
Hopefully I won't have to work this weekend and I can get in some music time!

Grizz just PM'ed me about parts from SmashTV so you can add to the above Mouser list the following from SmashTV's shop:
- 1 x base PCB
- 1 x base parts kit
- 1 x control surface PCB
- 1 x 2 pin header for the fan
- 8 x 8 pin headers for the CS to Base PCB if you use right-angle headers like I did (highly recommended)
- 1 x 2 pin header for the CS to Base PCB if you use right-angle headers like I did (highly recommended)
- 1 x 16 pin header (2x8) for the LCD
- Ribbon cable for LCD and base PCB to CS (I would get 4 feet or so)
- 8 x 3 pin headers for the feedback pots
- 1 x 2 pin header for the mini phono ("complete mix") jack
- 1 x 2 pin header for the power LED on the back panel
If anyone notices anything missing please let me know and I'll amend this post.
Thx,
C

Not enough drum loops??! Time to hit the sample CD stores. :-) Though these days I usually roll my own from individual hits, with the occasional hi hat loop or something. That works great for dance-y stuff that I like.
I also recently got Audio Damage's new drum synth Tattoo which is loads of fun, and I just got it outputting MIDI to my 888. Good times ahead on the drum front!

Just gave it a listen and I like it, esp. the percussion, the melody starting around 1:45 (SID I'm assuming?), and the arp starting around 3:15. I need to knock out a few songs myself, it's been too long w/ work, bulk orders, MB-SEQ, etc.
BTW I just got Ableton myself. It won't replace my beloved FL Studio but I was so jealous of baconjuice's monome in our last jam session that I got a Launchpad, and ended up getting Live to go w/ it. If you get Max 4 Live + a Launchpad you can get Novation's sequencer app that totally rocks. I'd love to tweak it to work w/ the MB-6582 bassline sequencer (may have to hack in some firmware changes so I can control steps from MIDI), but time is limited. Darn that irritating little thing called work...
Anyway, nice work and thx for sharing!

Not sure where you are located but here's a post with a list of Mouser part numbers that you might find helpful:
(I really need to add this info to the wiki...)
You will also need some bolts, nuts, etc. I assume you've seen the wiki page for the project which has all the info:
http://www.midibox.org/dokuwiki/doku.php?id=wilba
There is a parts page that should answer most questions.
The PCBs are well labeled so it is a relatively easy build. Just go in stages as directed in the build guide and actually do the tests at each step. Trust me, this will make your life much easier. And don't insert your SIDs until everything else is solid. You don't want to risk frying those not-so-easily-replaced parts.
Have fun and post questions if you get stuck.
Regards,

Building A SEQV4 with a bunch of Midi outs (Via IIC>Midi) and CV outs (Via AOUT_NG)
FYI I'm doing the same w/ my MB-SEQ. I'm (slowly) working on a case design for this as well based on an off-the-shelf Hammond case (http://www.hammondmfg.com/pdf/1456RH3.pdf). I'll let you know if I come across anything interesting in my build. I also plan to have an internal power supply for both the MB-SEQ and the AOUT_NG based on the design used in the MB-808.
-
Do you get MIDI from the first core? I would pull out all chips (SIDs, control surface ICs, etc.) except for the first core and check the MIDI I/O using MIOS Studio.
If you have a standalone, known-working core PCB you can test the LCD there to ensure everything it is wired correctly, etc.
Did you use headers to connect the base PCB to the CS PCB? If so, I would focus on the base board first, then when everything looks good there add in the CS PCB.
-
That sounds like it would work on the MB-6582 side. I'd have to check the schematic to be sure, but it should be OK.
One problem you might run into is with your bipolar PSU. I'm no expert, but I've read that some bipolar power supply designs do not work well when you try to pull more current off the positive supply than the negative supply. I use a Paia +/- 12V power supply for MB-FM. I tried pulling +5V off the +12V side and it didn't work correctly. May have been user error, etc. The Paia supply also uses a voltage doubler circuit which could have been a problem.
You'll probably just have to try it and see if your supply works, doesn't get too hot, etc.

happy new year to all,
iam new here and just ordered the core 32 and other stuff to build the new seq v. 4.
i`ve seen that there was a bulkorder from wilba for the pcb behind the frontpanel, but i think its close or?
i´am very interested in these, are they still available?
can anyone tell me were i can order it?
thanks very much, greatings:-)
There is a small (closed) bulk order going on now for the "bleeding edge prototypers". What this means is (a) you have to figure out your own case solution, and (b) you have limited build instructions, help, debugging info, etc. This bulk order is already closed, but if there are any spare boards I will post about it here once I devise the most unfair system possible for allocating spares, if any. :-)
Once there is a full bulk order getting started, Wilba or someone will post here about it.
Regards,
C

I'm running Wilba's "Bleeding edge prototypers bulk order #2". If Wilba has confirmed your order you should have received an email from me on Dec. 22 explaining what you need to do. If you have a confirmed order from Wilba but have *not* received an email from me, please send me a message via the forum so I can ensure I get your order details. If I don't hear from you by Sunday, Jan. 10, I will assume you are no longer interested and will allocate your board to another buyer.
BTW I believe all PCBs have been allocated to buyers at this time. If any spares become available, I'll post here and see if anyone is interested. :-)
Thanks,
C
sammichFM behaving oddly **FIXED**

Damn! So close, so close...
BTW Did you get the blue Optrex recommended by Wilba (C-51505NFQJ-LB-AJN)? Mine is a little dimmer than I would like. The backlight pot has zero effect both with and without JR4A. Contrast is set to max (or is it min?). So does the backlight pot do anything on yours?
Thx,
