Perhaps you mean the ethernet port is flush with the surface and the MIDI & USB are recessed (i.e. back the depth of the panel)? Basically I want the UTP port looking kinda like this:
Put another way, I guess what I wasn't sure of is if it's okay to have the other ports back 0.1" (i.e. behind the panel front as opposed to flush with the face). Looking at my other midi gear the MIDI ports are recessed, but the USB is flush.
-
I have a 0.1" aluminum sheet I was hoping to cut and get a nice clean panel on the back for all the connections. Everything looks like it'll be flush, except the magjack, which sticks out. What have other people done to get this to look nice? I was thinking to just attach the magjack with wire a few mm off the board so I could push it back, then just JB weld (glue) it in my panel. Stupid idea?

Depends on how accurately you want to model it. Massive's knobs within knobs with max min settings, is going to be near impossible to capture like the layout. Also, Massives LFO curve selector/editor would be a pain. One more thing,a single old core (the new core isn't supported yet), is going to be limited to around 100 knobs/faders and 50 buttons. A single core controller, fully stuffed, is going to run you around $500, and you'd still need to cut and paint your panel.
If you can work with that, you can have a bad ass controller for Massive, that mostly captures what you want. You'de still need a mouse to do a few things, but overall your controller would make tweaking a whole lot more accesible. I'm also really interested in a controller for this synth, so if you do decide to build it I'd love to see what you come up with. Good luck!

Looking nice...
What works good for me are Reichelt 10mm knobs - good grip and also possible to get your fingers between them in tight spaces.
Also, maybe rethink the use of white 1200mcd leds, even if they are "pulsed" as in led-matrix connected, they will be probably bad to your eyes after some time (green, yellow or red is best for long usage).
It is like supermodels, sweet to look at, but when you have to work with them, annoying after a few minutes :-).
Also, if you have the time, wait for TKs new LPC17 based solution, it will be <put 10 pages of hymn text here> ;-).

Good point... even blue seems too intense to look at long. Funny how LEDs have gotten almost too efficient/bright. I was even thinking to build out a PWM driver module with an interface for the DOUT board, just to bring the brightness down. Perhaps I'll just do red or amber and save the effort (and my eyes).
Yeah, I'm digging the new core. I've pretty much settled on buying the components and hoping that by the time I get it all wired up, the AINSER64 boards will be available from SmashTV.
-
Looking at the frontpanel I would suggest that the encoders and pots are too close to each other. It will be a problem to change values without accidentally touching neighboring encoders/pots. Unless you are using a pair of tweezers to grab them...
:)
...Yeah, it's tight. The columns are a tad taller than eurorack height though, and the minimal spacing (assuming 15mm diameter knobs) between knobs at the base should be at least equal to what you'd find on Doepfer's A-100 analog synth modules:

MB64E doesn't run on LPCXPRESSO, only on the old PIC based core.
For MIOS32 MBNG will provide equivalent features (+ more), but this application isn't available yet.
However, if you are planning to implement the app by yourself anyhow: the tutorials are here: http://www.ucapps.de/mios32_c.html
Another discrepancy: for LPCXPRESSO you will need a AINSER64 module, MBHP_AINs are not recommended.
Best Regards, Thorsten.
Thanks TK!
So I have a workable solution if I just drop:
1x LPCXpresso: LPC1769 LPCXpresso board
1x #77 Core LPC17 Module PCB w/MagJack
1x #78 Core LPC17 Parts Kit
And then add:
1x #02 Core8 Kit + PCB (PIC18F4685, Panel MIDI Jacks)
...or I swap out the AIN's for AINSER64 and either code the app, or wait for MIOS32 MBNG. Yes?

I've been putting off building a 64E box for too long. Now that I'm committed to it, I was hoping that someone could advise me as to how much I can add on a single core these days. With a LPC17 based core, can I add more I/O? Or am I still limited to 64/128 encoders/buttons? My 'minimal' setup (so far) consists of:
64 x encoders
64 x pots
64 x buttons
768 x LED's (11 for each enc. + 1 for each btn.)
1 x 2 line LCD (at least)
My optimal setup would be almost double this.
I also want a keyboard with aftertouch and velocity sensitivity. Unless I'm mistaken, I don't think I can have this on the box, but it would be nice (I have an old novation controller I want to cannibalize). Some icing on the top would be to have a 16 char (over 2 lines) lcd for each encoder and pot (or a couple of really long 2 line lcd's) for labels like on the novation SL MkII.
Basically I am trying to make a hardware controller that mimics the immediacy and detail you'd find on a traditional modular analogue synth:

30K goes into 1M 33 times.
So, 33 1M pots @ $2 each would cost $66.
$20 sounds like a bargain!
Hmmm... yes... I hadn't pondered that. Maybe I should look for 1T pots, that way when archaeologists unearth it from my great-grand-kids grave, I'll rest easy knowing it'll still rock out. :)
I guess I'll settle for 100k. I'm betting my old Roland pots that died were at best 30k and those lasted almost 5 years. Though, yeah, not sure about the feel.
I'm thinking the Bourns PEC16's, they're still relatively cheap, and they go to 100k. But the running torque is about half that of the Alps everyone else seems to use though, it might be too loose, like a jog wheel. I'll have to see if I can test drive one.
-
Should I go ahead and get the PIC based core from SmashTV, or hold out for the STM32 core? I plan on maxing out the core's DI's and AI's, and I also want to add USB.
Also what's a good lifetime for pots/encoders (I'm building a VI controller)? I've burned out a few on new synths in less than 5 years with heavy playing. 30k rotations seems awfully low, but the 1M encoders I found are like $20+ a piece!
-
Ah yes, I see, thanks for the clarification! So, you only get 8 additional DI's if you don't use the AI's. Makes sense.
Well cool, it sounds like I can do it on a single core then! Not that I'd mind an extra core, but I'd probably layout things differently if I had to use two.
Thanks for the info! :)
Now to put together the parts list...
-
Thanks guys!
From the 'progress' portion here http://www.ucapps.de/midibox16e.html, I gather this is what's possible:
up to 64 rotary encoders
up to 64 buttons
optionally up to 64 pots or up to 8 motorfaders
On that same page, under 'How many Rotary Encoders should I use?'
'A later version of the application will provide 8 additional inputs at port J5 of the core module for connecting 8 buttons'
---------------
Assuming I've read this right, you can have 128 DI's (with each RE counting as 2 inputs), possibly 8 additional DI's, and 64 AI's. I've optimized my layout a bit to include:
64 Knobs
41 RE
43 Buttons
which includes 8 buttons to handle menu navigation and special functions. Again, if I read this right, all of this should fit on one core.

Just wanted to make sure before I buy a bunch of components... I'm making a mega knob machine with a keyboard with after touch (cannibalized from a Novation controller) to control a VI :P
But I'm a little unclear just how many analog knobs, rotary encoders/buttons, I can have. What is the max anyway?
I've parred down the number of knobs/controls to this:
73 Analog Knobs
46 Rotary Encoders
27 Buttons
Keyboard with aftertouch
I'm assuming I need 8 buttons to modify patches for the 64e, otherwise I'd only need 19 buttons. Actually I'd like to have 119 Rotary Encoders, but am I reading the specs correctly that I can 'only' have:
64 Analog Knobs
64 Rotary Encoders (actually, I guess that I have a max of 60 Rotary Encoders + the 8 Buttons needed to program the MIDIBox).
I realize that I can just make a couple of patches and cycle thru them as needed, but I have an insane desire for more knobs :)
Thanks!
Led Encoder Ring PCB
in MIDIbox HUIs
Posted
Mayhewlabs is way too expensive, It'd be cheaper to buy a Behringer BCR2000 and rip out the encoders + rings from that (plus you'd get a bunch of other components you could use)...
I would totally love a LED ring PCB. I'm about to wire a bunch of loose LED's into ~100 holes I've yet to drill. PITA. What I'm really interested in is LED ring + PWM interface, then you can use superbright LED's and use a single pot to adjust brightness on the fly. What I'm not sure about is using a ring with SMD LED's and how to mount that to a panel.
