oh... duh. man how did I miss that.... sorry :whistle:

Is this possible, or do I need to get another AINSER64 board? I'm building a keyboard controller. I have 1 AINSER64 with all the 64 inputs being used, can I chain a kb module to it? In other words, can I simply connect the J1 output from a kb module to the J2 input on my AINSER64 board?

Maybe I read something wrong (or I'm just ignorant)... but the confusion to me is that the MB-KB appears to have a plan for functionality that overlaps the MB-NG quite a bit. So for people who just want a custom keyboard controller with a fist full of knobs and buttons, what are the limitations in the MB-KB (assuming a future ver. supports 128 pots + a bunch of DIN/DOUTs), that would necessitate building a MB-NG to go with it? Is it just fewer DIN/DOUT's, or something else? Either way I'm stoked that the MB-NG is out soon! The news has finally got me off my ass to drill my panel. This will be the best Christmas present :) Thanks TK!

Core is now working. Newhaven RGB display:

Yeah, the post and knobs are the most exp.( I've got 100 pots/encoders + a ribbon controller). I've been wanting a better master controller forever... :)

:whistle: oops... found my dumbass problem. all good, sorry for the post!

Okay so my core isn't being recognized by MIOS Studio (or anything else). LED flashes, looks like it boots etc. but it won't come up. Bad flash? I have the LPC Link separated. Since it's on headers, I went ahead and tried to flash it again, but now it's showing up as "Ed:02: Failed on connect: Ee(92). Unknown error" in the IDE for OSX. On windows, still can't flash, but I get "02: Failed on connect: Ep(01). Target marked as not debuggable." instead. I tried booting into the ISP bootloader (GND the ISP pin, #51->#54) no go, even with flashmagic over ethernet (can't communicate). Any ideas?

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.

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.

Got a whole big box of parts from SmashTV! Finished all the modules except for the core, which I'm working on now. It's going together fast; I must say these PCB's are very nicely done...

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?

Thx! Here's hoping I don't fry something...

Finally got off my ass and ordered all the electronics to make this puppy happen. :sorcerer: Making a fully stuffed midibox64e. Going to try with the LPC17 core, so I don't even know if I'll be able to getting working until TK releases the NG stuff for it. Anywho is what I'm trying to make. Going with regular LED's per Hawkeyes rec. and I'll wait on knobs and make a dummy layout to see if the spacing is too tight per ilmenator's and Tbreath's concerns... Total damage so far: $160 from mouser + $258 AVI Showtech = $418

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!

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.

:) ...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:

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?

Just about to place an order, and I was hoping someone with some exp. could do a once over to see if I've forgotten anything, or misunderstood the specs. It's a relatively full stuffed Midibox64E: 64 Pots, 40 Encoders, 48 buttons, 40 LED's, 8 LED rings. Thanks!

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: http://www.doepfer.de/presse/A100_Monster_04.jpg Thanks!!!

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.
