ultra

hello! this is a group buy for the pcb i recently made called the ultracore. http://midibox.org/dokuwiki/ucoregb it's a core, 4 IIC modules, and 8 banksticks on a single board for midibox seq, router, and other uses. board measures 160 x 80 mm there are two lcd headers and they match 1:1 with many lcd pinouts (i.e. nebula's optrex 2x40) $16 + shipping and i will take payments through paypal.

hi, does anybody have some white on black "waldorf" knobs laying around? i need 8 of them for a simple knob box project. i'll buy, or i can trade some gray on black waldorf knobs. thanks, ultra

i swear i read your post but missed the part about it syncing when the bpm is set to 0. i'm gonna build this as-is :D i can live with just sequencing cc's from the mb-seq and delaying notes from the magic midi delay. in fact, i wouldn't exactly call it "live with", this is gonna be awesome. :)

can't have too many kinds of sequencing

well i finally sorted out all the mackie vs regular old midi stuff and have "finalized" a panel layout. it's more heavily based on mackie control now. perhaps it's a little higher on the skill/feature ratio now as well :P. i dug into the mackie protocol and tested out each feature to see what i would actually use, and it turns out there's enough control i'd like to have to justify removing the touchpad mouse. there wasn't really room left for it anyway. i'm going to make a 2 core pcb with tk's usb chip on it, allowing me a mackie input as well as a general midi input.

me too, the test batch were shipped today!

I used mouser part numbers in that list, but you can get mfg part numbers from mouser's site. the parts used for the core are exactly the same as the list on smash's site. for the iic modules, the difference is you won't need the 10uf caps. also some of the headers are obviously different.

if someone feels like making boms for other suppliers they should feel free to send it to me and i'll put it on the wiki. I personally don't have the time or ambition to do it, and I don't particularly care for dk anyway since they've failed to follow simple shipping instructions in the past.

no read up. i haven't even started accepting orders yet and any mentioned in this thread are not going to be counted. just watch this thread and i'll give group buy instructions. then you can be counted :).

hey nebula, my payment was processed on monday and i haven't received word yet about when they'll be completed and shipped. their website says 4-7 days return, so by next week i should have the pcbs. do you order from mouser? here's a parts list for them. this will go into the wiki soon but i have to verify it's correct. i did the best i could but sometimes you just don't know until you're soldering everything together. it won't be off by any major components.

this wouldn't be too hard of an app to recreate as long as i can figure out timing. i like the idea of this, especially delaying/repeating control changes. however, how do you recommend it behaves, dcer? it could take a cc at any moment and repeat it a set time later, but would it return the parameter to the starting value, or stay put? how would you determine what is starting value? what do you think dcer10? could you give me a description of how delaying cc's could look?

thanks wilba. sounds like the best solution for me then.

my setup for my live controller is going to use two cores, and i've been playing around with the best way to get them to share information back and forth. connecting MI to MO and MO to MI doesn't seem to work, because i get black bars on the screen... there's probably midi feedback or something. using CAN is a bit beyond me and it's probably too big of a solution for my application. so i'm wondering it's possible to simply have one switch go to shift register inputs on two din modules, each din module going to a different core. perhaps using diodes to keep them from interfering? or would they not interfere at all? the only information i need to share is basically keypresses (layer and channel select buttons) so any kind of actual data communication isn't really necessary. i'm going to try this idea anyway, but even if it works i'm wondering if there are some downfalls i should look out for. thanks, ultra edit: btw both cores will be on the same pcb and will share the same vss path.

you got me thinking about this: get into the delay menu, select which track you want to edit directly with the corresponding. track select button. the three main delay parameters for each of the four delays shows up on the lcd above the encoders. this would take 12 of the 16 spaces available on that immediate screen. space 13 could have a space, and space 14-16 could have the option to include layer a, b, or c in the delay! is anybody at all interested in lifting the mmd code and adding a menu to the seq? unfortunately when i look at asm code my head spins.

4 channels... 4 delays... :) if i knew a thing about assembly or assembler or whatever it's called, i'd give it a try. this is a good reason to leave F1-F4 buttons on the seq. who knows, maybe i'll be able to do it in the future :).

i'm juuuuuuuuuust getting into mios programming and c in general so it won't be me :). although i will be writing a full app soon for my ableton live control surface, and i also want to make a "midibox klee" that programs more like a mb-seq. does this magic midi delay send control change delays by default? or is it just notes? edit: basically what i would like to see is that the mmd just repeats whatever is fed into it.

can this be synced externally? i made a 1u layout for this. the holes for the encoders are not drill-size, it's the base size of the "waldorf" knobs. so there will be much more space between them at the top of the knob. :)

you'll have to provide a link to the actual lcd or the datasheet.

i originally was only going to make this pcb according to what i need, but after some time talking to others i realized it wouldn't take a lot more effort (actually, it did :P) to make it more useful to others. so now it's set up for anybody building a seq or midi router, so it includes all headers you'd find on the core. i ordered the first batch of pcbs last night. as soon as i can verify everything works correctly, i'll open the group buy.

thanks. it'll be soon!

thanks dcer10. this project is definitely still on my (long) to-do list. thanks for the pics and demos. i keep thinking i could combine it in the same box with some other kind of useful midi processor. or a 1u rack. would be great with a midibox seq and a klee.

thanks. i'm so new to c that i'm probably not going to bother with it. although this information is probably useful to anybody searching on this :). i got mblink to work right and it should serve my purposes.

hi, watch this thread for the group buy and that's when i'll get an official count. i'm not keeping count of who wants what at this time. oh and please be patient! i'm really broke right now but soon i'll be able to get this started. i don't want to do a pcb run until i have a working, fully loaded pcb in front of me. ultra

the smt soldering should be the last reason anybody avoids this order! it's really not hard at all. I did some this year in school and all it took was some patience and a flux pen. I actually preferred a screwdriver tip because I could solder a few pins at a time. thanks for this group buy tk. it showed up at just the right time.
