AhAh time to put this website online! Hihi @Hawkeye I love the new banner of the LoopA page!!! You put style in it I like that!

mnmlCore for minimal maybe, I don't know like you want ;) The perfect thing could be to get the exact same ports as the Core8, with a smaller package of the stm32f407on a DIP-40 formatted board. => this will allow to upgrade all old midiboxes easily, increase processes and speed of @latigid on 's BLM for example... => we've got it for other new tiny application. Just an idea, but it's maybe impossible to get the exact same pinout and everything on a DIP40 board, don't know...

@Phatline Yes a small and generic board could be a great thing, I'm always tempted to use the LPC for its size but I need the STM features for some applications :/ This must be a clever alternative to the wCore, not a concurrent but an answer where the wCore can't fit our design. There's a lot of way to think about it, we can maybe start a new tread and begin to discuss about it...
-
You're welcome! Your "v1.0 wCore boards" have already allowed me to do a lot of things, it's up to me to thank you! I will refresh the devPlate design once the shop is open ;) Ahahh micromatch type, good choice here! This two boards deserved a strong and durable link cable Great! :)

Great video! Good Job!
-
Genial! It will help a lot! More than the Seq parts which are used here, this video contains a lot of tips and tricks! Great!

Hi, Finally?.. What is the features of this board? Which legacy ports are available? What is the size of the board? For which purpose did you think it for? Did you make some specific changes in the MIOS32? Did you adapt it properly? I'm opinion is that it should be fine to get the same features/ports/possibilities as the Core8 but with a core32... Could we help you to improve it? @FantomXR Your soldering of the stm seems clean, perfect on the picture... I will be interested in an oven soldering, can you provide this service to people here? For prototyping or small series. Best Bruno

You can find inspiration from the BLM Modules in the SVN. With an STM32F4 core: SRIO with Default MIOS32_PRESCALER_128, a scanline will take 36us. 84/128=0,656Mhz => SPI clock period is 1,52uS Your total scan line is: 1,52 * 24 = 36,57 us For you to know that the SRIO scan a line every ms, then your total scan will take 21ms For better accurate you can write your own module to scan all lines within the 1ms period: 36,57* 21 = 768uS If the remaining time for other processes is not enough(here 1000-768=232us) and your circuit permits it, you can decrease the prescaler to 64, total scan will be 384us... Try to debounce in circuit too ;) What I told you is just some track to explore! it's not a ready-made truth ;) Prototype it and code it before pcb design! ;) Have fun Bruno

And if you want the 2 layer switch. try to use 24 DIN lines with 21 DOUT scanlines, maybe with even DIN lines connected on top and odd on bottom switches as you can apply some mask in the software and calculate the duration easily, Anyway keep the 2 layers on the same scanline, easy addressing will help you to compare the timestamp pairs. Just an idea.

Mignon! -
So you do not care what section you hit. Why? that's a shame cause the SRIO is able to handle it even if you've got 2 switches layers and with not too much latency. it's 3 registers out x 3 registers in. The scanning order of your buttons is important as you can measure correctly the duration between 2 associated Switches. But maybe i'm wrong, @Phatline? @latigid on is an expert in switches matrix and BLM, ask him maybe!

Hi, Did you know that there's here more than this link? I found some thread about it. LVL1 is @TAG here ;) I just typed "isomorphic" in the search and there's a lot of topics with some different approach like wilba's one, that can maybe help you, don't know. Same as @Phatline I can maybe help you but you have to explain more cause(maybe it's just me) I don't understand which line you want to duplicate, for me duplicating the lines will not reduce your SRIO scanning except if you duplicate the SRIO itself... and MIDI channel part assignment is another thing(comes after).

If it works fine you will never ask yourself this question again ;) hihi
-
I'm working on it right now! I spent all my free time on this ;)
-
He pointed it out to me too
-
Done! I return to you and Peter once I've got an answer ;)
-
You maybe busy, you want me to try, take the first contact? There's a lot of new models I just order 2 more: Syncussion and SH-9 :)

Above ;)

About the dust... I've got beautiful dust cover for my 909 and 727 which come from stardust in Portugal, made in Portugal they are able to fab various shape. https://www.stardustcovers.com/store We can maybe deal something with them and put it in the shop ;)

If you mean counterbore(chambering) not sure he will be able to do it because of the panel thickness. About the other famous sequencer like, I don't know how it's made but I've got a MPC X and there's a plastic panel under the front panel You will get the same problem with the switches, isn't it? Then... With a bigger cut-out, the problem is that only one knob diameter will fit inside, so no customisation ;) I think about this (thin encoder) diameter is 14.2mm, https://store.djtechtools.com/products/chroma-caps-knobs-and-faders Insert other media Have a good afternoon!

This is weird cause it's a ground plane on the bottom side! You can also scratch the silkscreen a bit, stretch the solder a little and connect to ground plane.
-
You maybe change it after testing ;)

For your old dusty cartridge. https://www.amazon.fr/BELGOM-05-0500-R%C3%A9novateur-Plastiques-500/dp/B0039JPUA4/ref=sr_1_7?s=automotive&ie=UTF8&qid=1531386315&sr=1-7&keywords=renovateur+plastique You can find it in all cars specialist shop ;)
-
Yes I saw that it's already done! There was no sound because jumper for audio was not in the right position. I remove the drilling helper from inside your box, this part is just to help you for drilling Leds holes and must be removed after hihi :) Your box shines now ;) Best regards Bruno

Good Morning, I just received @wired's box, upload new firmware and this one works fine now too ;) @Phatline, @dnode, @ErMangaver, @mrspring, @yogi, @scrubber, @gerald.wert Please update the firmware... http://www.midibox.org/dokuwiki/doku.php?id=midibox_tia#firmware1 and let me know ;) Best regards Bruno
