I guess the main problem with multi-format is that you will have to accomodate the LEDs for your pads somewhere close to the center, which is where the Marquardts have one of two contact pins. I'd say don't bother, and if I ever feel so inclined I can always come up with a similar layout for "proper" switches (and then include multiple footprints as on the latest BLM 16x4 v2 version).

Yes, all the TL1100 knockoffs are kind of crappy, and even the "original" E-Switch ones tend to go bad rather sooner than later. Rubber contacts are used in a number of Roland keyboards (for the actual piano keys), and yes I've had quite a few problems with these. ENIG plating might be a solution to the problem, but on top I'd rather press on something that gives me a more defined haptic feedback, so I never bothered too much with pads. I understand people go for the sexy look of these illuminated pads, and that's probably justification enough :-).

I agree, plus I am not convinced about the durability and longevity of these pads / the contact system these use. I would prefer a solution with proper switches.

Here are the dimensions for the mounting holes. Altitude is testing the prototype, I have PCBs available if anyone is interested.

Are you still looking for one? I have one spare that I am selling, if needed as a complete kit including duo colour LEDs and stuff. PM me if interested. Vi snakkes ilmenator

Dann kann man das so machen, korrekt.

Guys, it's kind of kristal='s "privilege" (or obligation) to run the bulk order. Many years back we found out the hard way that it can be very bad if a manufacturer / industry supplier is flooded with small orders from unknown hobbyists - they often shut the door to private / hobbyist's orders after such a wave. kristal= has since then established a relationship with ALBS, so let's count on him doing a bulk order again.

Good to hear. If anybody else needs pre-programmed PICs just let me know. I have just found my Willem programmer in one of the cardboard boxes left from my last removal.

Where are you located?

Ziemlich einfach - es gibt mindestens drei Gründe dafür: A) Für die meisten MIDIboxer macht es Sinn, mit der "neuesten, schnellsten" CPU zu starten, weil sie nicht genau wissen, wohin sie die Reise führen wird. Wenn sie mit dem selben Core später mal eine anspruchsvollere Applikation bauen wollen, dann steht dem nichts im Wege. Irgendwann kommt ein neuer SEQ, und ob dann der F1 Core noch für alles reicht? Preislich sind die Unterschiede gering (und ja, auch ein Unterschied von 100% ist "gering" bei einer Stückzahl von 1). B) Für die erfahrenen MIDIboxer macht es Sinn, sich auf eine Plattform für den "Support" konzentrieren zu können. Bei vielen unterschiedlichen Plattformen im Umlauf wird es schwierig den Überblick zu behalten wenn spezifische Fragen aufkommen. C) Für Tim/SmashTV macht es Sinn, sich auf eine Platine konzentrieren zu können, weil damit Lagerhaltungskosten reduziert werden, und damit letztlich die Gesamtkosten für ihn und uns.

Interesting... what's the schematic you're using?

You're welcome, it's nice to see that there is still some interest in this project. Unfortunately, life got in the way back in 2014, before it was 100% complete. Let's see how far we get this time

Hi there, currently the matrix does not allow for channel routing and event filtering. At the documented design stage, this would have only been possible for those inputs routed through the STFM or the (external) mergers (PIC 1688) anyway. Why? Well, everything that is related to routing is happening inside the FPGA, which is kind of "brainless". It is controlled by the STFM. In order to modify MIDI data in any way, that data would have to be routed through the STFM first, which is difficult: there are not enough available IO pins on the STFM board left. You could probably implement event filtering for two or so MIDI ports... USB MIDI has not been considered. But: you might expect a v2 later this year which has a virtual processor running on the FPGA. With this it should be possible to do some channel routing and event filtering, at least for a limited number of ports - depending on the number of UARTs that can still be implemented on the FPGA. However, this will not be a top priority. The main reason for the update is to increase MIDI port count to 64x64 and to make better use of the available real estate. It also means that the matrix itself will no longer be strictly MIDIbox based. The UI, however, will still be. And the whole thing will still be scalable and modular. Best, ilmenator

Sure, there should be a PIC based software in the repository. I built a MIDIbox version of the Stribe a few years ago, so I can confirm that TK's implemenattion is fully functional.

Superb! You should get paid by Novation for making their products more attractive...

So, did you change the Launch Pad Pro's firmware or did you modify the MIDIbox Seq V4 to get this to work??

It would help if you posted your location. A local builder is definitely something you want, in case the build runs into problems afterwards.

My personal opinion: Mutable Instruments Ambika with 4P filters.

OSHPark is great indeed, they have top notch quality PCBs. However, if you need larger size boards OSHpark can become quite expensive. Also note that shipping is only free within the US. However, for small boards their service can't be beaten. Psykhaze has already given a good overview on the rest of the pack from China mainly. For PCB design I would always recommend KICAD, which is free, open, and has turned into an amazing piece of software in the last two years. Before, I have worked with Target and with Eagle, both manufacturers that try to lure you with crippleware, i.e. the free versions are seriously limited, either in pad count or in board size. As latigid on mentioned, all these tools have rather steep learning curves, so in my opinion it just doesn't make sense to invest time into learning a software, only to eventually discover that you need more features later on. Because then you either have to spend the money or start learning again... There are also lots of tutorials available for KICAD as well.
