Midi-Fighter


Recommended Posts

May be jazzband but I could find no previous threads.

 

Anyone had a go with one of these?

 

Construction good?

 

How are arcade buttons as midi triggers? (I'd imagine you could get a good bit faster on these than more traditional midi triggers (unless you're araabmuzik, of course))

 

Yada yada.

I've used this as a midi controller before -

(and here's joe using the same usb converter for an ol' skool ps1 dual shock at a live gig)

And it worked a charm, so yeah I can't imagine you having any issues with those ....

Well for me it was cos I had everything at hand and didn't have any money to shell out for a midi controller. Though other than that why you'd favour one I don't know...

all the site shows is panels with buttons not even any sticks that could be interpreted as analog input :facepalm:

 

right, they're simply just an alternative to buttons or pads...

 

you could, oh... fire midi events with them :)

 

For those of us that grew up in the arcade that would translate to pretty fast event firing.

 

*shrug*

no shit, my point was that arcades have joysticks too, and the analog input from a joystick could easily substitue as a knob. theres only so much you can do with on/off switches how are you supposed to do a filter sweep for example you could do one with a hadouken.

 

just the buttons only these things are pretty useless

 

sorry to step on your spam campaign cause u obviously are someone behind these and are trying to sell them, maybe you should try and implement analog controls with joysticks then they might be worht something than just some cool looking dj toy

... every device need not do everything, and preferably won't (in my book at least). Perhaps you could do your filter sweeps with something else, eh?

RIGHT. SPOILT MY LOOT BRO. :facepalm:

and you could probably use something else to perform the simple act of a button press instead of some glorified hpster arcade looking thing with shiny lights, what's your point?

Right, that's completely valid.

 

My point is that you can't just dismiss the thing as completely useless just because there are other things that do it.

 

And some people like custom things... and build it yourself kits... and things that look neat. These traits don't make something inherently bad.

 

Meh.

I just finished up a DIY midifighter-inspired controller, powered by an Arduino. 12 buttons and 6 knobs & sliders (total). I tried to put 6 more buttons (18 total) using the analog inputs, which shorted the pots and gave a higher ADC value to trigger additional midi notes, but the current dips through all the other knobs so the values wonk out temporarily. What did work was using one of the digital inputs as a switch: when it's switched on, the knobs and sliders send one note, and they send different values if the switch is in another position. This effectively doubles the amount of inputs it has, bringing it to 24 (working) buttons and 12 knobs/sliders. I also laid the interface out in a pattern to mimic the ABL2 interface so I could easily acid. Excluding the reusable Arduino, it cost me about 30 bucks and two days.

 

Fucking ABL2, though...

 

Edit: uses big fat arcade buttons too.

Also, it sounds very interesting and I'd like to possibly make one.

 

Sure, it's in a box now to be brought back to campus, so within the next few days.

 

Writing that made me realize I could invert the wiring for the analog buttons. It'd short the pot to ground so it wouldn't overdraw. Probably would work.

30 bucks? I'm quite interested. I thought Japanese legit arcade buttons would be a bit more expensive than 30 dollars alone.

Sorry about the quality, my 1080p digital video camera apparently takes shitty pictures.

 

The two highest "keys" aren't functioning properly, along with the 4 upper row. I used knockoff arcade style buttons, and they're meh. The action is fine, but it "snaps" too loudly. If I could redesign it, I'd probably use these or maybe even the real deal (their products seem a bit overpriced and this clearly isn't factory direct, you could probably find them cheaper). The Cintra boards and spacers I had laying around and worked fine. Very happy with the Cintra, it's light, easily workable, not-too-glossy not-too-dull and still holds a grip. The open sides were a byproduct of laziness, technicality, and DIY aesthetic. Hasn't and shouldn't be problematic.

 

If you want schematics or code, just ask.

Pretty!

I used a modification of the code found here. It's attached. It uses two additional programs to interface with MIDI software: a serial to MIDI converter and a virtual MIDI port. It works surprisingly easy.

 

I saw on hackaday yesterday a HID-compatable Arduino (your computer will recognize it as an interface device and not an Arduino). This is very interesting and removes the two programs from the interface chain. Again, if I had to rebuild this, I'd certainly use this Arduino derivative.
