In this episode of DIY or Buy I will be showing you how I created my own launchpad. That means I will show you how I combined a design idea with 3D Prints, WS2812 LEDs, tactile switches and an Arduino to create a proper MIDI instrument. While building I will also tell you a bit about a keyboard matrix and in the end determine what advantages the DIY Launchpad offers. Let's get started!

@DJlegionuk 5 лет назад

HI, I have made a few midi devices and had a few suggestions and comments if you do not mind. I would aways suggest using a teensy when working with midi as it has midi built in with a very good library of commands. When working with midi and addressable leds I would try to avoid neo pixel style leds as they can cause problems with timming, so I found using spi based addressable led like the apa102 with fastled work a lot better and are a lot quicker and this will help reduce latency. My last one is the buttons you chose need a lot of force to press and you will find using them tiring compared to a good tactile switch designed for a lighter touch. Now I did very much like the enclosure and the button mat you made, I thought the actual design was very good and as always an excellent video from you. To take this to the next stage I would add a routine that can switch on the led with commands from the midi software and not just from the keypresse. The teensy library had a routine called on note on and on note off that would handle all midi commands coming in and then you just need to switch on or off the correct led. Using velocity you could change the brightness or colour.

You could even reduce the number of IO-Pins by using a Shift-Register for one side of the buttons. Great Video though :-)

@johnfrancisdoe1563 5 лет назад

Luus135 A 4017 Johnson counter could do the 10 row scanning with one switch and two pins (clock and reset). Extending it to the 20x20 matrix to control one switch and 3 LEDs in each position of a 10x10 matrix (8x8 plus side buttons) would probably need a different counter chip. A 50-output row counter (2 μC pins) and, 2 sense column inputs and 6 LED driving outputs could do the whole matrix with 10 μC pins, with 20μs to process each row. For bonus, add force sensing button arrangements at the cost of more complex buttons and much faster scanning (as you now need to measure the time between each button reaching two depths). This becomes the velocity number in MIDI and changes how loud each sound is.

Nice video, definitely got me thinking about a few things for some projects I'm working on! Though, you could also, if you had used an Arduino with the ATmega32u4 chip, had set up your Arduino as an HID controller to emulate a keyboard, or even make it as a USB-Midi device directly using the MIDIUSB library. This works because the 32u4 chip has built in USB support, and can therefore act as a range of different USB devices.

@DonLafontaine62 5 лет назад

@Chaoddity 5 лет назад

I was thinking the same thing. I have a cheapo Korg drumpad and it features velocity, hold/roll/flam... Also the way he is multiplexing... couldnt it mess up if he played more than one button at the same time?

@GglSux 5 лет назад

@@Chaoddity Admittedly I don't know anything about this. But I was just thinking of how this could be done "in general" . And if I'm not mistaken, this(his) method is that the "pad" is polling/scanning "row by row" (or column by column). And keys that are pressed on the "currently scanned" row (or column) are "read out" (and stored or "sent out") before jumping to the next row (or column) to "read out" the keys pressed in that one. If this is how it's done, You "simply" avoid collisions by only actually "reading out" 1 row at a time. And since every "key" in a row is a member of a unique column, You simply check "which columns" that have registered "presses"...And other keys in that column can not "interfere" because they are not in the "scanned" row. ((or vice versa if You scan "columns" instead of rows)) The downside to this method is of course that it "splits" it's "scanning frequency" over how many rows (or columns) You "scan" possibly demanding a very high "scanning rate". Since it has to be able to scan off every row (or column) in a time short enough to actually make it feel like You can strike and release multiple keys simultaneously (e.g. a "chord"). And it must feel as if they can be "struck" and released as "1 movement" , and not that You feel as if You have to "hold" the "cord" to avoid the "pad" missing to "read" one of the pressed keys... At least that's what I believe... Apologies for my verbose attempt at explaining how I think it (could) works. Best regards

@stephenborntrager6542 5 лет назад

@@GglSux That is correct. He should have no issues detecting multiple key presses after the diode mod. Scanning rate should not be a problem either. The lack of velocity is the flaw of this design. (Let alone aftertouch...)

Velocity-sensitive pads are usually done with a PCB pattern similar to this: cdn-learn.adafruit.com/assets/assets/000/012/730/original/adafruit_products_1616top_LRG.jpg?1386359520. And then you have rubber pads themselves with conductive layer on the bottom (usually carbon or graphite-based, I believe). Then, the more you press on the pad, the bigger the contact it makes and the smaller the resistance is between corresponding sets of PCB traces. While making custom PCB's is quite easy nowadays for hobbyists, making custom rubber pads with a conductive layer on the bottom sounds like quite a hassle. You can buy 4x4 silicone keypads from Adafruit but they're all of a predefined size you can't change

@@urugulu1656 I believe that you refer to the cheap Chinese digital calipers - I own one for a few years, and first year I was frustrated as f*ck, given the fact how fast that crap consumed batteries even while not turned on. Quick googling later I found out that there is a design flaw in all these cheap calipers, that drains the battery even when off. What I did was simply disassembled the plastic part where the display and circuit board is found, cut one of the traces from the battery to chip, installed a small DIP push button, drilled a small hole in the plastic for the tip of button to stick out, and hotglued it in place. Works like a charm! I used like three pairs of batteries in first year. Now it's year 4 on the same batteries and no worries!

@lucasthompson1650 5 лет назад

@Artūrs Savickis Ha! I did the same thing last year because I got sick of trying to find a cheap unit that didn't use that same board/chipset/bug combo. The actual bug is that if the calliper registers any change in measurement (while "powered off") it will trigger the soft power-on - and as these aren't exactly the most precise instruments of their ilk, you can turn it off with the soft power-off switch while it is reading 0.00mm, wave it around in the air like a magic wand for a few seconds, and see it power back up because it is now reading that "new" measurement of 0.00mm … because like a lot of cheap digital scales, it's keeping an extra digit hidden for reasons that still baffle me. So, what actually happened is when you turned it off it was reading 0.00mm but actually measuring something like 0.003mm, and when you waved it around it started measuring 0.004mm, which triggered the soft power-on bug, and displayed "0.00mm" because some marketing guy thinks you'll trust the tool more if you don't know about that extra precision digit that is used mostly (as far as I can tell) for some rounding functions when you switch back and forth from metric to imperial units. I haven't had to swap a battery since putting the little manual DIP switch in either. I've seen other people put a small flat spring under the battery, snap the battery lid clip, and put a chunk of duct tape over the lid instead, essentially making the battery itself a sort of pressure switch … and as the duct tape relaxes it acts like a sleep timer to turn the unit off if you forget to. I prefer the switch, but this method might be easier for some people.

@Wander4P 5 лет назад

@@lucasthompson1650 @Artūrs Savickis Interesting info. I recently replace the battery on mine for the second time, so I decided to keep the battery in the case until I use it. But the switch solution sounds much more convenient; I'll have to see if I have a switch small enough lying around.

If it's called a launchpad then you should be able to launch a rocket or fly a drone with it.

If you used an Arduino with real USB not just USB Serial you wouldn't need that LoopMIDI nonsense.

@stephenborntrager6542 5 лет назад

How would the digital interface be handled in this case? The OS will still require a device driver for the device to be recognized as MIDI, and DIY drivers are almost prohibitively expensive.

@Tosta3000LPs 5 лет назад

You can use a standard device class in your USB descriptor. Those device classes are described in the USB specification and therefore drivers for this kind of peripherals are already built into all major operating systems. A standard MIDI device doesn't require any special drivers for its basic functionality. So if you use a microcontroller like the AtMega32u4, which has built in USB, you can implement a MIDI controller without the need of any extra software on your PC.

@@PixelyIon It depends what you value your time at. If your time is "free" then sure its always going to be cheaper to solder some perf-board. And if you design a modular button board, you can just make it so that the same PCB is used throughout the design (keeping it in the 100mm2 limit). Same with the LED strips. That $35 order from JLC saves you 2~3hrs of soldering (I mean of course you still have to solder the parts to the PCB but its faster) then its worth it. Unless you value your time at less than $12/hr.

@iGerman 5 лет назад

You didn't do the MIDI In capabilities at all, buttons just light up independently from MIDI, unlike a real Launchpad, where each button lights up with needed color with a command from a computer, that's how they do the lightshows on RU-vid. You could also find a hacked bootloader for the Arduino to just detect as a midi device, those usually work nice, with no need of loopmidi or anything else. If you had all the buttons (64+16) assigned to correct notes and MIDI commands (the upper round buttons) same as a real Launchpad, you could select Launchpad in the MIDI options of FL Studio, and set it to your device, and it would work exactly like a launchpad. And you've just made a button matrix with LED that happens to output MIDI, that's not a Launchpad. At this instance of your build, the winner is clearly a buy, since your 'Launchpad' is literally just a a button matrix with LED that happens to output MIDI. But I think your build is still impressive, considering that you did it all in one day for ~50 eur, it's not bad at all!
