It is the Raspberry Pi 3 but should work with 4 and 5.

@@steffanjansenvanvuuren3257 oops I said the wrong board earlier. Edited the answer.

@@WoozleEffect The Raspberry Pi Pico is connected automatically when wired up to your iPad. Bluetooth controllers will work too but you have to select the device in each app’s settings.

Thanks for watching! The arcade buttons are around a dollar each on Amazon and the boards are ~$5. In all, I'd say it's around $30 if you have the tools and an enclosure. There are links in the description for most things. For the coding it took around 2 days to code, build ,and film the video. I leveraged some APIs I've used in the past.

Yeah, it does sound familiar, but it is nothing specific. Maybe it is similar to Cold As Ice by Foreigner or What A Fool Believes.

i want to make a laser harp and i have problems with making the sound

The sound is coming from the iPhone. I made a screen recording on the device and used that audio for the video.

​@@cristi6257 If you are creating an application that generates sound, you could wire in an audio jack and ran a cable to an amp, headphones, or audio interface. If you are making a MIDI controller it won't produce sound. It just controls the virtual instruments of the application you are using it with. Depending on the micro controller you use some of them also support audio over USB.

@@mobypixel do u have any idea how i con do this with some speakers?(jack plug)

@@mobypixel I want to make a laser harp, I use arduino leonardo, the idea behind it is that I have a laser diode and a photoresistor and the moment the laser wave no longer reaches the photoresistor I want it to make a sound and I would like to use some speakers to make the sound

Oh cool! I didn't know that.

Hey! Thanks, Kevin! That's high praise coming from you. Good luck with your videos!

Thanks homie! 🙌

Thanks, @soulyft! 🤜💥🤛

Thanks, Ryan! Congrats on the launch. 🚀

Haha, thanks @Byronic19134! We're spoiled for choice on the iOS synth front. And Sketch Audio just dropped another app today that's a Lo-Fi effect AUv3, Doctor Vibe.

Yes Krista does support exporting layer animations, but I have not tried it. I just saw there are some good tutorials about it on KZfaq. Good luck 🙌

Awesome! I'm glad it helped!

There are a couple of piano presets in the app, but I'm not sure if they are the M1 one. You're probably right.

You need Bluetooth enabled on the iPad, and then the app you are using needs to support USB MIDI. Usually there will be some drop down menu in the app to select your Bluetooth device. You can see it in Koala around 3:45

@@mobypixel cool. how is the latency on the raspberry pi pico?

It’s really good. I didn’t notice any delay when wired up.

I'm using Apple's camera connect kit that has an external lightning power line. That is what is powering the Arduino while keeping the iPhone charged. On newer iPads with USB-C you can use a USB power bank to send multiple USB devices to the iPad while powering them. So yes, you will need some external power supply for the Arduino. The iPhone's connecter won't send that voltage to your board.

@@mobypixel oh, so it gets power from the usb adapter? you don’t have to plug a do power supply into the onboard power jack?

@@eross21 That is correct. The Arduino is sending MIDI and getting power from the same Micro USB cable. The USB cable from the Arduino goes into the camera connect kit along with power from a lightning cable, and that plugs into the iPhone.

@@mobypixel oh perfect ! thanks so much

Thanks, @jdmaze1! Yeah, they did a great job with the presets.

Sure, you can make sprite with it. You could make different layers for each sprite and export them separately, but there isn't an option to animate between them in the app like Aseprite.

Thanks, James! I appreciate the kind words! 🙌

It's not too bad. You set it up in the minidexed.ini file: github.com/probonopd/MiniDexed/blob/afa72d21aa81a9876b3f9e50f3bd6f4cd56cdac0/src/minidexed.ini#L113 The other option is navigating with a rotary encoder like Floyd Steinberg did in his video. To see the Patch Name I navigated to the performances tab and selected it. I'm not sure of a shortcut for seeing the names if you are deep in the menu stack, but you can change patches with a button press.

@@mobypixel Thanks. I see two pins there for the encoder, so that would cover turning it, but nothing for the encoder button or built in switch... Is it defined as one of the other buttons? I don't really get how all those other buttons can be replaced with just an encoder, but I assume it has at least the usual built in button in the encoder to do something. I've looked at the documentation a few times but I haven't really got all that far with understanding it.

@@mobypixel Okay, I've found a bit in Wiki Files, that says "ButtonPinShortcut defines the pin that is used for rotating the rotary encoder knob while the button is pressed. Probably you will want the button that is built into the rotary encoder to be used for shortcuts." I really have no idea what that's trying to say so I guess I'll just have to try it and see what happens.

@@TooSlowTube Yeah, a the rotary encoder is an endlessly turning potentiometer that can be pressed as a momentary button. I think in MiniDexed one click selects and a double click goes back in the menu. I used one in my Teensy Synth build recently.

The determining factor is Xcode's required minimum version which is currently macOS 14.0, and the maximum version supported by the Mac. Typically I get a new Mac and it lasts for about 6-7 years before I can't upgrade to the latest Xcode version anymore, because it can no longer update to the latest macOS version. I'm on a 2021 M1 iMac and I'm hoping it lasts me for several more years. I would think any M1 machine and newer would last for a while but it's a gamble. These are the devices that currently support the latest macOS: support.apple.com/en-us/105113

Thanks, @evennorthug2585! Yeah, I wanted to make this a high level, 10,000 foot view of what it takes to build an iOS audio app. My other tutorials go into more detail about the actual coding parts--this is more of an introduction video with an AUv3 template at the end. MIDIKit uses CoreMIDI and Swift so it is multi-platform on Apple OS's like iOS, macOS, tvOS etc. You're right that MIDIKit is MIDI only. I'm using it to replace the built-in MIDI support in AudioKit. More specifically, I'm using it to receive messages from a MIDI Controller that I plugged into my device to play notes on the AppleSampler instrument. The MIDIKit Repo itself has some built-in demos and I also go into a little more detail about MIDIKit in this video: kzfaq.info/get/bejne/gLpdY7h1v6qlo4k.html AudioKit has been separated into individual Swift Packages so it should be smaller now. The AudioKit Cookbook (github.com/AudioKit/Cookbook ) is a great way to check out the current state of AudioKit as a whole. The core engine is still in the AudioKit package, but other parts have been moved: github.com/AudioKit

Thank you, Alex! I’m not planning on releasing this to the App Store, but it might be a piece of a larger app that I’ll be working on for the next few months. 🙌

@@mobypixel - okay, just let me know when you're willing to accept my money for cool beat pads.

Thanks, Dean! I appreciate it! 🤜💥🤛

Hey Marek! That's good to know. I saw where you were making some kind of groove box with the Pico on Twitter a while back. Yeah, Teensy is awesome! It does all the things well.

@@mobypixel teensys are great but would be even better if they were cheaper!

I'm not sure, but MiniDexed has a forum where I saw people talking about alternative screens. github.com/probonopd/MiniDexed/discussions

@@mobypixel Thanks

AudioKit released a Swift Playground drum pad example, but I don't know about any other ones. I'm sure some of these examples could work with copy and pasting in the code, but I don't personally have any experience with using Swift Playgrounds. Thanks for watching!

Thanks, @lucawiehe1995! To change the pitch of a sampler there are a few approaches you can take. AppleSampler has a variable named "tuning" that can be used to shift the entire instruments tuning i.e. instrument.tuning = 12.0 //to shift up an octave. I think the more robust option would be to create a custom AUPreset or EXS file and add the tuned chords to different MIDI notes. In GarageBand's AUSampler or Logic's Sampler, you can tune each note of the keyboard individually. So you could use the same sound file played on various MIDI notes with different tunings. I hope that makes sense.

That’s awesome! I’m glad it helped. 🙌

I have links to the ones I used in the description. The jumper wire pins came in a set and the Arcade connector spade terminals were separate.

@@mobypixel I see, thanks a lot!

That's cool! And pretty surprising for a big name like Korg. They also made a synth/game for the Nintendo DS. I know a lot of people also like Korg Gadget on iOS, but I haven tried it.

akai mpc also

Yes, there are some potentiometer examples in the Control Surface library. It typically requires one wire running to ground, one to power, and one to an analog pin on the microcontroller.

Nice! It’s got a chill funky vibe throughout. I dig it!

@@mobypixel Am very glad you knew Spanky's Quest SuperNintendo :)

It has an onscreen keyboard that you can use to play it. AudioKit Pro also has a free app called King of FM with a similar layout if you want to try the interface before buying.

Oh great. Am new to iPad music and have no iOS keyboard. Do you have any recommendations for my iPad for a good compatible keyboard. Thank you so much for your help

I used to have a Roland D50 synth and loved the sound banks

​@@petergregory6185 Plugging in a MIDI Controller with an iPad has a few considerations. A Bluetooth MIDI Controller should work, but you may experience some lag. If you have an iPad with USB-C you can plug in a powered USB hub to connect your MIDI Controller and other USB devices like a keyboard or mouse. If you have an iPad that uses a Lightning connector you will need Apple's camera connect kit to attach a MIDI Controller. If your iPad model needs the camera connect kit, make sure to get the adaptor that has lightning male on one side and USB & power female ports on the other side. As for the actual MIDI controller that comes down to personal preference and budget. I use Arturia but there are a lot of great options out there.f great options out there.

No, on Mac I just plug it in and it's detected automatically as a MIDI device. I used the Control Surface library, so they might be handling some of the MIDI routing behind the scenes.

So much thank u! I was trying to made with esp32 in wire way, but doesnt work… thanks for blowing my mind (laughts)
