*** Stunningly high-quality piano and a full range of keyboard sound engines ***
KORG Module has five dedicated sound engines, providing a number of high-quality sounds that can be played back on your iOS using the "NATIVE ENGINE”. These engines feature technology that was developed for KORG's historic line of workstations and synthesizers including: Acoustic Piano, Electric Piano, Clav, Organ, Multi, and Hybrid. Each display has carefully selected parameters, making it convenient and easy to adjust the sounds. We’ve also carefully ensured ideal playability and designed the system for ultra-low latency. Once you experience the quality of the sounds being produced from the slim body of your iPad, you'll agree that Module is radically different than anything else currently on the market.

*** With just an iPad/iPhone and the new microKEY, you can enjoy great sound anywhere ***
KORG Module and the microKEY are the best possible combination for a mobile performance environment. With the new microKEY which supports a damper, or the microKEY Air which provides a wireless connection via Bluetooth MIDI, your iPad can transform into a high-quality sound module. In your room, in a practice studio, or performing on stage,, it's easy to set up and immerse yourself in a superb playing experience wherever you are. Of course you can also use any MIDI keyboard that can connect to your iPad via Apple Lightning - USB camera adapter. The velocity curve function conforms the sound to your playing dynamics, so you'll be able to perform comfortably using any MIDI keyboard. Even if you don't have a MIDI keyboard, you can use the apps on-screen keyboard, phrase function, or MIDI player to play the sounds. The MIDI player can load and play standard MIDI files for your listening enjoyment.

*** Mobile music production in tandem with KORG Gadget ***
You can also use the high-quality KORG Module sounds inside KORG Gadget, the mobile music production app. If you have Module and Gadget, the five tools Salzburg, Montreal, Alexandria, Firenze, and Glasgow are added inside, allowing access the same way as Gadget. These five powerful gadgets will add even more variety to your music productions, raising your music to the next level. Whether for performance or for production, both of these apps deliver ultimate sound.

Babble on One ,


A few days ago, I gave a one star, because a couple of my IAPs were only playing white noise. I tried reloading several times to no avail. After two hours of repeating the process, the IAPs reloaded properly. All is now well. These IAPs counterparts had disappeared from Gadget, also. As soon as Module correctly restored the IAPs, they reappeared in Gadget. Perhaps it was due to high internet traffic? I don’t know… This only occurred on my iPhone (SE2020, running 14.6), the iPads never experienced this problem.
I also mentioned the difficulty of interfacing with tech support. I received notice this morning that they responded to my comments. I clicked the notice, which took me to the App Store Module page, but could not find their reply.
Since the IAPs eventually reloaded correctly and a reply was made (I’ll continue looking for it), my faith is restored in Korg’s app developers… I have used Korg hardware for decades and have been VERY impressed with the quality of the iOS apps (of which I have purchased all but a couple)!
P.S. Devs, please get Stephen to sign off on an iKarma… 😉

Hi, we're sorry for the inconvenience. Could you report the details of the issue via https://support.korguser.net/hc/en-us/requests/new ?

It’s ok, needs a couple things

The sounds are pretty good. I like that I can use it live on stage. Unfortunately there are two issues, I’ve used it on both my phone and my iPad, but it constantly drops the connection with both midi and usb mid song causing me to have to disconnect and reconnect it to get a connection. Not very good as my band has contracts with casinos in Nevada that pay very well and if we can’t perform, they won’t renew our contract. I also use my iPad to run sound at the same time I’m playing and when I switch apps to adjust something the Korg app stops working. Other apps allow me to do that. I have to adjust the sound then reopen the Korg app. So now I have to use two separate iPads to prevent this from happening. Also, the sounds are good, but are limited as to how much I can adjust them. Need more mids? Nope. Need to cut lows? Nope. Not in all of the sounds anyway. Need drawbars on your organ? Nope. Just the presets for you. Want to add distortion to your instrument? Compression? Nope. That’s only allowed on some of the instruments. I’m keeping the app because I’m hoping some of the issues I have will be addressed at some point. Don’t get me wrong, the sounds so far are better than the majority of other apps. But my Roland keyboards have the ability to adjust way more, it’s just a lot harder to do and they’re big and heavy to lug around.

Great sounds and more

There's a bunch of good sounds in this one, and there's also lots of organs, which I highly recommend if you don't have an iPad. There's all these pianos and some extra sounds, but you should get the regular version instead of "Standard for iPhone" since you'll probably have native iPad support and the ability to get more sounds. However, I have some concerns. I purchased this app during a sale and it was supposed to be less but it must've paid full price for it. I also had this happen with ARP ODYSSEi as well, which was supposed to be $15. And where is the free Tape pack? The only thing close is the Tape Keyboard, but I think it's pianos and keyed instruments. Is it an iPad exclusive in app purchase? Anyway, go and try it, get some organ sounds, and don't be scared of the huge size; you can just install the gadgets and uninstall Module afterwards, if you have Gadget. I'd like some answers too. Lots of great organ sounds!
