## KORG iMS-20 Reviews in United States

### ***** "Always The Best"
This is a one of a kind treasure. I bought this 5-6 yrs ago and I'm still finding ways to build new awesome synth presets. I may never be able to afford an original tactile analog synth, but this is great compensation. I haven't seen anything like it in the App Store since. There are other VSTs out there, but this one gives the biggest bang for the buck. It has: MIDI drum sequencer (5 drum voices) a mixer 16 song pads to mix in song mode it has dual oscillators it has patches envelop filters 2 Assignable KORG KAOOS touch pads
-- Tobias227, 2024-12-03

### ***** "I was afraid of this!"
Stop reading and buy this synth now! Simply amazing. 90 seconds into playing around with the synth blew me away, the sound, the layout, the functionality of everything is right at your fingertips. It draws you in and makes you want to explore. The synth is an indispensable tool in the hands of any real synthesist.
-- Ggnomind, 2024-04-23

### *---- "Not worth it at all"
The tempo knob, is not accurate at all, and there’s no way to manually put the tempo in. Massive short coming when you can have a keyboard raise up on your iPad. It does not import into GarageBand, you left to try and make music in their app… is wish I could return this app.
-- Genesha, 2023-11-12

### ***** "Classic Analog Synthesizer Sound"
This is my go to Synth for great sounds like Desert Winds or you can create dual layered leads ,..or deep growling basses. All kinds of risers and explosions are possible,…whatever Crazy sound effects you can imagine ,….you can figure out how to tweak it out of the MS-20.
-- Maxwellteks, 2023-07-30

### ***** "The best👍"
Korg the Number 1
-- randy el fantasma, 2023-01-18

### **--- "UPDATE"
Y’all need to update this!! It sounds great and just needs the UI to be redone. It’s pretty hard to use with how it’s designed right now. Also maybe make a mode where you can just use the synth and not have all the groovebox stuff in the way which can get annoying, I just want the synth most of the time, groovebox is nice but when I just want the synth it gets in the way of me just creating sounds.
-- parkourmasta, 2022-06-25

### **--- "Korg always leaves me hanging…"
Just got this and, I don’t know why I am surprised, but here I am, and this is another great example of a half baked product that the company obviously doesn’t care about maintaining. The interface is not clear and/or easy to figure out, the whole thing is rendering with obvious unintended overlap on the screen of my 2021 iPad Pro 11”, and the user manual does not even appear, when I select it in the menu. This really should be made illegal; if they don’t intend to keep supporting software in the future, a developer should be prevented from being able to sell it, unless there is a given and acknowledged disclaimer that the software will not be touched for maintenance updates. I’m giving it 2 stars because it sounds like it should, but missing 3 stars because the standalone version of the app no longer is functional as a compositional tool, because of obvious neglect by the devs at Korg. I feel VERY disappointed that I threw away $30 on this app. Thanks for nothing, Korg. 👎🏼👎🏼

### ***** "The best ... its simple."
Yep
-- kswanca, 2020-11-28

### **--- "Needs to be AUv3!"
Sorry but I don’t use Gadget and never will. It just doesn’t work for me. But your stand-alone synths are awesome and need to be AUv3!

Needs to be AUv3!
-- anickt, 2020-10-13

### ***** "Korg Has Done It The Best"
High price for an app but definitely a steal. Can I just say one word. MIDI! Put your iPad in an Alesis IOdock and connect a midi device. For example: MAudio keyboard etc. I am surprised they haven’t raised the price on this. The best time to catch it is during the holidays when apps normally go on sale. And thank you so much Korg for the continual updates.
-- RoadNinja007, 2020-10-08

### ****- "AUv3?"
Come on Korg, a synth really needs to be AUv3 these days. So, just do it already!
-- Tilden Thorne, 2020-07-07

### ***** "Stood The Test Of Time!!!"
Still my favorite app after all these years. Sooooo many things you can do with Korg-ims 20 it’s a Great app. Perfect if your a creative person.
-- blacktangibles, 2020-06-18

### *---- "No AB3 and very poor Midi Options"
It’s virtually impossible to use a controller with this app other than the built in keyboard. You can’t send Midi to it, which is whole reason I bought it. Why is Korg so far behind the times.
-- ScottFin, 2019-04-26

### ***** "Splendid"
A splendid reproduction, and delightful to tinkle with.
-- salamicat, 2019-03-20

### *---- "not install iphone"
why im1 install ok iphone.
this not ok.
give me back my money.
-- pyongx2, 2019-03-10

### ***** "Faithful to the original hardware"
This app undoubtedly captures the pure essence of the legendary MS-20! I've used Korg products for many years and I know their sound very well. This is the most practical way to get "that" sound in an affordable and user friendly way ... period. An amazing tool - so much fun too!!
-- Jahiv93, 2018-09-25

### **--- "No midi out or export"
Wanted to use this with my hardware ms-20 but no midi support out. Waste of money. Doesn't seem like Korg will add it.  The arp and sequencer are very cool what a shame.
-- truenels, 2018-06-13

### *---- "Abandonware"
Korg seems to have abandoned this app. No integration into Gadget or Audiounit compatibility.
-- 7Z7, 2018-05-31

### *---- "No AUv3 or ableton link support"
Painful to see such a great synth being shoved in closet wearing a hood and having the key for both flushed down the toilet. I hope a teenage mutant ninja turtle finds the programming power to unlock the beast from its shackles to let it play nice in the contemporary world of iOS music production with AUv3 compatibility 🐢
-- k9d, 2018-02-14

### ***-- "Gadget please"
Gadget please or a dedicated sequencer, need to sequence
-- Pnto, 2017-08-27
