## Thesys Reviews in United States

### ***** "Dope midi sequences with parameters!"
This is great app.
-- Oceans in space, 2023-06-28

### ***** "Great stuff"
How can you how can you delete something, on iPad - on computer it’s right click. Not able to on iOS.

Edit - nvm I figured it out. Long press. Great stuff.
-- DaMacMaclure, 2021-05-29

### ***** "Fun!"
The zoom function is very helpful! Overall an excellent sequencer with lots of possibilities plus it’s AU. Awesome like all of SB apps!
-- anickt, 2020-11-23

### ***** "Complete app!"
Very fun app. Easy to get started and deep enough to keep me focused. The customer service is also exceptional. Worthy purchase. Daily use.
-- Sound Bettor, 2020-07-06

### *---- "Hate the GUI"
This would be fine on desktop. The worst for working on an iPad.
-- CedarPrince, 2020-01-14

### *---- "Change to AU is good, but makes UI even more unusable"
Sugarbytes, put a little effort into this please... AU UI is horribly small!
-- MusixMonkey, 2019-03-13

### ***** "Great AUv3 MIDI Sequencer"
The update to the app is an excellent upgrade to the functionality of the app. You can easily create all sorts of musical mayhem by running multiple instances of the app and can change sequences on the fly via the GUI or use MIDI to control the app’s parameters.
-- polarpaul, 2019-03-13

### **--- "No way to import midi?"
Can’t open midi files from within the app or in iOS file share “copy to”. Just like all the other sugarbytes apps, low resolution, and works well with just about no other apps. Not having a file folder accessible from AudioCopy or AudioShare kind of makes using your apps unbearably tedious, terrible to incorporate into work flow. 
   Your VST plugins all work great, hire a guy like that for your iOS versions and you’ll have some of the best apps.
-- whydoyoumakememakeanickname, 2018-12-20

### ***-- "The best step sequencer, maddeningly tiny interface"
This is the best featured step sequencer in iOS, to this day. Has a bunch of modulation lanes, 32 steps, independent lengths for different parameters, scale quantize, scalar transpose, song mode, dj-style midi effects. All amazing, next level stuff, crammed into the most uselessly tiny interface, and ill conceived zoom workarounds. Be ready for bumping adjacent controls all the time and screwing up your sequence. I use it sometimes, and it ends up sounding great, but I loathe the experience. It doesn’t need to be this tiny, there is all kinds of wasted space, and needlessly compacted, dangerous to mix up groups of buttons, in fields of unused white space. It was ported from the desktop, and was never designed for a touch screen. If you could expand the sequencers to fill the screen you would be set, I think. Replace the dreadful PC key modifiers, Cmd, Ctrl, Alt, with traditional touch interface modifiers, like tap and hold, double tap, etc.

In an effort to use the app, I’ve gone to great lengths to midi map the controls to a midi controller, but, there is no way to reuse the midi mappings from one project to another, and there is no default mapping. 

I would avoid this app on anything except the 12.9” iPads.
-- Chinchilla Wafers, 2018-12-17

### ***-- "Still great, but it's time for an update"
This is still one of the best midi sequencers in terms of features, but it needs an update so it integrates better with live performances. MIDI clocking exists, but does not play nice with Ableton Link, so unless all apps are using MIDI clocking, Thesys has to be piped into the mix the old fashioned way. SugarBytes has been all over Ableton Link with their other apps...it's time to give Thesys some of that goodness. Also, needs a new idea with the user interface. As mentioned in other reviews, controls are itsy-bitsy, even on a 12" iPad Pro. With a little TLC, this is a five-star app that will be a main work-horse in mobile music for a long time.
