### 1/5 — Useless

*2026-02-23, version 1.9.12*

I’m really frustrated with this app.  There is no option to show the editor or desktop, and when I go to add a layout it asks for a host address rather than allowing me to load the layout file that is saved on my iPad.

### 1/5 — 软件没有用

*2025-08-30*

千万不要现在我研究了很久都没有连接上，软件无法使用。

### 1/5 — Osc con iPad 18.4

*2025-03-01, version 1.9.12*

Se queda con el logo de inicio durante unos segundos, y despues se cierra. La app la estoy ejecutamdo desde un Ipad.

### 1/5 — Evang

*2023-09-08, version 1.9.12*

Hola como puedo hacer una devolución del programa, no funciona,

### 3/5 — please name the app icons properly

*2023-06-13, version 1.9.12*

when not using it often the two app versions cannot be easily identified by their app icons.

it could be as easy as adding a 1 and 2 to their names or in the icons

### 1/5 — Limitado.

*2023-06-13, version 1.9.12*

O app e bom, porém ele não é tão fácil personalizar, só tem um programa editor que é bem fraco, sem muito recursos. Arrependi da compra.

### 5/5 — muito bom, recomendo demais

*2022-12-03, version 1.9.12*

Melhor app que ja vi para isso, incrível criar os presets como quiser

### 3/5 — Not sync with host

*2022-11-30*

Looking for host not working, after add layout across itunes application not view layout…!!! Please fix this issue!!!!

### 1/5 — Will Not Control Ableton Live From iPad

*2022-10-18, version 1.9.12*

I’ve tried everything, followed the online “manual” (such as it is) and TouchOSC from my iPad will not send any midi control to Ableton Live. Installed TouchOSC Bridge on my desktop PC… multiple times, TouchOSC finds TouchOSC Bridge my desktop, connects to it with no issue, configured Ableton Live to correctly to send and receive MIDI using the TouchOSC Bridge but no midi commands from sent from my iPad using TouchOSC  register in Ableton Live. I have wasted HOURS fighting with this app, did send in a contact request but as of yet no response. Even at one point installed Protokol, using the OSC protocol was able to see the midi messages being sent but STILL… no midi changes in Ableton. I WANT MY FIVE DOLLARS BACK!!!!

### 1/5 — Abandoned app for more cash grab!

*2021-11-02, version 1.9.12*

Instead of providing existing users with an update or special price for the new version the developer just renamed it and ABANDONED existing users!
