TouchOSC Mk1 Customer Insights

1. (I have IPv6 disabled on the LAN so it should not even be getting that address at all.) If you cannot fix this, it's useless to me and I need a refund.Desperately needs an update to bring it into the latest versions of Android.

2. Look forward to finding more uses for this!The app only picks up the cellular IPv6 address and not the WiFi IPv4 address so it cannot connect to the computers on the local LAN.

3. The IP address shown in the App is a 10.0.0.0 type, while the rest of my devices are 192.168.0.* Any help would be appreciated.So far so good although I've yet to get the sync feature to work (just emailing myself the layout file).

4. i hope the developers work on it to keep it fully updated and compatible with the latest Androids.No matter what I do, I am unable to get TouchOSC to connect to my network.

5. It doesn't act on files with touchosc extension, etc..i bought it based on recommendations and also because it is (was?) a very useful app not only for music but to control anything, including robotics, like DIY Arduino projects and that's the main reason why i wanted it.

6. It is a closed network with static IPs for each device, and I am able to connect between any of my other devices, but TouchOSC just will not send anything to my PC.

7. Its there any way to create an option to launch right into a layout rather than the top level configuration menu? Thinking ahead to end user implementation.The reviews made me wary but decided to try it out.

8. Really hope the color picker will soon be availableGreat app on iOS, but until they add MIDI device support it's unfortunately useless on Android.

9. I highly recommend it, its been around for a long time, and it has always been stable.It is a nice and useful app, but it desperately needs a more user friendly and up-to-date UI.

10. The file picker to locate layouts is too basic (e.g., no SD card access, no cloud) which makes transfer of layouts from PC to tablet a pain.

11. Nowhere near material design.Nice app but would love to have a colour picker instead of just a couple simple colours.
