THR Librarian Customer Insights

1. Really impressed so far though.Bought a THR10C a few weeks after Yamaha started to distribute them in the UK and have thought of selling it many times due to the lack of flexibility of editing patches outside Yamaha's own PC/Mac software.

2. It would be good to have a few more library management options, like adding a label to all patches within a YDL on import and being able to select lots of patches easily if you want to delete several of them at a time.

3. Glad I found this app, cause my laptop wont see the amp.3rd party app to bridge the gap that yamaha didn't create one? all i can say is: thank you for what you do!! works pretty solid.

4. Works perfectly and allows easy access to all setting available via the Yamaha computer app.

5. This is perfect - just what I've been looking for! Being able to disable the inbuilt Yamaha cabinet sims and use 3rd party sims transforms the THR into a fantastic recording tool.

6. Thanks and well done!Good but missing something Overall this app is good does all I want it to except you can't adjust the overall volume output you can only adjust the master volume for the gain, otherwise I would have given 5 stars.

7. Works as intended, but Yamaha needs to fix cranked up volume issue when loading presets.

8. Works again, thanks support team.Better than I expected, better than the Yamaha app.

9. It would be good to see the developer release an update which would allow for overall volume control via the app then this app would be complete.Great app, really straightforward to use but lots of control options.

10. It'd be nice if there was an option to save a library other than 'share' but it works... so thank you very much!Ever since I upgraded the app the amp can't connect.

11. Editing patches and selecting patches in real time is so easy and patch changes, as far as i can tell, are instantaneous.
