THR Librarian app
A patch editor and librarian for your Yamaha THR amplifier.
Yamaha's THR series are terrific little amplifiers. Unfortunately they only have the ability to store 5 patches on-board. The only way you can access more than 5 patches is hook your amp up to a PC or Mac and install Yamaha's THR Editor application. In addition, some of the amplifier effects such as the compressor are only accessible through Yamaha's PC application.
Introducing THR Librarian. Simply attach your Android phone or tablet to your amplifier using a USB On-The-Go adapter, and you can switch between patches and edit them right from your device.
What you need:
- An Android phone or Tablet that supports USB On-The-Go.
- A Yamaha THR5, THR5A, THR10, THR10C or THR10X amplifier (THR-II series not currently supported).
- The USB cable that came with your amplifier.
- A USB OTG adapter. If your phone has a USB Micro-AB connector, you will need an adapter like this one: http://a.co/3mustjw. If your phone has a USB Type-C connector, you will need an adapter like this one: http://a.co/fBZA0vM.
The free version of the app allows you to test your connection and load the built-in demo patches. A single in-app purchase is offered if you wish to unlock the full feature set, which will allow you to:
- Download patches from your amplifier.
- Modify all of the parameters available on your amp, including ones not directly accessible such as the compressor. The editor also changes in real-time as you adjust the parameters on your amp.
- Organize your patches into groups. Tag your favorite patches, or create a set list for a live performance.
- Use the hotkey feature in combination with a Bluetooth MIDI or HID foot switch (e.g. https://www.airturn.com/407.html) for hands-free patch and effect switching.
- Import patches from .YDP and .YDP files.
- Rename and delete patches.
- Share patches via email, Google Drive, Android Beam, etc.
In the unlikely event that THR Librarian is unable to connect to your amplifier:
1) Verify your amplifier is able to connect to Yamaha's THR Editor on your PC.
2) Verify your phone/tablet supports USB OTG using one of the free OTG checker apps in the Play Store.
3) Try plugging a USB thumb drive into your USB OTG adapter; your phone/tablet should automatically recognize the drive. Note if you have a OnePlus device, USB OTG is disabled by default, and must be enabled under Settings/Advanced. It also automatically turns off 10 minutes after it is enabled. You can permanently enable it by following the instructions here: https://www.xda-developers.com/enable-always-on-otg-oxygenos/.
If these checks all succeed and you are still not able to get the app to connect, please contact us directly at firstname.lastname@example.org. Note we are unable to provide support for connection issues through the Play Store review channel, as it only permits a single character-limited response.
