Note Rush must be purchased separately on each platform’s app store, but you should only have to pay once per platform. Just make sure you sign in to the store using the same account.

Examples:

• If you purchase Note Rush on an iPhone then later buy an iPad, you can install Note Rush again on the iPad for free, because they both use Apple’s App Store.
• If you purchase Note Rush from Google Play on an Android phone then later switch to an iPhone, you will have to purchase again from Apple’s App Store.

The first note of each game checks the tuning of your instrument and confirms the microphone is working. You should see a microphone icon with a yellow volume meter moving up and down. If you don’t see this possible problems include a microphone permission issue, or a conflict with another app.

To fix microphone access conflicts with other apps:

Reboot your device to ensure no other apps are running in the background and interfering with the microphone:

1. Turn your device completely off and on again.
2. Try playing Note Rush again.

To check microphone permission:

iPhone/iPad:

1. On your device, open the main Settings app.
2. Tap Privacy.
3. Tap Microphone.
4. Find Note Rush in the list. If the Microphone permission is turned off (to the left), tap to move the switch to the right (it should turn green).
5. Turn your device completely off and on again.
6. Try playing Note Rush again.

Android:

1. On your device, open the main Settings app.
2. Tap Apps or Application Manager (depending on your device, this may look different).
3. Tap Note Rush.
4. Tap Permissions. If the Microphone permission is turned off (to the left), tap to move the switch to the right (it should turn green).
5. Turn your device completely off and on again.
6. Try playing Note Rush again.

Here’s a few things you can try to improve note detection.

Make sure you are giving Note Rush a clear starting note

Note Rush tunes itself to the pitch of the note it hears when you ‘Play X to start’ at the beginning of each game. This enables it to adapt to non-concert pitch instruments and out-of-tune pianos, but it’s important to play this note clearly and on-pitch (for variable-pitch instruments) or the whole round will be ‘off’.

If you are playing a concert pitch instrument you could try tapping the Skip Calibration button instead of playing the starting note and see if that helps.

Reduce background noises, including talking

Where possible, eliminate other background noises while you’re playing Note Rush. Talking over notes in particular can interfere with its ability to detect notes correctly.

Hold each note for longer

Try holding each note until detected rather than playing staccato.

Is your device in a case?

If so try taking it out (some cases can reduce microphone quality)

Move your device around

Try moving your device to different positions relative to the instrument. You could even try turning it upside-down to change where the microphone is pointed.

If you’ve been sitting your device on a piano music stand, try holding it instead. If this helps, try resting it on something padded rather than directly on the piano body.

Try another instrument

Try with a different instrument to see if the issue is with the instrument. Acoustic pianos tend to work better than keyboards because keyboards usually have less sustain. Don’t have another instrument? Try singing! (just to help identify the issue!)

Try another device

Try installing on a different phone or tablet to see if the problem is with your particular device. If it is, you could try updating the operating system to the latest available version.

Note Rush tries to filter out background sounds as much as possible, however sometimes it can’t tell a background pitch from an intentional note being played.

Reduce background sounds as much as possible, and if you’re still having issues, you can disable ‘Penalize Incorrect Guesses’ in Note Rush settings (tap the Settings cog at the top right of the home screen).

MIDI connectivity on mobile devices can be a bit tricky to get set up correctly. Here’s some tips that may help.

• Read the FAQ about MIDI instruments.
• If you’re using an iPhone or iPad, download the MIDI Wrench app (free) and use it to test whether the MIDI device is being detected at all, and whether notes played are being received.
• If you’re using an Android device, make sure you are using an OTG (‘On-The-Go’) adapter, and you may need to select the correct USB mode once it’s plugged in. This looks different on different devices, but try pulling down from the top of the screen or searching Settings for ‘USB peripheral mode’ or similar.
• If your MIDI keyboard is USB powered, the OTG or camera connection kit adapter may not be able to provide enough power for the keyboard to function properly. Connect a separate power cable to your keyboard, use an OTG/camera connection adapter that allows a charger to also be connected, or use a powered USB hub to provide the keyboard with the power it needs.
• Check the manual for your keyboard for any instructions related to MIDI mode. Sometimes there is a setting to switch between MIDI in/out and USB, or between standard MIDI and some proprietary protocol.
• Try a different OTG or camera connection kit adapter.
• If you are using a circular 5-pin MIDI in/out adapter, try a different one of those.
• Not all devices, particularly older Android phones, support MIDI correctly. If none of the above work, try using another phone or tablet.
