☆ Guide to GuideBGMs ☆

GuideBGMs (guide background music) are audio files meant to be sung along with while recording to help keep you in-time and in-tune.

Generally, keeping your audio samples as consistant as possible allows for better synthesis. Tempo affects the length of the phones, and recording pitch affects both tone of voice and transitions between samples. While it's strongly recommended to record with a metronome of any kind, a guideBGM can provide not only the tempo, but also the pitch to match while singing.

How to Use

Step 1. Download one or more guideBGMs you want to use and place them where ever is convient for you. I recommend the guidebgm folder in your OREMO program files because it will be easy to find them. You can create subfolders inside this for more organization.

Step 2. Launch OREMO.

Step 3. Go to Options > Recording Style Settings.

Step 4. Click on the folder icon next to Guide Music File, find where you saved the guideBGM you wish to use, and select the .wav file, NOT the .txt file.

Step 5. Select either Automatic Recording 1 or Automatic Recording 2.

Automatic 1 will play the guideBGM only once when <R> is pressed, and you will move on to the next string manually.

Automatic 2 will play the guideBGM in a loop when <R> is pressed and automatically move to the next line after each play. You will have to press <SHIFT+R> to stop it.

Step 6. Return to the main application and hit <R> on your keyboard when you are ready to record. The guideBGM should play according to your settings.

Step 7. Repeat until the voicebank is fully recorded

Any guideBGM you use will be a little different, so if you want to use them, it's good to find the ones that work best for you. I made my own because I wanted ones with minimal distraction. Here's how they work:

  • Recording starts halfway through the first measure. The woodblock functions as a metronome, and the first piano note is for mental pitch matching.
  • Breathe in at the chime, then start singing with the first beat of the 2nd measure. Hold in time with the piano for as long as you need.
  • Recording stops halfway through the last measure, after the piano stops, so there's room for an extra mora at the end


  • Compatible with OREMO
  • Includes 4 beats at 100 and 120 BPM, and 8 beats at 120 BPM
  • Includes pitches C3 to C5
    • This covers most pitches that one might want to record at, but if you need to go higher or lower it's not too difficult to transpose your own voice.
  • Includes MIDI template files to customize your own


4 beats / 100 BPM / C3 - C5

4 beats / 120 BPM / C3 - C5

8 beats / 120 BPM / C3 - C5

Example of Usage

Demo'd here: CV at 100BPM, VCCV at 100BPM, CV at 120BPM, 5-mora VCV at 120BPM, efficiency VCV at 120BPM, all at D#3
