FAQ (Frequently Asked Questions)


Q: What is a MIDI track?
An Instrument (MIDI) track has one virtual instrument of your choice assigned to it and offers a flexible way of recording and editing notes.
Q: How do I assign instruments to it?
Tapping the instrument icon on a track brings up the instrument rack Micro Sonic, which offers a selection of instruments in its instrument browser. Tap an instrument to load it.
Q: What is an Audio track?
An Audio track contains audio files (waveforms), such as microphone recordings and imported or pasted audio files.
Q: How do I edit Audio material?
The Tools panel offers various re-arranging options as well as Pitch Shift and Time-stretch. For more precise editing, double tap an audio event to open the Sample Editor.
Q: How do I add and remove tracks?
There are three buttons on your track list (below all tracks, if there are any). Tap the - DELETE button to delete your selected track, or choose the + ADD to add a new audio or MIDI track. Alternatively, you can double tap an empty spot in the track list or drag & drop an instrument from the MediaBay. Press the duplicate button to create a copy of the selected track, including all its properties.
Q: How do I rename a track?
Open the track Inspector. Tap the top panel with your track's color and a rename dialog will pop up.
Q: Where do I find the mixer?
The mixer button is located at the top left of your screen. Tapping it will bring up as many channels as there are tracks in your project, along with an additional master channel.


Q: How do I record using the keyboard?
Create a MIDI track. Make sure that recording is enabled on it. Tap the Keys button, which brings up the keyboard. You can toggle between the keyboard and drum pads, depending on what you wish to record with. Tap the Record button and start playing. Once you're done, tap it again.
Q: How do I use the metronome?
Tap the metronome button next to the record button to switch it on / off. The click gain can be adjusted in the setup menu. Note: If you record audio material with the metronome turned on, make sure you use earphones, or the metronome clicks will be recorded into your project.
Q: How do I change my project's tempo?
Tap the display showing the BPM (beats per minute) count and a signature (e.g. 4/4). Slide across the number in the tempo category. For more precise tempo adjustments, use the + / - buttons. Alternatively, you can tap your desired tempo on the Tap Tempo button.

File handling

Q: Why is there no save button?
Cubasis automatically saves your work every 30 seconds, after every recording, when it's closed and when you turn off the display. If you don't want your file to be overwritten, open the MediaBay, select your project and tap the Duplicate button, which will duplicate your project in its current state. You can always go back to that state by loading the duplicated project.
Q: How do I create a new project?
Open the MediaBay and tap the "New Project" button at the bottom, or select the Projects folder, go to Templates and double tap one of the project templates.
Q: How do I export a project from Cubasis?
Open the MediaBay and select the Mixdown category. Tap Create Mixdown and choose the desired format. The exported file will be placed in the mixdown category, regardless of file type.
Q: How do I import files from another device or the cloud?
There are several methods to import a file into the MediaBay:
  • Copy into the Cubasis 3 folder
    Use any file manager app (such as the Files app on iOS) to copy files into the Cubasis 3 directory (on Android it’s /Android/data/com.steinberg.cubasis3/files/Cubasis 3). Cubasis will automatically sort the files into the respective folders and list them in the MediaBay.
  • ZIP files are unpacked automatically by Cubasis.
  • Device to device transfer
    AirDrop on iOS, or Android Beam can be used to quickly transfer files between two devices that support the same standard.
  • Cloud drives
    Cloud services such as Dropbox, Google Drive or iCloud (iOS only) can be used to transfer files between devices and to open them with Cubasis.
  • iTunes File Sharing
    The Finder on a Mac or iTunes on a PC can be used to access the Cubasis folder.
  • Import button
    Tap the MediaBay's import button to import files from the Files app,
    the Music app or AudioShare on iOS.
Q: How do I open a Cubasis project with Cubase on my computer?
  • Install the Cubasis Importer for Cubase on your computer
  • Transfer the project to your computer via your preferred sharing method.
  • The project arrives as .zip file, containing a .cpb (Cubasis Project) file and all audio files used in the project.
  • Unzip the file and launch Cubase.
  • In the Cubase menu, go to File -> Import -> Cubasis.
  • A file browser dialog will appear. Select the .cpb file.


Q: How do I add effects?
Open the Inspector. Choose Insert or Send Effects. Tap a slot and choose your desired effect type. Tap the e icon to modify your effect.
Q: What is the difference between insert and send effects?
Insert effects apply to the selected track only; Send effects are global. To learn about effect types in general, read here.
Q: What is a compressor or a limiter?
This chapter explains all effect types and how they work.


Q: Why do I hear nothing?
  • Readjust your device volume by using the volume buttons at the side of your mobile device.
  • Make sure your track is not muted.
  • Open the mixer. Make sure all channel's volume faders are adjusted properly. To reset a fader, double tap it.
  • If none of the above helps, try to quit Cubasis from the app switcher and restart it, or restart your device.
Q: Why is nothing being recorded?
Make sure that the track you want to record on has recording enabled. Also, make sure Cubasis has permission to access the microphone:
  • On iOS, open the Settings app, scroll down to Cubasis 3 and enable Microphone
  • On Android, open the Settings app, go to Apps, All Apps, Cubasis 3, Permissions, Microphone, and set it to Allow.
Note: If you are using external recording equipment, check whether it is set up for your track. Open the Inspector and choose MIDI Connections or Audio input (depending on the track type). Flick through the options available until the name of your connected hardware appears.
Q: I want to install Cubasis on another device. Do I have to pay again for it?
No. If you are using the same account (Apple ID or Google account) on the store (App Store or Play Store) for both devices, installing another copy will cost you nothing. Simply open the App Store or Play Store and search for Cubasis 3. The store remembers your purchase, displays a download icon instead of a buy button and lets you install the app for free again.
Q: If I delete Cubasis, do I lose all of my work?
Yes on iOS, no on Android. On iOS, deleting an app removes all of its locally stored data too and you would have to manually backup your files to retain them. There are many ways to backup, such as AirDrop, the iOS Files app, iTunes File Sharing, iCloud, Dropbox, Google Drive and more.
On Android 8 and 9, deleting an app retains its folder (/Android/data/com.steinberg.cubasis3/files/Cubasis 3) on the disk. On Android 10 and later, when deleting an app, you are presented with the option to “keep app data”.
Q: I'm having performance issues.
There are many different ways to increase your device's performance:
  • Use the DSP meter in the Inspector to get a realtime impression of Cubasis' current Digital Signal Processing load.
  • Go to SetupAudio, set the latency to the largest value (iOS only), enable multi-core processing and set the guard buffer to max.
  • If you are working with a large project containing a lot of notes, try the decreasing the polyphony of the track's instruments.
  • Freeze tracks.
  • When using pitch shift or time-stretch, set the algorithm to Mobile.
  • Combine effects: Avoid using multiple insert effects of the same type. Try using one send effect for multiple tracks, if possible. You can still adjust the each track's mix individually. The reverb effect is a prime example, as it requires the most CPU and is best used as a send or even a master insert.
  • Quit apps running in the background. To terminate an app, open the app switcher and swipe an app up to quit it.
  • Airplane mode is recommended to minimize CPU load even more.
  • Plugging in your device's power adapter may increase its speed since it might not be trying to save battery power.
