Adjusting the following settings may help resolve the issue.
- Right-click the DAW icon and open Properties.
- Go to [Compatibility] > [Change high DPI settings].

¶ In Logic Pro, the Plugin Window Extended Beyond the Screen and Cannot Be Resized
- For AU plugins, double-clicking an empty area in the transport section will automatically resize the window.

- In linked groups, note and parameter control point edits are shared. To unlink them, right-click on the note group and select [Unlink Group]. → "Note Groups"
- When duplicating a track, selecting [Duplicate Track (Unlinked)] will prevent the duplicated note groups from being linked. → "Arrangement"
¶ “Format not supported” Message Appears When Trying to Import Audio
- Are you using the option/dialog intended for importing project files instead of audio files?
To import audio, either drag and drop the file into Synthesizer V Studio 2 Pro or Create a New Instrumental Track.
¶ Audio Export Menu Missing
Audio can be exported from the Render panel instead of the File menu. → "Rendering and Export"
¶ Tempo from MIDI or MusicXML Not Imported
When importing, selecting [New Project] will close the current project and create a new project with the tempo from the MIDI or MusicXML applied.
If [New Tracks] is selected, only a track will be added to the existing project, so the current project's tempo takes priority and the tempo from the MIDI or MusicXML will not be imported.
¶ Tempo and Playback Position Differ in ARA Bridge Mode in Logic Pro
- Please double-check that the ARA Bridge Link is illuminated and that dummy audio is placed on the ARA track. → ARA Bridge Mode Setup
- Display the tempo lane in your Logic Pro project, and if the first tempo marker is not at the beginning of the project, move it to the start.
Normally, when setting the overall project tempo, Logic Pro automatically creates a tempo marker at the beginning of the project. However, if this marker has been moved to a later position, the tempo and playback position may not sync correctly.
¶ I want to delete the cache
- Please refer to "Rendering Cache" in the "Render and Export" section.
¶ Render & Playback
¶ No Vocals Are Being Generated:
- Please note that trial voices only allow rendering up to 40 notes per note group.
- Please check if a voice has been selected for the track. → "Track and Voice Setup"
- Please confirm in the Product Manager that the voice is properly registered.
- Please make sure there are no overlapping notes within the same note group. → "Note Input Precautions"
- Open the Arrangement Area and check if there are any tracks that are soloed or muted. → "Arrangement"
¶ Unusual Pronunciation:
- Please refer to "Note Input Precautions".
- You can edit phonemes displayed above notes by double-clicking them. → "Piano Roll"
- You can register word pronunciations using the dictionary function. → "Dictionary Panel"
- The issue may be improved by adjusting the phoneme length. → "Pronunciation"
- The issue may be improved by re-taking the voice timing or timbre with the AI Retakes feature. → "AI Retakes"
¶ Bounce in Your DAW and There is No Audio:
- Please make sure that both the DAW track and the Synthesizer V Studio 2 Pro track are not muted.
- Please note that trial voices do not allow bouncing audio.
- In Full ARA mode, only audio from the Synth Track will be bounced; audio from Local Tracks will not. → "Full ARA Mode Setup"
¶ Playback Stops Midway in Reaper
- In Reaper, playback automatically stops at the end of the project. Since Synthesizer V Studio 2 Pro inputs notes inside the plugin rather than on the DAW timeline, Reaper may misjudge the project length, causing playback to stop prematurely.
- Adding an audio file on another track or placing an empty MIDI clip as a dummy will allow playback to continue up to that point.
¶ In Bitwig Studio, Sound Only Plays When the Track Is Selected
- If the plugin only produces sound when the track using Synthesizer V Studio 2 Pro is selected, and the sound stops when another track is selected, please change the track’s monitoring setting in Bitwig to Off (Never monitor input).
