Early preview
What SynSound can't do yet
SynSound is new. Editing, mixing, bouncing and saving work end to end; these are next on the list.
Choose an audio interface
It records from your computer's default input and plays through its default output for now.
Record a MIDI keyboard
Draw and edit MIDI today; playing notes in from a keyboard is coming.
Open Pro Tools sessions
AAF, OMF and .ptx sessions don't open yet: bring in the audio files instead.

FAQ
Questions, answered
Is SynSound really free?
Yes. SynSound is free while it's an early preview, with no account and no subscription.
Can I record with it?
Yes, from your computer's default audio input. Choosing a specific audio interface and buffer size, and recording from a MIDI keyboard, are coming next.
Will my plugins work?
On the Mac and Windows apps, VST3 and CLAP plugins load, and on the Mac Audio Units too, each with its own editor and saved with the session. The browser version uses the 27 built-in plugins.
Can it open Pro Tools sessions?
Not yet. AAF, OMF and .ptx sessions don't open, so bring in the session's audio files instead. MIDI files and audio in all common formats import.
Are my files uploaded anywhere?
No. The online version opens files straight from your computer and works on them in the browser. Nothing is sent to Syntera Labs.
What does early preview mean?
SynSound is new and changing fast. Save your work often and keep copies of important sessions and recordings.
