Extract text from Ensoniq patch files (EFQ)
To convert EFQ patch files to another format, you need Awave Studio or other Audio software.
To convert other file formats to the "Synthesizer Patch File" file type, you need software like Awave Studio or a similar tool.
The .EFQ format is a highly proprietary patch, sequence, and system exclusive (SysEx) data file created for the Ensoniq SQ-1, SQ-2, and KS-32 digital synthesizers from the early 1990s. Musicians used these files to store voice parameters, custom sounds, and keyboard performance splits. The format is obsolete, but specialized audio translation tools like Awave Studio or Chicken Systems Translator can still read them. Ensoniq was a pioneering audio manufacturer, detailed extensively on Wikipedia.
Opening an .EFQ file natively requires the original 1990s hardware. It is a closed, binary format locked to specific vintage synthesizer architectures. Standard DAWs like Ableton Live, Logic Pro, or FL Studio cannot open them, and there is zero native playback support on modern PCs. The core disadvantage of this format is that the data only represents parameters - not actual audio waveforms. To use these sounds today, you must convert the .EFQ file into sampler-friendly formats like SF2 (SoundFont), NKI (Native Instruments Kontakt), or extract sequence data as standard MID files. Because the original file points to internal ROM waveforms physically inside the hardware, expect slight differences in tone, filter behavior, and modulation when exported to a modern software sampler.
Converting .EFQ files is notoriously difficult because standard online converters expect actual sound data (like WAV or MP3). .EFQ only contains mathematical parameters. Even if direct conversion fails due to the missing hardware ROM dependencies, our analyzer can inspect the embedded hex strings to confirm whether the file contains extractable MIDI sequences or just proprietary patch data.
Convert.Guru analyzes your EFQ file, detects the exact format, and lets you read the text inside.
Users also converted EUI, EFK and EFV files.
If you want to convert EFQ file to MP3, WAV, AAC, FLAC, OGG, WMA, M4A, AIFF, OPUS, ALAC, APE or WV, you can use Awave Studio or similar software from the "Synthesizer Patch & Sequence Data" category. In the File menu, look for Save As… or Export….
To convert MIDI, AAC, TTA, AU, WV, DTS, MID, FLAC, RA, MP3, PCM or WAV files to EFQ, try Awave Studio or another comparable tool in the "Synthesizer Patch & Sequence Data" category.
The history of Convert.Guru began over 25 years ago in California with Tom Simondi’s file-format database. A former contributor to Space Shuttle development and a software pioneer of the 1980s, Simondi established a trusted resource for file type analysis that was even referenced by Microsoft Windows XP. Today, we use modern technology to process and convert thousands of file formats while continually improving our EFQ converter.
