what is a .efv file?

An Ensoniq VFX-SD file is saved in a format developed by Ensoniq for a particular model of its line of digital synthesizer products. The EFV format is implemented as the default audio data encoding and compressions specifications integrated into these EFV files. An EFV file is generally classified as an audio file and is affixed with the .efv extension. The Ensoniq VFX-SD device is an electronic synthesizer used to play and create digital music. This device is implemented with firmware that uses these EFV files whenever a user accesses certain functionalities available in the keyboard. Each EFV file corresponding to the buttons and keys pressed by the user on the digital synthesizer is then located by the firmware, because it needs to reference the data stored in those associated EFV files. The content of an EFV file may include pitch settings, tone configurations and recorded music samples among other details. Musical notations and metadata info required by the audio content of an EFV file may also be stored in the EFV format.

VFX-SD is a professional quality sequencer capacitating 25,000 to 75,000 notes, and can hold up to 60 sequences and songs. The sequencer's operating system is loaded into the floppy disk from the RAM memory of the instrument, allowing easy loading of Ensoniq's new operating system. The VFX-SD's sequencer is versatile indeed because its floppy disk can also be used in storing whole songs, single sequence, single presets, 20-presets bank, single sounds, sets of 6 or sets of 30 sounds, and whole banks (60 seconds). Although it is not compatible with MS-DOS, niche industry sprang up to accommodate the needs of the musicians. The software has also a new drum and percussion sounds that includes 24 drum kits, totally compatible with the original VFX sound library.

It displays large fluorescent with two rows of 40 alpha-numeric characters that automatically shows various parameters in a given section and instantly access to each one through placing the buttons over and under it. This model is more reliable that ESQ-1 due to electronic hardware design revision. It is the first product to feature Ensoniq's patented Polypressure Keyboard technology which has a polyphonic aftertouch wherein each key pressed will independently respond to other keys aftertouch. Aftertouch can also control various modulation parameters like the LFO. Although SQ-80 is a classic analog or digital hybrid of the late eighties, it lacks built-in effects.

a word of warning

Be careful not to rename the extension on .efv files, or any other files. This will not change the file type. Only special conversion software can change a file from one file type to another.

what is a file extension?

A file extension is the set of three or four characters at the end of a filename; in this case, .efv. File extensions tell you what type of file it is, and tell Windows what programs can open it. Windows often associates a default program to each file extension, so that when you double-click the file, the program launches automatically. When that program is no longer on your PC, you can sometimes get an error when you try to open the associated file.
