.AIFF FILES
This format is usually used with Apple computers. It stands for Audio Interchange File Format. The format is actually better used with Ensoniq wavesamples because the byte-ordering (the way the bytes are arranged in the file) is the same, whereas .WAV orders the bytes in an opposite way. Think of AIFF this way - it is “Apples sound file format.”

COMMON DIALOG
A standard Open or Save As Windows dialog that navigates Drives, Directories, and Files within DOS devices. Ensoniq Disk Tools uses these whenever possible; however, it uses a replacement when it becomes necessary to navigate Ensoniq devices as well.

DISK FILE
A file saved to your hard drive that stores all the parameters of an instrument read by Tools. See File Image.

DISK IMAGE
This is an Image of an entire disk of files, as defined in the EPS/ASR. The files contained within can be Instrument, Bank, Sequence, Song, MacroFile, System-Exclusive, Effects, or Backup Files. It comes in Giebler format (.ede or .eda), or GKH format (.gkh).

EFFECTS
The Ensoniq 16-Plus and ASR-10/88 have a built-in effects chip, which you can assign parameters per instrument and bank.

ENSONIQ DEVICE
Refers to a floppy disk or SCSI drive that is formatted to be read by the EPS/ASR/TS equipment.

FILE IMAGE
This is an Image of a single file as defined in the EPS/ASR. It can be an Instrument, Bank, Sequence, Song, MacroFile, System-Exclusive, Effects, or Backup File. It comes in Giebler format (.efe or .efa), or .GKH format (.ins or .gkh). These images can exist on their own, or reside inside a Disk Image file.

FRAGMENTATION
In most files, the data is arranged with the data being read one byte after the other; in other words, the information is in order. But certain files may have been worked with in such a way that the file is disarranged. The file works because there is a “table of contents” (called the FAT, or File Allocation Table) that arrange it. Such a file is called a Fragmented.

GIEBLER DISK IMAGE FORMAT
Giebler Enterprises introduced this file format. It really is a 512 byte header, and afterwards it contains the exact byte contents of the Ensoniq Disk File. Within the header there is a table that lists which blocks have all zeros, and which don’t. That way the file is only as large as it as to be. EPS images use the .EDE extension (max 1585 blocks); ASR images use .EDA (max 3167).

GIEBLER FILE IMAGE FORMAT
Giebler Enterprises introduced this file format. It really is a 512 byte header, and afterwards it contains the exact contents of the Ensoniq File. It can be an Instrument, Bank, Sequence, Song, Macro, System-Exclusive, Effects, or Backup File. EPS files use the .EDE extension, and ASR files use the .EDA extension. NOTE: the differences between an EPS and ASR file-type are minimal. Really, it specifies if the file has pertinent information relating to new parameters within the 16-Plus/ASR, or that the type of effect is and ASR or 16-Plus.

.GKH IMAGE
This format is the oldest, developed by a guy named Goh King Wah (what a name - thus the G K H format). It is a short header, followed by the exact contents of the Ensoniq file. There is no skip table, and the bytes do not follow 512 byte boundaries. To make it more confusing, files with this extension MAY BE A DISK IMAGE OR FILE IMAGE OF EPS OR ASR TYPE. Ensoniq Disk Tools’ rule is that .GKH should be Disk Images, and .INS files are File Images, and converts things that way. However, Ensoniq Disk Tools will recognize both types.

.INS FILE IMAGE
The .ins file extension was implemented by Michael Chen, the author of EPSDisk, a program that put together many of Goh King Wah’s programs. Michael needed a file type that would represent a File Image, and since by that time the Giebler utilities had come, he adapted the exact same header, but used a different extension. So a .ins file is exactly the same format as the Giebler .efe./,efa format.

INSTRUMENT
A unit on the EPS/ASR that contains up to 8 Layers and up to 127 wavesamples.

LAYER
A unit on the EPS/ASR that holds wavesamples across one keymap of the keyboard. You can have up to 8 layers in an INSTRUMENT.

OBJECT
A unit within an Ensoniq file - for Instruments, a Layer or Wavesample; for Songs, a Sequence or Track; for Banks, a Slot Location.

PATCH SELECT
A Ensoniq innovation that selects a pre-programmed group of layers from a pair of momentary onboard buttons.

RUBBER CHICKEN SOFTWARE CO.
The makers, developers, sole distributors or Ensoniq MIDI-Disk Tools for Windows. They also make samples for the EPS/ASR series, and other items, specifically for Ensoniq samplers.

SAMPLER NAME
This area tells you what kind of sampler the computer is expecting. Once you read the EPS/ASR through MIDI, the computer finds out for itself and changes this automatically.

SOUNDVERT
The original .WAV-to-Ensoniq program. Developed by Tim Dorcas, it inspired this program.

SYS-EX (or, more properly, System Exclusive)
A MIDI standard that communicate specific messages to specific instruments. Ensoniq MIDI-Disk Tools uses this to changes just about any parameter in the EPS/ASR.

TOOLBAR LIGHTS
These lights tell you (from the left) if the MIDI is turned on so the computer can receive MIDI signals, if MIDI is coming into the computer, and if MIDI is transmitting out of the computer.

.WAV FILES
This format was developed by Microsoft (who else). It is sometimes called RIFF (Resource Interchange File Format), in contrast to AIFF (Audio Interchange File Format). The Windows-Intel platform (PC) uses mostly .WAV files. Think of it this way - it is the “PC’s sound file format. .WAV Files cannot be looped, nor do they contain multiple wavesamples. There is another .WAV type called ADPCM, which is a compressed type of .WAV file. These are usually low-quality, and are very small in size. Ensoniq Disk Tools does not support these files - convert them using a Sample Editor such as SoundForge or CoolEdit, or Awave.

WAVE OVERVIEW
A function where you can view the entire waveform, as opposed to just part of it.

WAVESAMPLE
A unit on the EPS/ASR that holds a set of parameters affecting the wavedata, and also either the actual sample data or pointers to another wavesample that actually holds the data.
