6 - Sample Edit

Sample Edit

O Tip: Entering the Sample Edit module resets the EOS sound engine. You can use this feature as a kind of “Panic Button” to turn off stuck MIDI notes or reset other screens. You could even set an Assignable Key to perform this function.

Sample Edit

The Sample Edit menu allows you to modify the actual sample data in order to perform functions such as: sample looping, sample truncation and splicing, equalization, time compression, sample rate conversion and many others. In the Sample Edit module we are working with the most basic element of the EOS hierarchy, the sample. It is important to note that every one of these functions except basic looping PERMANENTLY modifies the sample data. If you must maintain an original version of the sample, make a copy of the sample and edit that preserving the original.

Any sample in the bank can be selected from the main Sample Edit screen (shown above) using the data entry control, INC/DEC keys or numeric keypad.

The Sample Edit menu contains six main submenus:

Utilities. Cut, Copy, Paste, Truncation and Taper

Tools 1. Looping Controls, Loop Type, Digital Tuning, Sample Rate Conversion, and Sample Calculator

Tools 2. DC Filter, Swap Left and Right channels, Stereo<->Mono conversion, Reverse Sample, and Sample Integrity

Tools 3. Gain Change, Compressor, Parametric EQ, FIR (Phase Linear) filter, and Aphex Aural Exciter

Tools 4. Transform Multiplication, Doppler/Pan, Time Compression/ Expansion, Pitch Change, Bit Converter, and Beat Munger

UNDO! Allows you to undo any sample editing process.

Background: The Scrub Wheel

Background: The Scrub Wheel

The Scrub Wheel is a great function that allows you to use the controller's pitch wheel in many Sample Edit functions to quickly move through a sound, similar in concept to rocking the reels of a reel-to-reel tape recorder. The scrub wheel makes it easy to locate a particular section of a sound because you are able to hear the sound as you move through it.

To use the scrub wheel, move the pitch wheel of your MIDI keyboard while in a Sample Edit function such as Truncation or Looping. If the pitch wheel is moved slightly forward, the sound will play slowly through its length. If the wheel is pushed forward all the way, the sound will play through faster. If the wheel is moved backwards (towards you) the sound will play backwards through the sound. The scrub wheel operates like the accelerator on your car: the harder you press it, the faster it goes.
