Sample Length

This parameter defines the amount of sampling (recording) time prior to sampling. The maximum available length depends on the amount of memory available and the sampling rate.

v To Set the Sample Length:

1.Press the Sample Manage key. The LED illuminates and the main screen appears.

2.Press the New function key (F3). The “Create Sample” display appears.

3.Move the cursor to “Length” using the cursor keys.

4.Set the desired sample length using the Data Entry Control, or INC/ DEC keys. The display shows the amount of available sampling time on the line immediately below the sample length.

5.Press the Exit key to return to the Sample Manage screen or Arm or Force to begin sampling.

Arm Sample Trigger

The Arm function sets the sampling mode to Arm. This means that the sampling is ready to begin as soon as the sound you are sampling exceeds the sampling threshold level (as defined in the Threshold field). Once selected, you are ready to begin sampling. EOS starts sampling when the threshold level is met.

v To Arm Sampling:

1.Press the Sample Manage key. The LED illuminates and the main screen appears.

2.Press the New function key (F3). The Create Sample display appears.

3.Press the Arm function key (F5) to arm sampling.

Sampling starts when the input signal exceeds the programmed threshold.

v To Stop Sampling:

1.Press Stop (F1), Enter or Exit to stop sampling before the programmed sample length is reached.

Force Sample Trigger

The Force sampling mode causes sampling to begin immediately (without waiting to exceed the threshold or pressing a key on the keyboard).

v To Force Sampling:

1.Press the Sample Manage key. The LED illuminates and the main screen appears.

2.Press the New function key (F3). The Create Sample display appears.

3.Press the Force function key (F6) to force sampling. Sampling will commence immediately.

v To Stop Sampling:

1.Press Stop (F1), Enter or Exit to stop sampling before the programmed sample length is reached.

Keyboard Sample Trigger

The Keyboard Trigger mode initiates sampling when you play a specified MIDI note. Sampling continues as long as the key is pressed and stops when the key is released (or the selected sample length is reached). Keyboard triggered sampling has several uses:

•Automatic “punch-in/punch-out” using a MIDI sequencer to initiate sampling via note-on/note-off events. This makes it easy to integrate “live” vocal or guitar parts into your MIDI sequences.

•Turns the Emulator into a digital multitrack recorder. Assign the lowest note to be the trigger key. Select resample. Sample length to maximum. Now press and hold the key while playing the keyboard with your left hand. Assign the sample to the trigger key, select another preset and record track two…and repeat the process. You have 64 or 128 tracks, depending on how many voices in your Emulator.

v To Trigger Sampling from a Key Depression:

1.Press the Sample Manage key. The LED illuminates and the main screen appears.

2.Press the New function key (F3). The Create Sample display appears.

3.Move the cursor to Trig Key and select the key using the Data Entry Control. INC/DEC keys or the keyboard.

4.Move the cursor to Chan and select the MIDI Channel for the trigger key using the Data Entry Control, or INC/DEC keys.

5.Press the Key function key (F4) to enable Key Sample Trigger. A pop-up dialog box appears informing you that sampling is armed.

v To Stop Sampling:

1.Press Stop (F1), Enter or Exit to stop sampling before the programmed sample length is reached.

Automatic Parameters

Monitor On/Off

With Monitor turned On, you can monitor the input source through the main outputs before, during and after sampling takes place. As a rule, you want to leave the Monitor on so that you can monitor your sample quality. On occasion there may be instances, such as a feedback loop in the mixing board, where you would want to turn sample monitor Off.

Automatic Parameters

After sampling, the automatic parameters screen appears. You will perform certain sample processing functions on every sample you take. EOS can automatically perform these processes for you when you decide to keep it. After taking the sample you have three choices for what to do next: Dispose, Keep, and Place. This section describes these options and the automatic DSP operations performed on the sample. If clipping occurred during sampling, the display informs you at this time.

Dispose: Discards the sample and returns you to the New Sample menu.

Keep: Keeps the sample and performs the auto-DSP functions, but does not auto-place the sample. Returns you to the New Sample menu.

Place: Keeps the sample, performs the auto-DSP functions and auto-place functions, then returns you to the New Sample menu. When Place is selected, the sample is automatically placed in the target preset, group and range defined. See Auto-Placement Parameters.

Automatic Digital Signal Processing Operations

The automatic DSP parameters are as follows:

Truncate: (Off, Start, End, Both). Automatically truncates the beginning, the end, or both the beginning and end of the sample. The point or points at which the sample is truncated is defined by the Zero Crossing Threshold parameter in the Master, Misc module.

Auto Normalize: (Off, Absolute, Relative) . Automatically increases the amplitude of a sample until the largest peak reaches 100% of full scale. Relative mode increases the amplitude of stereo samples until the largest peak of one side reaches 100%. Both sides maintain their proper amplitude relationship. Absolute mode increases the left and right samples to full level independently. Absolute and Relative have no effect when sampling in mono.

Auto Loop: (Off, Whole, 1/2, 1/2 + xfd, 1/3, 1/3 + xfd, 1/4, 1/4 + xfd, 1/8, 1/8 + xfd).

This function automatically loops and autocorrelates the sample, then crossfade loops it if selected. Matching the loop length to the type of sample is important for getting the best results from auto loop. Ensemble sounds are notoriously hard to loop and are best looped manually.

Automatic Parameters

Auto Looping

Lengths

Select the auto looping length to match the type of sound. Loop on sections of the sound where the tone and amplitude are fairly static.

Crossfade looping smoothly crossfades between the waves on either side of the loop so that the data at the loop splice points are identical. Since Crossfade looping permanently modifies the sample data, you may want to turn this feature off when it is important to maintain the integrity of the data. Auto-crossfade is a linear crossfade and sets the crossfade size to 1/2 the loop length. Experiment with auto-loop using 1/4 to 1/3 sized loops to start. In most cases, you'll find that auto-loop produces amazingly good results.

Crossfade Looping uses data from around the loop start point and cross fades this data into the area around the loop end point.

Automatic Parameters

•White Key* Voice: A new sample will be placed on the lowest available white key beginning at the original key you select (C1 is the default starting key). Each new sample will create a new voice.

•1 Key* Voice: A new sample will be placed on the lowest available white or black key beginning at the original key you select (C1 is the default starting key). Each new sample will create a new voice.

•2-24 Key* Voice: New samples will be placed over a keyboard range consisting of the number of keys selected. You can select the starting key by manually setting the original key (C1 is the default starting key). Each new sample will create a new voice.

v To Create an Auto-Multisample:

This function works especially well for sampling other synthesizers.

1.Press the Sample Manage key. The LED illuminates and the main screen appears.

2.Press the New function key (F3). The Create Sample display appears.

3.Set up the sampling parameters such as sample length, sample source.

4.Take the sample. The auto-placement screen appears.

5.Press the Original Key on your MIDI keyboard.

6.Set Truncate to Both, Normalize to Relative, Loop to 1/4 + xfade.

7.Set Range to auto* Multisample.

8.Set the Target Preset to an empty location.

9.Press Place. You will be asked to name the preset (if it was empty).

10.Name the preset and press OK. EOS performs the DSP functions, then auto-places the sample.

11.If you wish to take additional samples do so now. Simply define the original key using your MIDI keyboard then press Place after taking each sample.
