[. . . ] Resampling lets you build up extremely dense sounds or record a sequence of notes to be played back with a single key. There are three resampling modes, 16 bit, 18 bit and 20 bit. Use 16 bit mode for monophonic or duophonic passages. The 18 and 20 bit modes give you more headroom when playing many notes at once. If clipping occurs, use a higher bit mode. v 1. 4. To Set the Sample Source: Press the Sample Manage key. The LED illuminates and the main screen appears. The "Create Sample" screen appears. Move the cursor to "Source" using the cursor keys. Select the desired sampling source using the Data Entry Control or INC/DEC keys. Press the Exit key to return to the Sample Manage screen. 5. Dither Dither is a technique used in digital systems to improve audio performance by adding noise to the least significant data bits. Dither should be used whenever a digital number is converted to a smaller number (for instance when converting 20 bits to 16 bits). EOS samples at 16 bit linear, so dither should be turned On when digitally sampling from a source that has more than 16 bits, for example when sampling a 24 bit AES signal or when sampling from a 20 bit ADAT machine. Dither can be either On or Off when analog sampling (the audio performance is the same). 180 E-MU Systems 5 - Sample Manage New Sample ADC Gain ADC stands for Analog-to-Digital Converter. The ADC Gain field defines the dynamic range for the sample. Setting too high an ADC gain may cause clipping. Set the analog sample level with the Data Entry Control or INC/ DEC keys so that the left and right side meters indicate optimum sampling level. Play the sound to be sampled and observe the bar graph display. The signal level should be set so that the peak bar comes close to the extreme right side without actually reaching it. The gain is adjustable from -18 dB to +30 dB in 2 dB steps. This control has no effect on the digital input. v 1. To Set the ADC Gain: Press the Sample Manage key. The LED illuminates and the main screen appears. [. . . ] · PC Compatibles - The Emulator has been tested with IBM PC compatible computers using the Adaptec model 1542C SCSI option card. Sound files can be transferred between a PC computer and the Emulator using Sound ForgeTM, RecycleTM or other sample editing software. · Macintosh - Sound files can be transferred between a Macintosh computer and the Emulator using RecycleTM, Transfer StationTM, AlchemyTM or other digital sample editing software. The Emulator is able to access approved Macintosh internal CD-ROM drives with CD-ROMs containing EOS compatible files. [. . . ]
