User manual KORG EX-8000

[. . . ] PROGRAMMABLE POLYPHONIC SYNiHE MODULE OWNER'S MANUAL KORG FEATURES OF THE KORG EX-8000 1 The EX-8000 is a 2U sized rackmountable 8-voice Polyphonrc Synthesizer Module, with a built-in Digital Waveform Generator System (D. W. G. S. ). The DWGS has sixteen digitally encoded waveforms stored in four 256 kilobit ROM chips. These waveforms are digitally encoded samples of actual acoustic instru. merits` recreated by additive synthesis techniques to enable more realistic sound synthesis: (The sixteen waveforms also include simple sawtooth and pulse waveforms such as " I'Y , l-7 " and " TL " which are found in conventional analog synthesizers. ) The EX-8000 is 2U-sized so it's rackmountable. [. . . ] Fine adjustment is performed by using the FACTOR parameter. !

The EX-8000's eight voices are assigned sequentially as notes are played. If you play more than eight notes, then the most recent notes will cancel out the earliest notes still sounding. In this mode, sounds using long release times will create an effect of "overlapping" notes, which will create a spacious sound. Synth Voices Used When one note is played, the eight voices are used sequentially. n POLY2 Mode This is most useful for certain instrumental sounds, and for sounds using polyphonic portamento effects. If a one note passage is being played, the first synth voice (out of eight) is used continuously. If two notes are played, the first two voices are used continuously, and so forth. Synth Voices Used When one note is played, the first voice is always used. When two or more notes are played, other voices also are used. WNISON 1, 2 Mode This mode assigns all eight voices to each key depression, following a "last note played" priority system. Because all eight voices are automatically detuned when this mode is selected, this produces a very fat, rich sound. This mode is useful when the EX-8000 is used for soloing or playing bass parts. UNISON 1 causes the envelope to retrigger every time a new key is pressed, regardless of other keys being held. UNISON 2 wilt result in single trigger operation (only the first key pressed will activate the envelope). Synth Voices Used All voices are used for each note played CREATING SOUNDS 3, Writing Programs to MemoryJ fl Features and Functions for Control Used to specify the program number. I Used to start writing programs. Shows presently selected program number. When this switch is set to ENABLE, memory write operation is enabled. 4 q Program Write Procedure Create a sound (as described in the previous section of this manual). I---ENABLE m DISABLE q Set the front panel WRITE switch to the ENABLE posision. WRITE q Press the WRITE key on the front panel. m At this time, the program number flashes. Flashing CREATING SOUNDS @I Use the NUMBER keys to select the program number where you want to store your sound. The new sound is stored in the specified memory location immediately after the program number selection. (Previous contents of the selected memory location are erased. ) Example: Storing your sound at program number 34. , m Display will show a dash in the right digit. (Waiting for input) m sr A selected parameter can be stored in memory with a program. It will be very helpful if you specify a parameter (e. g. , cutoff frequency) during programming which will be edited often during live performance. 4 Press CANCEL Your sound now occupies the memory space called program number 34.
