User manual KORG EX-800

[. . . ] It saves valuable space and provides a wide range of sound synthesis possibilities when used in conjunction with your MIDI synthesizer. Thank you and congratulations on your choice of the KORG EX-800 Polyphonic Synthe Module. To obtain optimum performance, please read this manual carefully before using this synthesizer. 3 Uses two Digital Oscillators, analog noise generator, and VCF and VCA modules for sound synthesis. You can enjoy the uniqueness of digital sound plus quick and logical sound synthesis as in analog control. 4 5 The EX-800 accepts Initial Touch (key velocity) and After Touch (channel pressure) data, so real-time control of output volume, timbre and pitch modulation is at your fingertips when used with a synthesizer featuring these functions. A programmable digital delay is included to store clear stereo effects (Chorus, Doubling, Short Delay, and Long Delay) for each of 64 tone colors in the programmer. 6 7 Auto Bend is included for more realistic synthesis of human voice and brass sounds. Key Assign mode provides two polyphonic modes and two unison modes, which are effective for playing solo or bass parts or using Portamento. [. . . ] If this is set to the same value as the sustain level, then the envelope becomes a conventional ADSR type. VALUE This parameter controls how long it takes for the VCF EG output voltage to change from the break point level to the sustain level. 1 SLOPE TIME1 m SUS (Level) VALUE SUSTAIN LEVEL 0 This parameter determines the VCF EG output voltage after the slope time. 3II JI VALUE l-l l-l I Max. RELEASE TIME Short This parameter determines how long it takes for the VCF EG output voltage to fall to zero level after the note is released on the keyboard. I 3: VALUE :: I Long 1 DEGREE OF TIMBRE CHANGE Controls the degree of timbre change according to the speed of playing a note on the keyboard. When the value is made larger, the degree of timbre change becomes greater. (Actually, change of EG output becomes larger. ) Set valtie at "0" when using a MIDI keyboard without Touch Sensitivity. Max. change CREATINGSOUNDS Ex: When the value is changed for a fixed envelope. (No change) Time RVCA EG m ATK (Rate) VALUE ATTACK TIME Controls how long it takes for the volume to rise from zero to its maximum level after a note is played on the keyboard. VALUE Determines how long it takes for the volume to fall from its maximum attack level to the break point level. I!. : I DECAY TIME Short t 1 3; t 1 Long q B P (Break Point Level) VALUE BREAK POINT LEVEL Determines the level at which volume stops dropping during the decay. If this is set to the same value as the sustain level, then the envelope becomes a conventional ADSR type (as if it had no break point or slope parameters). VALUE Determines how long it takes for volume to change from the break point level to the sustain level. Note that if the break point is lower than the sustain level, then the slope functions as a second attack. If the break point is higher than sustain, then slope functions as a second decay. SLOPE TIME Short E=3tt I I 3: Second attack :: I Long Second decay VALUE Determines the level at which volume is held after the attack, Uecay, and slope phases are completed, for as long as the note is held down on the keyboard. :: I 3I JI SUSTAIN LEVEL 0 I Max. REL (Rate) Determines how long it takes for the sound to fade away after you release the note on the keyboard. VALUE RELEASE TIME Short I -I 3 I7 1-l I I Long I CREATING SOUNDS IiN VEL VALUE DEGREE OF VOLUME CHANGE No change Control the degree of volume change according to the speed of playing a note on the keyboard. 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-800 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. (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. The previous contents of the space have been erased. r - - - - - _ _ _ _ _ _ _ _ _ _ - _ _ _ - _ - - - _ - - - `1 [ Caution: 1 Be sure to return the front panel WRITE switch to 1 the DISABLE position after completing this proce-' I dure. This helps protect against accidental over; writing (erasure) of memory contents.
