User manual KORG EA1

[. . . ] In order to enjoy long and trouble-free use, please read this manual carefully and use the instrument correctly. E 2 To ensure long, trouble-free operation, please read this manual carefully. Precautions Location Using the unit in the following locations can result in a malfunction. • In direct sunlight • Locations of extreme temperature or humidity • Excessively dusty or dirty locations • Locations of excessive vibration Power supply Please connect the designated AC adaptor to an AC outlet of the correct voltage. Do not connect it to an AC outlet of voltage other than that for which your unit is intended. Interference with other electrical devices This product contains a microcomputer. [. . . ] The modulated sound will be output from OSC2 The tone and volume of Ring Modulation may vary depending on the phase difference between OSC1 and OSC2. • Oscillator Sync OSC 1 WAVE OSC 2 WAVE OSC 1 Output OSC 2 Output . . . Audio In Sync This type of modulation forcibly resets the OSC2 waveform by synchronizing its pitch to the pitch of OSC1. Moving the pitch of OSC2 will produce the popular "sync lead" sound. • Decimator OSC 1 WAVE OSC 2 Pitch (Sampling Freq) Decimater OSC 1 Output OSC 2 Output , , This type of modulation reproduces the OSC1 waveform at the sampling frequency of OSC2. When OSC Mod is set to Decimator, the basic waveform of OSC2 will be ignored. Filter The filter processes the sound produced by the oscillator to make it less bright, etc. Cutoff frequency EG Int > 0 EG Int OSC 1 Output OSC 2 Output Cutoff Cutoff Trigger on Cutoff frequency Decay Time EG Int < 0 EG Int Decay Trigger on Time Cutoff 0 Hz . . . Overtones higher than the cutoff frequency will be cut, making the sound more mellow. If Cutoff and EG Int are set to 0, you will hear virtually no sound. Ring Mod These parameters adjust the volume level and distortion effect. Distortion On, Off Turn distortion on/off. Distortion is an effect that intentionally distorts the sound to produce a hard sound even from a mellow waveform. It is highly effective to raise the resonance and use distortion. Level Adjust the volume. 0. . . 100 Effect Here you can apply effects to the sound. Type Select Tempo Delay, Chorus/Flanger The Depth and Time knobs will edit the effect that is selected by Type Select. Tempo Delay settings Set the Type Select button to Tempo Delay, and adjust the delay. Delay is an effect that plays back a time-delayed version of the original signal, and is also known as "echo. " Tempo Delay is a delay that can automatically synchronize the delay time to the tempo of a pattern. If the MIDI Clock parameter is set to "Ext" (external), the delay time can also be synchronized to the clock of an external device. (Refer to p. 39 "Synchronizing the EA-1 and an external MIDI device. ") • Depth (delay depth) 0. . . 100 Adjust the depth of the delay and the amount of feedback (the number of delay repeats). Rotating the knob toward the right will increase the level of the delayed sound and the amount of feedback. Raising the Depth excessively may cause the sound to distort. 25 4. Pattern mode ○○○○○○○○○○○○○○○○○○○○○○○○○○○○○○○○○○○○○○○○○○ Resonance 0. . . 100 • Time (delay time) This parameter adds character to the sound by boosting the region around the cutoff frequency. If you raise the resonance and turn the Cutoff knob (or adjust EG Int and Decay), you will hear the typical "meow-ing" sound typical of analog synthesizers. If the resonance is raised, the sound may be distorted depending on the cutoff frequency or on the pitch that you play. 4. Pattern mode 1/4. . . 8 Set the delay time. If you have selected Tempo Delay as the effect type, this parameter will let you set the tempo in terms of sixteen different multiples of the step: 1/4, 1/3, 1/2, 2/3, 3/4, 1, 1. 33, 1. 5, 2, 2. 5, 3, 4, 5, 6, 7, or 8. Depending on the tempo setting, it may be impossible to set the delay time. In such cases, set the delay time to half the desired value. EG Int (EG intensity) –100. . . 0. . . 100 Specify the depth and direction of the effect that the EG (envelope generator) will have on the cutoff frequency. The EG will start when trigger-on occurs (the instant you play the keyboard). If the gate time length of a step extends beyond the point at which the next step is sounded, the EG will not be re-triggered for the next step. Chorus/Flanger settings Set the Type Select button to Chorus/Flanger, and adjust the chorus/flanger. Chorus creates minute differences in the pitch to produce an ensemble effect, and Flanger adds a "swooshing" modulation to the sound. • Depth (chorus/flanger depth) 0. . . 100 Decay 0 msec . . . [. . . ] If you attempt to record additional events, the "memory full" message will appear immediately. Either use Clear Event to delete unwanted events from a song, or record blank data to clear the memory. Restoring the factory set data The pattern and song data with which the EA-1 is shipped from the factory is referred to as the "preloaded data, " and you can restore this preloaded data back into the memory of the EA-1. When you do this, the patterns you created and the songs which use these patterns will be erased, and replaced by the preloaded data. If you wish to keep the patterns and songs you created, you must save the data on a data filer etc. [. . . ]
