User manual KORG GA-40

[. . . ] Note: Make sure that UPPER and LOWER DRAWBAR SELECT are set to "PRESET". The Programs in the GA-40 are `organ'-ized via Vertical Banking. For instance, pressing key #8, and then cycling through the Banks, shows off Programs that mimic a tone wheel organ's "Church" presets. To select an EX Mode Program, press the EX MODE key, and then select Programs as above. [. . . ] Type 2 models the classic British Rock sound of a tonewheel organ run through both a rotary speaker and a tube guitar amplifier. For a couple examples of the Type 2 sound, try Presets A7 ­ DS Balls!, B7 ­ Turkish, C7 - SmokeInJapan, G7 ­ BC RockSolo, or F3 ­ Gimme Some. A word on Expression / Overdrive. . . Notice, as you play through some of the Programs and work the OXP-1 pedal that Expression and Overdrive coincide: the sound gets grittier as it gets louder!If you don't have an OXP-1 pedal connected, the EXPRESSION/OVERDRIVE knob duplicates this function. Just be sure to check the setting of this knob ­ if it is up all the way, your Presets may sound "dirtier" than desired. Conversely, if the knob is set too low, you won't be getting the extra "drive" that many sounds require. Understanding the Drawbar Select switches: History: Control of two separate tone generators The classic B-3 has an octave of reverse-colored keys to the left of each of its two manuals. Pressing one of these keys selects a Preset; except Bb, which engages Drawbar set #1, and B, which engages Drawbar set #2. The lowest C cleared any selected keys/presets. · The key in the UPPER row determines the status of the Upper tone generator; the key in the LOWER row determines the status of the Lower tone generator. Each tone generator is independently switched to one of three choices: Preset, Drawbar Set #1, or Drawbar Set #2. Note that the physical layout mimics the real B3 ­ the preset is to the left and the live drawbar selects are to the right!This makes the GA-40 immediately comfortable to the experienced B3 player! ! · In EX Mode, the LOWER Drawbar Select keys are dark: in Extended Drawbar Mode, both of the tone generators are used for additional harmonics and percussion, and the two sets of drawbars are working in tandem. Version 2 adds a three-drawbar tone source for the lower sound, controlled from within the Edit Mode only. These edits will not be retained unless they are written to the Program. ! Writing a Program 1. Note the speaker icon: when it is next to the left Bank/Program#, it allows you to hear the edited Program in the buffer. Press the [>] CURSOR key once, and the speaker icon moves to the right Bank/Program #. This allows you to audition the destination Program before you destructively write over it. Use the [+] or [-] keys if you wish to find another destination. Press the WRITE/ENTER key twice to execute the Write operation. 3. Restoring Factory Preload data 1. 2. Hold down keys #2 and #7 while turning on the power (power switch located on the back of the GA-40). The display will prompt "Load Factory Data?" press the WRITE/ENTER key to complete the operation. 4 CX3 EasyStart Using another keyboard as the `Lower Manual' . . . Taking advantage of the two independent tone generators: 1. 3. Using a short MIDI cable, connect the MIDI Out of any MIDI keyboard/controller to the MIDI In of the GA-40 and set its MIDI channel to Ch. The parameter for the MIDI Channel of the GA-40's Lower tone generator defaults to Ch 2, but it can be set to any channel: Press GLOBAL, then press key #4, and CURSOR [>] four times until the display reads "MIDI Lower Rx ch:". If you call up a Program that has an active Split (SPLIT Key is lit), press the SPLIT Key once to turn it off. [. . . ] Drawbar set #1 is governing the levels of the standard nine harmonics of a traditional tonewheel organ, while Drawbar set #2 controls the extended harmonics of EX Mode. This included four additional tone generator harmonics, and four additional percussion tone harmonics. · The first four drawbars of set #2 add additional, higher harmonics to the basic tone-generating system. There are four Presets for these extended harmonics. [. . . ]
