E-38The Synthesizer Mode of this keyboard provides the toolsfor creating your own original tones. Simply select one of thebuilt-in tones and change its parameters to create your ownoriginal sound. You can even store your sounds in memoryand select it using the same procedure as that used to select apreset tone.Synthesizer Mode FunctionsThe following describes how to use each of the functionsavailable in the Synthesizer Mode.Synthesizer Mode ParametersThe preset tones that are built into this keyboard consist of anumber of parameters. To create a user tone, you first recall aGeneral MIDI tone (100 to 227) or a preset tone (000 to 099)and then change its parameters to change it to your own tone.Note that drum set tones (228 through 237) cannot be usedas the basis of a user tone.The illustration below shows the parameters that make upthe preset tones and what each parameter does. As can beseen in the illustration, these parameters can be divided intofour groups, each of which is described in detail below.❚ NOTE• Synthesizer Mode operations affect the tone selected for Chan-nel 1.Synthesizer Mode703A-E-040AVolume CharacteristicParametersAttack TimeRelease TimeResonanceCutoff FrequencyTone Pitch ParametersVibrato TypeVibrato DelayVibrato DepthVibrato RateOctave ShiftTone CharacteristicSetting ParametersLevelTouch SenseReverb SendChorus SendDSP LineDSP TypeDSP ParameterOutputTone CharacteristicWaveformTone Setting(1) Tone Characteristic Waveform Tone SettingSpecifies which of the preset tones should be used as the orig-inal tone.(2) Volume Characteristic ParametersThese parameters control how the tone changes over time,from when the keyboard key is pressed until the tone de-cays. You can specify changes in volume and sound charac-teristics. Attack timeThis is the rate or time it takes for the tone to reach its high-est volume level. You can specify a fast rate, where the tonereaches its highest volume level immediately, a slow ratewhere it gradually rises, or something in between. Release timeThis is the rate or time it takes for the tone volume to fall tozero. You can specify a release that ranges from a sudden fallto zero, to one that gradually falls to zero. Cutoff FrequencyThe cutoff frequency is a parameter for adjusting timbre bycutting any frequency that is higher than a specific frequen-cy. A larger cutoff frequency produces a brighter (harder) tim-bre, while a smaller frequency produces a darker (softer) tim-bre.TimeNote endsKey pressedA RKey releasedEnvelopeA: Attack timeR: Release timeLevelCutoff frequencyFrequency
