Level1Ð3 (Amplifier Envelope Level

1Ð3)

These parameters specify the volume at each point.

You can set the three points Level1Ð3.

Range: 0Ð127

Higher settings will also raise the volume.

* The front panel [S] (Sustain Level) corresponds to Level3.

Velo Time1 (Amplifier Envelope

Velocity Time 1 Sensitivity)

Specifies how Time1 will be affected by the strength of

your playing on the external MIDI keyboard.

Range: -100Ð+100

With positive (+) settings, Time1 will become faster as

you play the keyboard more strongly. With negative (-)

settings, Time1 will become slower as you play the

keyboard more strongly.

* It is not possible to control this by varying the force with

which you press the keyboard pads.

By setting Velocity Time 1 Sensitivity to positive (+)

settings you can create volume changes that will be

appropriate for strings-type sounds. The volume

attack will be gradual for softly-played notes, and

faster for strongly-played notes.

Velo Time4 (Amplifier Envelope

Velocity Time 4 Sensitivity)

Specifies how Time 4 will be affected by the speed at

which you release the external MIDI keyboard.

Range: -100Ð+100

With positive (+) settings, Time4 will become faster as

you release the keyboard pads more quickly. With

negative (-) settings, Time4 will become slower as you

release the keyboard more quickly.

* It is not possible to control this by varying the speed with

which you release the keyboard pads.

Time KF (Amplifier Envelope Time Key

Follow)

This parameter specifies how the amplifier envelope

times (Time2/3/4) will be affected by the keyboard

pad location.

Relative to the envelope of the C4 note, higher settings

of this parameter will cause greater change in enve-

lope times.

Range: -100Ð+100

With positive (+) settings, envelope times will become

shorter as you play higher notes. With negative (-) set-

tings, envelope times will become longer as you play

higher notes.

●●●●●●●●●●●●●●●●●●●●●●●●●●●●●●●●●●●●●●●●●●●●●●●●●●●●●●●●●●●●●●●●●●●●●●●●●●●●●●●●●●●●●●●●●●●●●●●●●●●●

On instruments such as a piano, the volume decays

more rapidly for higher notes. This can be simulated

by setting Time Key Follow to positive (+) settings.

Delay Start

For example, by setting Level1 to Ò0Ó and adjusting

Time1 [A] appropriately, you can create envelopes in

which the sound does not begin until a certain time

after the key is pressed.

Applying Cyclic Changes to

the Sound (LFO)

The LFO (Low Frequency Oscillator) applies cyclic

change to the sound. The MC-505 has two LFOs

(LFO1/LFO2), and each of these can be used to modi-

fy the pitch, cutoff frequency or volume of each tone to

create effects such as vibrato, wah and tremolo. Since

both LFOs have the same parameters, the following

explanation will cover both of them.

Selecting the Waveform That

Will Modulate the Sound

(LFO1 Waveform)

Select the output waveform for LFO1. The sound will be

modulated in the same shape as the selected waveform.

1. Press [WAVEFORM] several times to select

the waveform.

When the waveform at the left is selected, the indica-

tor will light. When the waveform at the right is select-

ed, the indicator will begin blinking.
