MZ-2000 MIDI Implementation

4.Threshold

Threshold input level for the compressor/limiter effect. Though the compressor and limiter use the same algorithm, the items in the effect Preset List named Limiter are optimized for the limiter by setting the actual level for the threshold value at a high level.

5.Depth

Compressor/limiter compression factor. A large value results in a low signal level while the compressor/limiter function is working, so correction is required depending on the Level setting.

6.Level Output level

Operation

Though the Compressor/Limiter is a two-channel, left-right input effector, input signal level detect is performed after the left and right signals are mixed. Operational principles and parameter operations are identical to those for Compressor/Limiter. Parameter operations are identical for the left and right channels.

Operation

This effector change the input signal of the attach part to a slow attack. It is used for guitar tones and solo synthesizer violin play.

Whenever the input signal drops below a preset level, the gate closes and the output signal is muted. With the next input signal, the gate opens slowly, so the attack is eliminated. To delay the attack, temporarily mute the input signal.

1.Bypass

Effector function enable/disable. Selecting bypass causes the input signal to be output as-is.

2.Threshold

Slow attach threshold input level. The output signal is muted when the input level is below this setting. Setting a value that is too high causes the tone to be cut too quickly. Setting a value that is too low causes incomplete muting and makes it impossible to obtain the slow attack effect, and makes it difficult to play with little interval between notes. When setting a value, you need to take such factors as the attenuation characteristics of the inputtone and phrasing into consideration.ÅB

3.AttackSignal rise attack time. The larger the value, the slower the rise.4.Release

Time from the point the input signal drops below the Threshold level until the signal is muted.
