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 de-
tect 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. Attack
Signal 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.
