✩Control Parameter
The following parameters specify data related to parameters controlled by CC.

000A | Val | 7 | 00H | - 7FH Current value of this parameter |
000B | Min | 7 | 00H | - 7FH Minimum value of parameter sent to Fx |
000C | Max | 7 | 00H | - 7FH Maximum value of parameter sent to Fx |
The above three parameters determine the actual value of the parameter sent to the Fx. Change is performed in a linear manner to one of 127 levels between the Min and Max values, in accordance with the current value.
The value actually sent is the value of V, as calculated by the following.
V = Min + (Max - Min) * Val/127
When Max = 1 and Min = 0:
If Val < 64, V = 0
If Val >= 64, V = 1
The current valu alters the Fx parameter vlue assigned when the Fx macro is initially imported, so the tone can be changed by specifying the same Fx Num.
The Val value is the actual received control change value, which is changed within the range of 0 to 127. 0 is the Min setting and 127 is the Max setting. Values between these extremes are obtained by linear inter- polation, and those values are provided as effector parameter values.
*Note
Even when parameters are sent immediately following the Fx selection operation, the values may not be reflected immediately because it takes some time to perform Fx switching.
All of this means that when sending a Val parameter, an interval of at least 100 msec must be allowed after sending the Num segment Fx selection parameter connected with the Val parameter.
000D DefaultVal 700H - 7FH Default value
This value can be set only. It is not used internally by the MZ-2000
*Note
d1[1] is the parameter number, which is the serial number within the parameter Fx macro. Two parameters can be programmed per Fx Macro, so the range is 0 or 1.
4.11.4 Effect Macro Parameter Set Bulk Dump
The Effect Macro Parameter Set can be sent and received using bulk dump. There are two proto- cols,
The following shows the section that applies to effects only.

The volume of data that follows the above is very large, so it is not included here. This data can be looked up by sending HDR and BDR.
4.11.5 Control Using the Val Control Change Message
The Val parameter itself can be changed using a control change message. This makes it possible to perform chained control of the prescribed parameters of the effect linked to this parameter.
Channel
The MIDI channel of this message is compared with the MIDI Global channel, and the operation is performed when the channels matched.
Number
The effect macro parameter can be controlled using the prescribed control change numbers listed below.
