Note
The parameters of Filter2 are only Frequency and Resonance.
Moreover, ADSR does not work to Filter2.

Type	Please select the kind of filter.
	LPF(LOW PASS): This filter cuts out the high frequencies and passes the low frequencies. BPF(BAND PASS): The filter passes the specific frequencies and cuts out the other frequencies. HPF(HIGH PASS): This filter cuts out the low frequencies and passes the high frequencies. EQL(Equalizer Low): Low sound is boost and cut. (This parameter is not in MPC2500) EQH(Equalizer High): High sound is boost and cut. (This parameter is not in MPC2500) LNK(Filter2): The always same setting as a filter 1 is applied.
Frequency	Please set the cut off frequency. (0-100) When TYPE are EQL and EQH. Boost/Cut (-100 to +100)
Resonance	If you set the resonance value at a larger value, the frequencies set in the "Frequency" column will be boosted more. (0-100)
Vel.Depth	The value of Velocity is added to ADSR Depth. Example Vel.Depth:100 1-100 is added to ADSR Depth by Velocity. Vel.Depth:50 1-50 is added to ADSR Depth by Velocity. When Cutoff wants to change by Velocity (ADSR is not used), please set the value of ADSR as follows. In the following example, it changes Frequency 50-100 by Velocity.
Aftertouch	The value of the pressure of a pad is added to Frequency. Example Aftertouch: +100 1-100 is added to Frequency by the pressure. Aftertouch: -50 -1 to -50 is added to Frequency by the pressure.
A(Attack)	Time until reaching the value of NOTO ON to DPTH is set.
D(Decay)	Time until it reaches a value set by "Sustain" from the value of "DPTH" which reached by "Attack" is set.
S(Sustain)	The end point of Decay is set.
R(Release)	Time until it reaches a value of "FRQ" from NOTE OFF is set. (Release cannot be set when PLAY MODE is ONE SHOT)
ADSR Depth	Quantity whose effect of ADSR to a filter is effective. If the value here is 0, ADSR will not work.

Cutoff frequency of Filter changes, as shown in the following figure.

The value of ADSR is added to the value of Frequency of a Filter parameter.
