Volume Indicator with Sound For MT-4

Hi Frineds,

I have been looking for a long time for an indicator that will show the volume in digital form and it will sound based on the pre-set level. It may be greater or lower than pre-set level. An example is given below:


Pv-65 (present Volume)

Lv-30 (Previous Volume)

PLv- 14 (Volume before the previous Volume)


If the Pv(Present Volume) is greater or less than the set level, it will produce sound. Suppose If the the Pv is 20 (Pv=20) that is lower than the set level (25), it will sound.

Hope to get the response. Thanks in Advance
