DJM 2000 INST FX (Firmware version 2.01) - VOLUME Level Issue

          System: Windows XP SP3

          Rekordbox 1.5

          No CDJs connected

     Test 1:  Laptop connected to DJM via USB port

Comments:

1.  Music track on channel 1

2.  FX effect assigned to channel 2

3.  Engage or press the JET Inst FX and adjust the Parameter (volume) and Filter to get the

     desired 'audible' effect from the speaker.

4.  Now, press the Noise button without changing the previous settings (above) suddenly, the volume

     leaps exponentially loud.

          Note:    There is no volume change from 'JET to 'HPF' or 'JET to LPF' or 'JET to CRUSH' nor 'JET to ZIP'

If this is a bug, it should be corrected in the next firmware update.

 Question:    What am I doing wrong?   Is it just my unit that's  defective?  I just bought this 2 weeks ago.

 Appreciate any help.
