Please note this from the firmware update page:
After updating the DDJ-1000SRT firmware to ver.1.02, Sampler Master Volume level of Serato DJ Pro does not sync with the SAMPLER VOL knob on the DDJ-1000SRT. If you find that the DDJ-1000SRT Sampler volume level is not appropriate, even when turning the SAMPLER VOL knob, please adjust the Sampler Master Volume level in Serato DJ Pro on your PC/Mac.

ver. 1.02 Update
- The BPM values that are shown on the DDJ-1000SRT Beat FX display and in Serato DJ Pro virtual deck, did not sync.
- Sampler sound did not come out from the headphone output when the Sampler Cue button was pressed while the Sampler volume level was at its lowest.
The MIDI message for the Sampler VOL knob has been changed in line with this fix.
