When track is paused the audio is skipping, what's going on?
Each deck on the SDJ-4000 can play in two different modes: VINYL mode ON or OFF. Use the VINYL button under each JOGWHEEL to switch between modes. When button is illuminated the deck, VINYL mode is ON, if it is not VINYL mode is OFF. Both modes will allow you to pitch bend (temporarily slow down or speed up the track) with the JOGWHEEL but there are a couple key differences.
With "VINYL" mode ON, the playback will pause when you touch the top of the platter, this is to emulate a vinyl record on a turntable. This also allows for "Scratching" via the JOGWHEELS. (Touching the top of the platter will do nothing when VINYL mode is OFF)
If VINYL mode is turned OFF, when the track is PAUSED you will hear the audio from the exact location of that deck's playhead repeatedly on loop, allowing you to easily find a downbeat for cueing by moving the JOGWHEEL forward or backward to move the playhead. (You will hear nothing when the deck is paused in VINYL mode.)
What is BPM MODE?
There are three different BPM modes specific to each deck that will alter the BPM info for whatever track is loaded. AUTOBPM is set in V-CASE or by the units onboard processor. ID3 mode takes the BPM value from the files ID3 tag. MANUAL mode allows the user to manually adjust the tracks BPM info using the BEAT GRID tools in the MAIN FX section.
