How can a drum loop be synced to the sequencer and/or external MIDI clock?
If you have a K2600/2661 or a K2500 with v4 or later of the operating system, you will have a Control Source called Tempo. This Control Source uses the K2's own internal clock or an external MIDI clock (depending on the setting of the 'Clock' parameter on the SongMode:MISC page - more info below) as a modulation source.
One possible application for the Tempo control source would be syncing a sampled drum loop to sequencer clock. Here is the basic procedure:
EditProg:PITCH <>Layer:1/1 Coarse:0ST Src1 :Tempo Fine :0ct Depth :7200ct FineHz:0.00Hz Src2 :OFF KeyTrk:0ct/key DptCtl:OFF VelTrk:0ct MinDpt:0ct MaxDpt:0ct <more ALG LAYER KEYMAP PITCH more>
EditProg:PITCH <>Layer:1/1 Coarse:-60ST Src1 :Tempo Fine :0ct Depth :7200ct FineHz:0.00Hz Src2 :OFF KeyTrk:0ct/key DptCtl:OFF VelTrk:0ct MinDpt:0ct MaxDpt:0ct <more ALG LAYER KEYMAP PITCH more>
** As an explanation, the Depth of 7200ct is six octaves, corresponding to six doublings of tempo from 3.75BPM to 240BPM (the system limits).
| TIP: Internal vs External Clock Sync Options
When syncing to its own internal clock (Clock:Int)...
...the master clock tempo (bpm) is set by the 'Tempo' field on the SongMode:MAIN page.
When syncing to an external clock (Clock:Ext), the clock source is derived from the MIDI Clock signal being fed into the K2's MIDI IN port.
