For starters, you can simply hook up a CD player to one of the K2600Õs sampling inputs, get a
bunch of your favorite CDs, and start fooling around. (A turntable works well too.) Here are
some ideas for going further:
Pitch Changing
Unlike an analog synthesizer, the K2600 makes it possible to alter the pitch of the incoming
signal in real time. But the K2600 is not a conventional pitch shifter, so if you are used to
working with such a device you will have to alter your thinking a little.
For example, when you bend the pitch down from the unity pitch (C 4), using a VAST function,
it slows the playback of the incoming signal, but it doesnÕt change the rate at which the signal is
coming inÑyour CD is still spinning, and putting out a constant audio signal. So as you lower
the pitch, the playback lags behind, and when you return the pitch to normal, the playback
snaps back to the presentÑwhich means some of your audio literally disappears into the ether.
If you bend the pitch down and hold it there for a while, eventually the buffer Þlls up and
updates itself, and you will hear it snap forward in time, although the data playing will continue
to be slowed down. Again, some of the audio disappears.
When you bend pitch upward, the K2600 plays buffered data from the input source, which
enables the K2600 to Òplay aheadÓ of the input. You may hear some of the input data repeat
when you release the pitch bend.
These details aside, all kinds of wonderful pitch effects are achievable. HereÕs an example.
1. Start with Program 749 LiveMode Default.
2. Go to the PITCH page.
3. Assign LFO1 to Src1, with a depth of -200ct.
4. In order to keep the playback from constantly crossing above unity, set the Coarse
parameter to -2ST.
Or try these settings:
Src1 MWheel
Depth -1200c
Src2 LFO1 (On the LFO page, set LFO1Õs MnRate to .50Hz, MxRate to 20.00, and
RateCt to Data.)
DptCtl MWheel
MinDpt 0ct
MaxDpt 1200ct
Sometimes the LIve-mode audio will sound discontinuous as LFOs and the buffers get out of
sync. You might be able to smooth out the rough spots by making another layer with no pitch
alterations, and crossfading between the layers:
1. Duplicate the layer.
2. Clear all the settings on the PITCH page.
3. Go to the OUTPUT page and set Crossfade to MWhl on both layers.
4. On layer 1, set XFadeSense to Rvrs; on layer 2, set XFadeSense to Norm.
