the pitch, the playback lags behind, and when you return the pitch to normal, the playback
snaps back to the present—which 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 fills 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 K2661 plays buffered data from the input source, which
enables the K2661 to “play ahead” 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. Here’s 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 LFO1’s 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.
Now at the Mod Wheel extremes, you will hear only one layer or the other, while in the middle,
you will hear a combination of the pitch-modulated signal and the unmodulated signal. By
experimenting with FUNs, you can get more precise crossfades.
The program 744 LM Synth Sliders includes this kind of crossfade, tied to the Pitch Wheel, to
implement a 3-layer crossfade. Moving the Pitch Wheel up fades to a layer which is bending the
pitch up. The surprise is that moving the Pitch Wheel down bends the pitch down, then up
again, crossfading to a layer that is playing back in reverse! Yes, reverse playback works with
Live mode: on the KEYMAP page, set PlayBackMode to Rvrs.
