Sampling and Sample Editing
Live Mode
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.
Arpeggiator
You can also do controlled pitch shifting on incoming audio using the arpeggiator. By constantly
sending new note starts, it is possible to bend the pitch without losing the tempo of the
incoming signal.
It can work in both directions, although when you are shifting signals up in pitch, youÕre
ÒborrowingÓ the audio from a few seconds previous.
1. Go to Setup mode and select 97 Control Setup.
2. Press Edit, and on the CH/PRG page, set the program to 749 LiveMode Default.
3. With the program highlighted, press Edit and go to the AMPENV page.
4. To make the crossfading less choppy, you want short attack and release segments: set Att1
5. Press Exit and save the program to some new ID.
6. Now go to the ARPEG page and set the Active parameter to On.
7. Set the Duration parameter to 99%.
8. For this example, set Order to Simultaneous and Beats to 1/32.
9. Tempo should already be 120.
Now play C 4 and youÕll hear the live signal at the correct pitch. Play G 3 and you will hear the
signal pitched down a fourth. You can use the ribbon or similar controller to bend the pitch
smoothly. Going above unity pitch will cause a jump back into the past.
Experiment with the Tempo, the Beats setting, the Duration value, and the AMPENV
parameters to get useful variations on the program. Remember that because we set the Order to
Simultaneous, you can play several notes at once. And Þnally, try setting Glissando to On.
Sustained Notes and Loops
If the incoming signal is a single, sustained pitch, like a saxophone note, then you can consider
the Live mode keymap to be playing a normal, looped sound. In this case, the fact that an
upward bend jumps back a few seconds is no big deal because the sound hasnÕt changed much
during that time.
With this technique, melodies or chords can be played based on a segment of a live performance.
Keep in mind that, unless your incoming signal is a C, notes and chords played on the K2600
keyboard will be transposed relative to the incoming pitch. Also remember that a rhythm
pitched an octave down will play at half the speed, while one pitched an octave up will play
twice as fast. Fifths produce a 3-against-2 pattern. To keep some sort of relative sync with the
14-44
to 0.06/100% and Rel1 to 0.10/0%.
