Sounds
4. PANPOT: determines the sound’s position in the Stereo Panorama (between the
internal Speakers or the Stereo outputs Left/Right).
Value range: -32… 0… +32.
“0” corresponds to the centre, -32 all to the left, +32 all to the right.
5. TRANSPOSE: determines the transposition of the Sound with respect to the
note selected in the active layer.
Value range: -88… 0… +88.
This function is very important when programming Drumkits, or when
programming a sound to cover a particular extension of the keyboard
using the EXPAND option.
Why is transpose so important?
All the sample headers incorporated in the percussion ROM Sounds have an “ideal”
sampling frequency. To reproduce the correct sound, therefore, you must apply a
frequency “correction”, or allowance, so that the sound plays correctly when you strike
the relative note. The correction is achieved with the Transpose parameter.
Drumkit programming and the Transpose parameter
If you consult the PERCUSSION SAMPLE Table in the Appendix, you will see that all
percussion instrument sounds provide the correct timbre if they play at the frequency
corresponding to a specific note on the keyboard.
Therefore, the idea is to transpose a percussion sound to its correct “sample note” after
assigning it to a particular keynote.
Example
Starting with the Drumkit DKJazz, let’s suppose that you want the sound BRUSH to play
at note E2 in place of the programmed SDBRUSH2. From the Percussion Sample table,
you can see that the sample note for BRUSH corresponds to C5.
Select CATCHNOTE and press note E2
1
.
Select the SOUND parameter and rotate the DIAL (clockwise) until BRUSH is selected.
Now the sound must be transposed to a value that corresponds to the “distance” in
semitones from E2 to the sample note C5.
Select the TRANSPOSE parameter and simply count how many semitones there are
from the keynote E2 to the sample note C5. The value to specify, therefore, is 32.
NB. In cases where you want to assign an instrument to a note that is higher than the
corresponding sample note, the Transpose value should be negative (count the semitone
distance from the higher note down to C5 and specify a negative value).
6. TUNE: fine tunes the current transpose value.
Value range: –64... 0… +64
Each step corresponds to 1/64th of a semitone.
We suggest the following uses for Tune:
1. To fine tune an otherwise too precise transpose value assigned to drumkit
instruments, in order to give a more natural effect;
NOTE 1:
WX2 = lowest E,
WX400 = 2nd lowest E.
