Seq uencing with the XP-50 and External MIDI Sound Sources (continued).
3) CURSOR RIGHT to Local and use the VALUE DIAL to select “OFF.”
4) Press SYSTEM so it is not lit to return to the previous display.
NOTE: Remember to turn Local Control back on when using the XP-50’s internal sound generator.
Controlling the Level of an External Sound Source while Sequencing
In certain applications, you may wish to sequence the information for the internal parts and not hear an external
sound source (assigned to the same MIDI channel) while performing. The easy way to achieve this would be to
switch MIDI Receive on the external sound source to Off for this particular MIDI channel. If this is not possible,
you can set the C1 slider to control the volume of the external source without affecting the volume of the XP-50’s
internal sounds (your external sound source must respond to MIDI volume messages for this to work):
1) Press SYSTEM.
2) Press 3/11 (CONTROL).
3) Use the CURSOR UP/DOWN buttons to select the C1 Assign page.
4) Use the VALUE DIAL to select “CC07: Volume.” This assigns C1 to be a volume slider.
5) Use the CURSOR RIGHT button to select “Output.”
6) Use the VALUE DIAL to select “MIDI.”
7) Press EXIT. If you move the C1 slider down now, it will turn the external sound source down and not affect
the internal XP-50 sounds.
Simultaneous Notes Creating Delay
It is possible to create too many notes at one time for the sequencer to play. This may occur when using the
quantize function of the XP-50 in excess. This can cause the timing to sound slow when several notes are
triggered simultaneously. The shift clock function can be used to solve this problem by shifting a few tracks
forward or backward by one or two clock pulses. Use this example to shift a drum track on MIDI channel 10
forward by 2 clock beats:
1) Press SEQUENCER.
2) Press EDIT so it is lit.
3) Press 1/9 (TRK EDIT).
4) Use the VALUE DIAL to select “11: SHIFT.”
5) CURSOR to Target and use the VALUE DIAL to select “TRK ALL.”
6) CURSOR to Measure and use the VALUE DIAL to select “1 for ALL.”
7) CURSOR to Bias and use the VALUE DIAL to select “-2.”
8) CURSOR to Status and use the VALUE DIAL to select “ALL.”
9) CURSOR to Ch and use the VALUE DIAL to select “10.”
10) Press ENTER. The screen will briefly display ‘EXECUTING’ and then return to the edit screen.
11) Press EXIT.
Displaying and Changing the Length of the Internal Song
The XP-50 can calculate the song length and adjust the tempo map to fit a desired song length. This is useful if
you need a piece of music to fit into a specific time period:
1) Press SEQUENCER.
2) Press EDIT so it is lit.
3) Press 7/15 (SEQ UTILITY).
4) CURSOR down to TIME FIT. The first set of hours, minutes, and seconds is the current song length, and the
second set allows you to enter your desired song length.
5) Use the CURSOR LEFT/RIGHT buttons and the VALUE DIAL to set the desired song length, then press
ENTER. The tempo map will be altered to fit your new song length.
Loading and Playing a Song Chain
You can create a chain of songs on a disk for sequential playback by the XP-50. Use the following procedure to
load and play a song chain that you have already created on a disk:
1) Power on the XP-50, then insert the disk containing the Song Chain.
2) Press CHAIN PLAY.
