The Multi-Samples; Loading A Multi-Sample That Is To Be Modified - KETRON SD1 User Manual

The advantage of using the loop lies in the possibility to save a lot of RAM space. In fact all electronic keyboards have been exploiting samples
with loops for years. It is not easy to find the loop and it takes a few attempts to create an audio repetition without hearing digital noises or
oscillations of the pitch and the amplitude. Another use of the loop relates to drum grooves. Once you have sampled just a few beats you can
repeat the two beats endlessly. In this case it is easier to find the loop as each groove has a starting point and a precise ending point.
Once a sound has been loaded or sampled, to access the loop editing function, from the initial page of the Sampler MSP menu, press F6 View.
The window that appears after a few seconds of processing shows a graph of the wave shape and a number of parameters to the left. Use the
zoom function of the wave shape to make it easier to find the loop points.
F1 Start: The value that can be modified using the VALUE +/- push buttons is used to accurately establish the starting point of the sam-
ple indicated with the S line on the graph. If it is impossible to enter a value above zero ensure that the starting point of the
loop, established by F2 Loop, is greater than the value of F1 Start.
F2 Loop: The value that can be modified using the VALUE +/- push buttons indicates the starting point of the loop and refers to line L on
the wave shape.
F3 End: The value that can be modified using the VALUE +/- push buttons indicates the ending point of the loop and always coincides
with the end point of the sample, referred to line E on the wave shape.
F4 Zoom:
This is used to enlarge the wave shape picture by up to 1600 times to make it easier to find the starting point of the loop. To
modify the zoom value, proportional to the last point modified, press F4 Zoom and use the VALUE +/- push button. When F4
Zoom is set on Envelope, the wave shape is displayed right across the display.
F5 Escape: This returns to the initial page of the Sampler MSP menu.

THE MULTI-SAMPLES

MSP stands for Multi-sample, namely the assignment of a number of samples across the keyboard, with their own pitch and volume parameters,
in order to create one single audio file that is much more complex compared to a single Wave file. When a Multi-sample is created or modified
the whole RAM contents are cancelled. The F4 MSP Edit function is used to modify a Multi-sample that already exists, cancelling the RAM con-
tents in use at the time, whereas the F5 MSP New function creates a Multi-sample from zero.

LOADING A MULTI-SAMPLE THAT IS TO BE MODIFIED

From the initial page of the Sampler MSP menu access the editing function of the Multi-sample by pressing F4 MSP Edit, which is used to load
a Multi-sample that already exists in Hard Disk or Floppy Disk, with the usual disk selection procedures using the PAGE +/- push buttons. Select
the files using the VALUE +/- push buttons and confirm the choice using F10 Select. The functions available are the following:
F1 Dir: This shows the list of MSP files stored in the Folder in use at the time.
F2 Load: This is used to load one or a number of MSP files selected in RAM.
F5 Escape: This shows the initial page of the Sampler MSP menu.
F10: Together with the VALUE +/- push buttons it is used to select one or a number of files to be loaded.
Once the Multi-sample has been loaded, the SD1 automatically opens the MSP Edit page that is identical to the F5 MSP New function.
