Resampling and Time Compression / Expansion 
 
The Resample routine is found under [EDIT]: [TRIM/LOOP]: [COMMAND key]: RESMPL.  This 
page allows you to (1) adjust the length (longer or shorter) of the playback time (Time 
Stretch) without affecting the sample’s pitch or (2) to adjust the Pitch directly (Pitch 
Conversion) without effecting the length. A time Stretch of 100% is no change. 50% plays 
in half the time, 200% takes twice as long to play, 300% takes 3 times as long, 400% 4 times 
as long, etc. Beyond a certain point it becomes an unusal effect- but that’s just fine. You 
can weight the results toward rhythmic accuracy or sound quality. You can time stretch 
a specific number of samples or set the value via the convenient % scale. You can 
calculate any exact time or tempo you need. An interesting thing to note is that you can 
audition how the Time Compression/Expansion or Pitch Conversion will sound before you 
execute it. This is accomplished by simply pushing and holding the (TmStretch) knob. You 
can, of course, change the Pitch without changing the tempo.  
 
The RESAMPLE routine is found under the COMMAND key when pressed from [EDIT] 
mode: [TRIM/LOOP] function. Executing this routine actually re-writes the sample data. 
 
Resampling Audio through the Effects 
 
A very useful trick on the A3000 is re-sampling data through the Effect processors. This 
connection is handled internally by the A3000 operating system. Prepare the sample and 
apply the effects PLAY mode. You can utilize any or all the effect processors in any 
manner you wish.  1/2/3/ signifies the 3 processors in parallel. 1Æ2/3 signifies 1 and 2 in 
series while 3 remains in parallel. 1Æ2Æ3 is all 3 processors in series. When ready, navigate 
to the [RECORD]: [SETUP]: [Rec Data] page.  
 
Set the INPUT parameter to ST OUT (Stereo Out). This connects the A3000 Stereo output 
(post Effects) to the record input via internal routing. You can use either triggered record 
or manual record as your method; the A3000 will resample the data and create a new 
sample. You can even resample at a lower or higher sample rate, as necessary.  
(Notice that nothing can be set on the [RECORD] mode: [EFFECT] function page –  the 
RecEfSw (Record Effect Switch) is forced to off – this page is used for original recordings, 
only, not re-samples). 
 
Building Custom Volumes 
 
Assembling custom volumes from programs found in other volumes is a simple 
procedure.  You must first load individual Programs from different volumes.  Then, after 
you have the programs you want, you simply create a new Volume and load those 
programs into your new custom volume. The procedure to load individual Programs into 
the A3000 is:   
 
1.  Navigate to the [DISK]: [DISK]: [Disk] page and select the appropriate source disk- 
SCSI or floppy. 
2.  Next navigate to the [DISK]: [VOLUME]: [Volume] page and select the appropriate 
Volume that contains your favorite Program. 
3.  Next navigate to the [DISK]: [PROGRAM]: [PgmLoad] page and select your favorite 
Program from a listing of all Programs in the selected Volume. 
4.  Now instead of executing the load, press the [COMMAND] key. Here you re-route the 
selected Program to any of the 128 locations.
