6.3 LOADING NEW SAMPLES INTO THE DPM V3
The DPM V3 oscillators play back sampled sounds that were recorded, digitized, and
stored in ROM (permanent memory) chips by Peavey for use in the DPM V3.
However, it also can include up to 1 Megabyte of battery-backed up RAM, which
allows you to load in your own samples via MIDI. This takes advantage of a part of
the MIDI specification, the Sample Dump Standard (SDS), which specifies a universal
way to exchange samples between those instruments whose specifications conform to
the SDS. Unfortunately, not all samplers are SDS-compatible and many use their own
methods of data transfer. Furthermore, for CD-quality fidelity the DPM V3 is a 16-bit
machine; it therefore requires that samples be sent as 16-bit data. Check your
sampler's manual to see if it can transfer samples according to the SDS 16-bit stan-
dard. If not, you will not be able to transfer samples directly between the sampler and
DPM V3. we
Fortunately, there is a convenient workaround. Sample-editing software programs (such
as Sound Designer and Alchemy for the Macintosh, Avalon and Genwave for the
Atari, Sample Wrench for the Amiga, and Samplevision from Turtle Beach Systems) ex-
ist for virtually all popular computers. These programs can transfer samples between
the computer and those samplers supported by the program, regardless of whether or
not they support SDS. The program should also be able to translate samples that use
incompatible formats. Therefore, a non-SDS sample can be brought into the program,
translated, and sent out over MIDI as an SDS sample to the DPM V3, thus opening up
a potentially huge library of samples.
There are two main ways to transfer samples to and from the DPM V3:
« Sending samples to the DPM V3, such as from a sample-editing program or
sampler capable of sending samples as SDS data.
e Having the DPM V3 request a particular sample (as identified by a number) from a
sample-editing program or sampler capable of sending samples as SDS data.
Loop and sample length parameters in the source sample are retained in the DPM V3.
6.3a Sample Organization Within the DPM V3
A single sample that covers the entire keyrange will show up in the Oscillator 1 and 2
menus like any other wave, at the end of the factory waves. However, stretching a
single sample over the entire keyboard range is often sonically unsatisfactory — the
timbre resembles Darth Vader at the low end and the Munchkins at the high end due
to excessive transposition (like varying the speed control on a tape recorder by a large
amount). Therefore, the DPM V3 allows for multi-sampling, where several samples
(perhaps at octave or fifth intervals) are used to cover the keyboard range. Because
each sample only needs to be transposed over a narrow range, the timbre is more
realistic.
