Roland DJ-70 Supplemental Notes

May 23, 1997
This document will cover variety of topics related to the operation of the DJ-70 and DJ-70MKII. We will begin with an
overview of the Roland Sampler architecture and move on to basic operations such as loading Patches and creating
Performances. Next, we will discuss the SCSI interface and related topics such as formatting and loading data from
an external SCSI drive. In the sequencer section, we will cover operation of the built-in RPS sequencer as well as
the setup involved when using the DJ-70/DJ-70MKII with an external MIDI sequencer. We will also provide step by
step instruction on recording and editing your own Samples. We will show you how to synchronize the tempos of
multiple Samples (DJ-70MKII) and how you can access other sound libraries by using the Convert Load function. If
you need additional sampling time, we will cover the necessary steps for memory installation. Finally, we will discuss
Sample transfers through SCSI with some specific software programs (DJ-70MKII).
I. Overview
Before we get into instructions on how to use the DJ-70/DJ-70MKII, it is a good idea to understand the Roland
Sampler architecture.
Sample
A Sample is the basic element of sound in the DJ-70 or DJ-70MKII's architecture. A Sample is a raw recording of
a sound (mono or stereo) of any length (depending on the amount of available memory). When you create or load
a Sample on the DJ-70/DJ-70MKII it is stored in RAM in one of the 512 available locations. Samples can also be
stored on floppy disks provided they don't require more memory than is available on the floppy disk itself.
Partial
A Partial is a combination of up to four Samples. These Samples can be played simultaneously or velocity-switched
and crossfaded. Each Sample within the Partial can have its own level, tuning (relative to the original recorded
pitch), output assignment, and pan position. In addition to combining Samples, the DJ-70/DJ-70MKII's synthesis
functions are applied on the Partial level. All Samples within a Partial share the same filter, envelope, and LFO
settings.
Patch
Patches are essentially combinations of Partials that are assigned to the keyboard. While it is possible to assign a
different Partial for every key on the keyboard, you can not assign multiple Partials to a single key. In a Patch,
MIDI data such as pitch bend, channel pressure, and continuous controller messages can be assigned to
parameters such as pitch, volume, filter (TVF) depth, and vibrato (LFO). Each Patch also has its own level and
tuning settings that can be used to augment or override the Partial settings. A maximum of 128 Patches can be
stored in RAM at any one time. The actual number will depend on the amount of available memory and the size of
the Samples used in each Patch.
