Roland MV8800 Manual

Sampler structure

The sampler consists of “samples,” which are stored in wave memory, and two types of sound generators ---

“Instrument” and “Audio Phrase” — which allow these samples to be played using the velocity pads and the sequencer.

The Instrument sound generator is the appropriate choice when you want to play the sounds of pitched instruments such as a piano, or instruments such as a drum set, for which each velocity pad (note) will have a different sound.

The Audio Phrase sound generator is the appropriate one for handling looped phrases or vocal phrases of several measures, since the phrase can be synchronized to the sequencer’s tempo without changing the pitch of the phrase.

Samples

Each piece of waveform data in wave memory is called a “sample.”

Samples are created by the following operations.

• Sampling

• Importing (loading) a file from hard disk or CD-ROM

• Recording to an audio track

Samples cannot be played directly from the velocity pads or sequencer. In order to play samples, you must assign the samples to a patch used by an instrument, or assign a sample to an audio phrase.

Patches

A “patch” is a set of sounds played from the velocity pads or the sequencer. A patch is analogous to an instrument such as a piano or drum set. Each patch is created by assigning sounds called “partials” to each velocity pad (each note). Up to 96 partials can be assigned to one patch.

Partials

Partials are the ingredients from which a patch is constructed. In the case of a drum set patch, each separate sound such as snare or hi-hat corresponds to a different partial.

Adds cyclic change.

Partial

Each partial consists of the following six things.

● SMT (Sample Mix Table)

This assigns the samples that are the basis for the partial’s sound. You can assign up to four samples to the

SMT. If desired, you can make settings so that different samples will sound depending on how strongly you play a velocity pad.

● Filter

This specifies how the frequency content of the sound will change.

● Amplifier

This specifies the volume and panning (stereo position).

● Filter Envelope

This specifies how the frequency content will change over time.

● Amp Envelope

This specifies how the volume will change over time.

● LFO (Low Frequency Oscillator)

This specifies cyclic change (modulation). You can use the LFO to modulate the pitch, filter, or amp. Applying

LFO to the pitch produces vibrato, applying it to the filter produces wah, and applying it to the amp produces tremolo.

Instruments

Instruments are where you can assign patches so that the patches can be played from the velocity pads or sequencer. Each instrument has sixteen “parts,” and can handle sixteen patches simultaneously.

Audio phrases

Since audio phrases can be synchronized to the tempo of the sequencer without changing their pitch, they are appropriate for handling loop phrases or vocal phrases of several measures in length.
