What is VariPhrase?
VariPhrase is proprietary Roland technology that uses newly developed encoding methods with
several algorithms to analyze and extract the three elements of sound—pitch, time, and formant (tonal
character)—from the sample, allowing you to control these independently in real time.

This opens up possibilities for completely new performance expressions and sound design that were
unavailable on previous synthesizers or samplers.
On a conventional sampler, using phrase samples involved the following problems:
• Changing the tempo affected the pitch.
• Changing the pitch of a vocal sample would also change the playback speed (time) and tonal
character (formant).
• The sampled phrase was simply played back, and could not be varied.
• Since one sample could cover a range of only a few keys, you needed samples at multiple pitches
if you wanted to play a wider range.
• If you wanted to play multiple samples in synchronization, the samples had to be at the identical
tempo.
• If you play the keys in a chord at different moments, the sounds are heard out of sync with each
other.
• Changing the pitch or tempo degrades the sound quality.
VariPhrase eliminates all of the above problems.

On a conventional sampler,
pitch, time, and formant
always change together.
When you use VariPhrase Solo
encoding, time and formant will
remain fixed, and only the pitch
will vary. This lets a single
sample cover a wider range of
notes.
Original phrase
Record the words
"Here comes VariPhrase"
sung at a constant pitch.
VariPhrase lets you control the
phrase in real time. As shown
here, you can freely and
independently control the pitch,
time, and formant even while the
phrase is playing.
