YouÕll tweak the parameters on the AMPENV page when you want to shape the amplitude
characteristics of your sounds. A graphic view of the amplitude envelope will appear on the
display to give you a visual sense of the envelopeÕs characteristics. The dots along the envelope
graphic indicate the breakpoints between the envelopeÕs various segments. The small
horizontal arrow represents the end of the decay section. The small downward-pointing arrow
represents the beginning of the release section.
Because the K2vxÕs ROM samples are stored in a compressed format, applying an altered
amplitude envelope can change more than just the amplitude of your sound, since it also
changes the rate at which the samples are decompressed for playback. When the samples are
made to play back with altered envelopes, the timbres can evolve in new and interesting ways.
The AMPENV pageÕs top line gives you the usual location reminder, points out the currently
selected layer, and tells you the relative scale of the envelopeÕs graphic view. The envelope
graphic shrinks in scale as the segment times get longer. This auto-zoom feature maximizes the
available display space. Try lengthening one of the segment times. The envelope graphic will
stretch to Þll the display from left to right. When it Þlls the display, it will shrink to half its size,
and the top line will indicate that the scale has changed (from [1/1] to [1/2], for example).
Each parameter on this page has two values, as listed below. For the envelope segments, the
Þrst (upper) value is the duration of the segment, and the second is the amplitude level at the
completion of the segment. For the Loop parameter, the values deÞne how the envelope loops,
and how many times the loop cycles.
PARAMETER RANGE OF VALUES
ATTACK SEGMENT 1, 2, 3 TIME 0 to 60 seconds
LEVEL 0 to 100 %
DECAY SEGMENT TIME 0 to 60 seconds
LEVEL 0 to 100 %
RELEASE SEGMENT 1, 2, 3 TIME 0 to 60 seconds
LEVEL 0 to 100 %
LOOP TYPE Off, Forward, Bidirectional
# OF LOOPS Infinite, 1 to 31 times
Attack Segment Times
These indicate how long it takes for the current layerÕs amplitude to reach its Þnal level from its
starting level.
Attack Segment Levels
These are the Þnal levels that each segment achieves at completion. The levels are expressed as
percentages of the maximum possible amplitude for the current layer. Attack segment 1 always
