This directory contains a few example envelope files, which can be used
to demonstrate some of the capabilities of envelopes. The files are listed
below, with a description of their effects when used as amplitude and pitch
envelopes.
Name Effect as Amplitude Envelope Effect as Pitch Envelope
---------- ---------------------------- ----------------------------
Amp-150 This is directly equivalent This will increase the pitch
to amplifying by 150% (1.5x) to 1.5 times its current level
Amp-50 This is directly equivalent This will decrease the pitch
to amplifying by 50% (0.5x) to 0.5 times its current level
LinRampDn Direct equivalent of the This will slow down the sample
simplest ramp down effect from normal pitch to very slow
LinRampUp Direct equivalent of the This will speed up the sample
simplest ramp up effect from very low pitch to normal
SawTooth This will superpose a -
sawtooth wave on the sample
when used with repeating on
Sine This will superpose a -
sine wave on the sample
when used with repeating on
SineBig The same as "Sine", but will
amplify the sample to 2x its
current level
Square This will superpose a -
square wave on the sample
when used with repeating on
The last envelope, LeftRight, when used as a stereo position envelope, will
cause a stereo sample to move from the leftmost position around to the
rightmost position. The center stereo position will occur at the point
where the envelope graph crosses the 'x1' line.
