18.1 Patch Editor
The Patch Editor allows you to modify existing patches or create new patches.

A patch consists of one or more samples. A sample is an audio file containing a single note of the
instrument the patch is for (for instance a single piano key hit).
Samples
Samples can be triggered by three trigger sources: "Note On", "Note On with Sustain" and "Note Off". Most
patches use "Note On" samples only. "Note On with Sustain" samples are used instead if the Sustain pedal
is down at when the note is played. "Note Off" samples are fired when a note ends. The Match Note-Off
Levels button can be used to automatically match the level of the "Note Off" sample with the current level
of the playing note. The sample's Gain property determines the highest allowed level in this situation.
of the playing note. The sample's Gain property determines the highest allowed level in this situation.
"Note On with Sustain" and "Note Off" samples will typically be used for large piano patches.
For every sample the following properties must be defined:
l
Note: The note of the recorded sample (for instance 'C5')
l
Layer: The velocity layer the sample is in. Velocity is zero on the left, and 127 on the right. The active
region appears in color. A region can be activated by clicking the mouse on it. See also Layer
Thresholds.
l
Sample File: Audio file containing the sample. Can be either mono or stereo.
l
Samplerate: The samplerate of the audio file (for instance '44100'). This parameter can also be used
for fine-tuning (for instance: multiplying the samplerate with 1.0116 increases the perceived pitch by
20 cents).
The following properties are optional:
l
Lowest Note: The lowest note this sample will be used for. Use this to override the Sampler's default
note-assignment rules, or to set the lowest note the patch can produce.
note-assignment rules, or to set the lowest note the patch can produce.
l
Highest Note: The highest note this sample will be used for. Use this to override the Sampler's
default note-assignment rules, or to set the highest note the patch can produce.
l
LoopStart: The position in samples at which the loop starts.
l
LoopEnd: The position in samples at which the loop ends. Should always be higher than LoopStart.
l
LoopGain: The relative volume level of each consecutive passage through the loop (for instance
'0.900'). If loopgain is equal to the sample's level at LoopEnd divided by the level at LoopStart a
natural decay results.

l
Gain: Gain level, 1.000 is neutral
