Amiga/PCM sound source instrument editor

the Generic Sample instrument editor consists of a sample selector and several macros:

Sample

• Sample: specifies which sample should be assigned to the instrument.
• Use wavetable: uses wavetable instead of a sample.
  • only available in Amiga and Generic PCM DAC.
• Use sample map: enables mapping different samples to notes. see next section for more information.

sample map

the sample map allows you to set a sample for each note. this can be used to create more realistic instruments, split key instruments, drum kits and more.

after enabling this option, a table appears with the contents of the sample map.

• the first column represents the input note.
• the second column allows you to type in a sample number for each note.
  • you may press Delete to clear it.
• the third one is used to set the note at which the specified sample will play.
• the fourth and last column provides a combo box for selecting a sample.

you may right-click anywhere in the number and note columns for additional options:

• set entire map to this note: sets the note number of all notes to the selected cell's.
• set entire map to this sample: sets the sample number of all notes to the selected cell's.
• reset notes: resets the sample map's notes to defaults (a chromatic scale).
• clear map samples: removes all samples from the map.

Macros

• Volume: volume sequence. does not apply to some chips.
• Arpeggio: pitch sequence.
• Waveform: waveform sequence.
  • only appears when "Use wavetable" is enabled.
• Panning (left): output level for left channel.
• Panning (right): output level for right channel.
• Pitch: fine pitch.
• Phase Reset: trigger restart of waveform.
