| # NES instrument editor
 | |
| 
 | |
| the NES instrument editor consists of two tabs.
 | |
| 
 | |
| ## DPCM
 | |
| 
 | |
| this tab is somewhat similar to [the Sample instrument editor](sample.md), but it has been tailored for use with NES' DPCM channel.
 | |
| 
 | |
| - **Sample**: specifies which sample should be assigned to the instrument.
 | |
| - **Use sample map**: enables mapping different samples to notes. see next section for more information.
 | |
|   - when this option is disabled, 16 notes (from C-0 to D#1 and repeating) will map to the DPCM channel's 16 possible pitches.
 | |
| 
 | |
| ### sample map
 | |
| 
 | |
| the sample map allows you to set a sample for each note.
 | |
| 
 | |
| 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 DPCM pitch at which the specified sample will play.
 | |
|   - for possible values, refer to the table below.
 | |
|   - you may press Delete to clear it. if no value is specified, the last pitch is used.
 | |
| - the fourth column allows you to set the initial delta counter value when playing the sample.
 | |
|   - this is an hexadecimal number.
 | |
|   - the range is `00` to `7F`.
 | |
|   - you may press Delete to clear it. if no value is specified, the delta counter isn't altered.
 | |
| - the fifth and last column provides a combo box for selecting a sample.
 | |
| 
 | |
| you may right-click anywhere in the number, pitch and delta columns for additional options:
 | |
| - **set entire map to this pitch**: sets the DPCM pitch of all notes to the selected cell's.
 | |
| - **set entire map to this delta counter value**: sets the initial delta counter value 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 pitches**: resets the sample map's DPCM pitches to defaults (15).
 | |
| - **clear delta counter values**: removes all delta counter values from the map.
 | |
| - **clear map samples**: removes all samples from the map.
 | |
| 
 | |
| ## Macros
 | |
| 
 | |
| - **Volume**: volume sequence.
 | |
| - **Arpeggio**: pitch sequence.
 | |
| - **Duty/Noise**: duty cycle and noise mode.
 | |
|   - pulse duty cycles:
 | |
|     - `0`: 12.5%
 | |
|     - `1`: 25%
 | |
|     - `2`: 50%
 | |
|     - `3`: 75%
 | |
|   - noise modes:
 | |
|     - `0`: long noise
 | |
|     - `1`: short noise
 | |
| - **Pitch**: fine pitch.
 | |
| - **Phase Reset**: trigger restart of waveform.
