# Namco 163 instrument editor
|
||||
|
||||
Namco 163 instrument editor consists of 10 macros.
|
||||
Namco 163 instrument editor consists of two tabs: one controlling various parameters for waveform initialize and macro tab containing 10 macros.
|
||||
|
||||
## N163
|
||||
- [Initial Waveform] - Determines the initial waveform for playing.
|
||||
- [Initial Waveform position in RAM] - Determines the initial waveform position will be load to RAM.
|
||||
- [Initial Waveform length in RAM] - Determines the initial waveform length will be load to RAM.
|
||||
- [Load waveform before playback] - Determines the load initial waveform into RAM before playback.
|
||||
- [Update waveforms into RAM when every waveform changes] - Determines the update every different waveform changes in playback.
|
||||
|
||||
|
||||
## Macros
|
||||
- [Volume] - volume levels sequence
|
||||
- [Arpeggio]- pitch sequence
|
||||
- [Waveform pos.] - sets the waveform source address in RAM for playback (single nibble unit)
