# Namco 163 instrument editor

Namco 163 instrument editor consists of 10 macros.

- [Arpeggio]- pitch sequence

- [Waveform] - sets waveform source for playback immediately or update later

- [Waveform len.] - sets the waveform source length for playback (4 nibble unit)
|

- [Waveform update] - sets the waveform update trigger behavior for playback

- [Waveform to load] - sets waveform source for load to RAM immediately or later
|

- [Wave pos. to load] - sets address of waveform for load to RAM (single nibble unit)
|

Wavetable synthizers, in context of Furnace, are sound sources that operate on extremely short n-bit PCM streams. By extremely short, no more than 256 bytes. This amount of space is nowhere near enough to store an actual sampled sound, it allows certain amount of freedom to define a waveform shape. As of Furnace 0.5.8, wavetable editor affects PC Engine, WonderSwan and channel 3 of Game Boy.
|
||||
|
||||
Furnace's wavetable editor is rather simple, you can draw the waveform using mouse or by pasting an MML bit stream in the input field. Maximum wave width (length) is 256 bytes, and maximum wave height (depth) is 256. NOTE: Game Boy, PCE, WonderSwan and Bubble System can handle max 32 byte waveforms, X1-010 can handle max 128 byte waveforms as of now, with 16-level height for GB, X1-010 Envelope, WS and Bubble System, and 32-level height for PCE. If larger wave will be defined for these systems, it will be squashed to fit within the constraints of the system.

# Namco 163
|
||||
|
||||
This is Namco's one of NES mapper, with up to 8 wavetable channels. It has also 128 byte of internal RAM, both channel register and wavetables are stored here. Wavetables are variable size and freely allocable anywhere in RAM, it means it can be uses part of or merged 2 or more pre-loaded waveforms in RAM. But waveform RAM area becomes smaller as much as activating more channels; Channel register consumes 8 byte for each channels. You must avoid conflict with channel register area and waveform for avoid channel playback broken.
|
||||
|
||||
It has can be outputs only single channel at clock; so it's sound quality is more crunchy as much as activating more channels.
|
||||
|
||||
Furnace supports both load waveform into RAM and waveform playback simultaneously, and channel limit is dynamically changeable with effect commands.
|
||||
You must load waveform to RAM first for playback or do something, its load behavior is changeable to auto-update when every waveform changes or manual update.
|
||||
Both waveform playback and load command is works independently per each channel columns, (Global) commands are don't care about the channel columns for work commands and its load behavior is independent with per-channel column load commands.
|
||||

||||

Namco 163 Sound emulation core
|
||||
|
||||
This chip is one of NES mapper with sound expansion, This one is by Namco.
|
||||
|
||||
It has 1 to 8 wavetable channels, All channel registers and waveforms are stored to internal RAM.
|
||||
4 bit Waveforms are freely allocatable, and its length is variables; its can be stores many short waveforms or few long waveforms in RAM.
|
||||
|
||||
But waveforms are needs to squash, reallocate to avoid conflict with channel register area, each channel register size is 8 bytes per channels.
|
||||
|
||||
Sound output is time division multiplexed, it's can be captured only single channels output at once. in reason, More activated channels are less sound quality.
|
||||
|
||||

|

Rest of RAM area are for 4 bit Waveform and/or scratchpad.
|

Each waveform byte has 2 nibbles packed, fetches LSB first, MSB next.
|

---- xxxx 4 bit waveform, LSB
|

xxxx ---- Same as above, MSB
|

|

Waveform address: Waveform base offset + Bit 16 to 23 of Accumulator, 1 LSB of result is nibble select, 7 MSB of result is Byte address in RAM.
|

||||
Frequency formula:
|

Frequency: Pitch input * ((Input clock * 15 * Number of activated voices) / 65536)
