# Namco 163 instrument editor
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)
- [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)
- [Wave len. to load] - sets length of waveform for load to RAM (4 nibble unit)
- [Waveform load] - sets the waveform load trigger behavior

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 continuously pre-loaded waveform and/or its sequences 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.
# effects
- `10xx`: set waveform for playback.
- `11xx`: set waveform position in RAM for playback. (single nibble unit)
- `12xx`: set waveform length in RAM for playback. (04 to FC, 4 nibble unit)
- `130x`: set playback waveform update behavior. (0: off, bit 0: update now, bit 1: update when every waveform is changed)
- `14xx`: set waveform for load to RAM.
- `15xx`: set waveform position for load to RAM. (single nibble unit)
- `16xx`: set waveform length for load to RAM. (04 to FC, 4 nibble unit)
- `170x`: set waveform load behavior. (0: off, bit 0: load now, bit 1: load when every waveform is changed)
- `180x`: set channel limit (0 to 7, x + 1)
- `20xx`: (Global) set waveform for load to RAM.
- `21xx`: (Global) set waveform position for load to RAM. (single nibble unit)
- `22xx`: (Global) set waveform length for load to RAM. (04 to FC, 4 nibble unit)
- `230x`: (Global) set waveform load behavior. (0: off, bit 0: load now, bit 1: load when every waveform is changed)

# Konami VRC6
Its one of NES mapper with sound expansion, and one of two VRCs with this feature by Konami.
the most popular expansion chip to the NES' sound system.
The chip has 2 pulse wave channel and single sawtooth channel.
volume register is 4 bit for pulse wave and 6 bit for sawtooth, but sawtooth output is corrupted when volume register value is too high. because this register is 8 bit accumulator in technically, its output is wraparoundable.
the chip has 2 pulse wave channels and one sawtooth channel.
volume register is 4 bit for pulse wave and 6 bit for sawtooth, but sawtooth output is corrupted when volume register value is too high. because this register is actually an 8 bit accumulator, its output may wrap around.
pulse wave duty cycle is 8 level, it can be ignored and it has potential for DAC at this case: volume register in this mode is DAC output and it can be PCM playback through this mode.
Furnace supports this routine for PCM playback, but it's consume a lot of CPU resource in real hardware. (even if conjunction with VRC6 integrated IRQ timer)

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.
Sound register layout
Address Bit Description
7654 3210
78-7f Channel 0
78 xxxx xxxx Channel 0 Pitch input bit 0-7
79 xxxx xxxx Channel 0 Accumulator bit 0-7*

7b xxxx xxxx Channel 0 Accumulator bit 8-15*
7c xxxx xx-- Channel 0 Waveform length, 256 - (x * 4)
---- --xx Channel 0 Pitch input bit 16-17
7d xxxx xxxx Channel 0 Accumulator bit 16-23*
7e xxxx xxxx Channel 0 Waveform base offset
xxxx xxx- RAM byte (0 to 127)
---- ---x RAM nibble
---- ---0 Low nibble
---- ---1 High nibble
7f ---- xxxx Channel 0 Volume
7f Number of active channels
7f -xxx ---- Number of active channels
-000 ---- Channel 0 activated
-001 ---- Channel 1 activated
-010 ---- Channel 2 activated
...
-110 ---- Channel 6 activated
-111 ---- Channel 7 activated
70-77 Channel 1 (Optional if activated)
68-6f Channel 2 (Optional if activated)
...
48-4f Channel 6 (Optional if activated)
40-47 Channel 7 (Optional if activated)
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)
