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.

# Commodore VIC-20
|
||||
|
||||
The Commodore VIC-20 was Commodore's major attempt at making a personal home computer, and is the percursor to the Commodore 64. The VIC-20 was also known as the VC-20 in Germany, and the VIC-1001 in Japan.
|
||||
|
||||
It has 4 PSG voices that has a limited but wide tuning range, and like the SN76489, the last voice is dedicated to playing pseudo-white noise.
|
||||
|
||||
The 3 pulse wave channels also have different octaves that they can play notes on. The first channel is the bass channel, and it can play notes from octave 1. The next is the 'mid/chord' channel, and it plays notes from octave 2. And rather obviously, the 3rd pulse channel is typically the lead channel, can play notes from octave 3.

# Konami VRC6

the most popular expansion chip to the NES' sound system.
|
||||
|
||||
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 consumes a lot of CPU time in real hardware (even if conjunction with VRC6's 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.

||||

||||

Konami VRC VI sound emulation core
|
||||
|
||||
It's one of NES mapper with built-in sound chip, and also one of 2 Konami VRCs with this feature. (rest one has OPLL derivatives.)
|
||||
|
||||
It's also DACless like other sound chip and mapper-with-sound manufactured by konami,
|
||||
the Chips 6 bit digital sound output is needs converted to analog sound output when you it want to make some sounds, or send to sound mixer.
|
||||
|
||||
Its are used for Akumajou Densetsu (Japan release of Castlevania III), Madara, Esper Dream 2.
|
||||
|
||||
The chip is installed in 351951 PCB and 351949A PCB.
|
||||
|
||||
351951 PCB is used exclusivly for Akumajou Densetsu, Small board has VRC VI, PRG and CHR ROM.
|
||||
- It's configuration also calls VRC6a, iNES mapper 024.
|
||||
|
||||
351949A PCB is for Last 2 titles with VRC VI, Bigger board has VRC VI, PRG and CHR ROM, and Battery Backed 8K x 8 bit SRAM.
|
||||
- Additionally, It's PRG A0 and A1 bit to VRC VI input is swapped, compare to above.
|
||||
- It's configuration also calls VRC6b, iNES mapper 026.
|
||||
|
||||
The chip itself has 053328, 053329, 053330 Revision, but Its difference between revision is unknown.
|
||||
|
||||
Like other mappers for NES, It has internal timer - Its timer can be sync with scanline like other Konami mapper in this era.

||||
