# Super NES
|
||||
|
||||
The successor to NES to compete with Genesis. Now packing with superior graphics and sample-based audio. Also known as Super Famicom.
|
||||
|
||||
Its audio subsystem, developed by Sony, features the DSP chip, SPC700 microcontroller and 64KB of dedicated SRAM used by both. This whole system itself is pretty much a separate computer that the main CPU needs to upload its program and samples to.
|
||||
|
||||
The DSP chip can
|
||||
|
||||
Furnace communicates with the DSP directly and provide a full 64KB memory. This memory might be reduced excessively on ROM export to make up for playback engine and pattern data.
|
||||
|
||||
# effects
|
||||
|
||||
Note: this chip has a signed left/right level. Which can be used for inverted (surround) stereo. A signed 8-bit value means 80 - FF = -128 - -1. Other values work normally. A value of -128 is not recommended as it could cause overflows.
|
||||
|
||||
- `10xx`: Set echo feedback level. This effect will apply to all channels.
|
||||
- `11xx`: Set echo left level (signed 8-bit). This effect will apply to all channels.
|
||||
- `12xx`: Set echo right level (signed 8-bit). This effect will apply to all channels.
|
||||
- `13xx`: Set the length of the echo delay buffer. This will also affect the size of the sample RAM!
