// No official documentation was released for EMU10K1, but some info
// about playback can be extrapolated from the EMU8K documents:
// "AWE32/EMU8000 Programmer’s Guide" (emu8kpgm.pdf) - registers
// "AWE32 Developer's Information Pack" (adip301.pdf) - high-level view

// The short version:
// - The engine has 64 playback channels, also called voices. The channels
//   operate independently, except when paired for stereo (see below).
// - PCM samples are fetched into the cache; see description of CD0 below.
// - Samples are consumed at the rate CPF_CURRENTPITCH.
// - 8-bit samples are transformed upon use: cooked = (raw ^ 0x80) << 8
// - 8 samples are read at CCR_READADDRESS:CPF_FRACADDRESS and interpolated
//   according to CCCA_INTERPROM_*. With CCCA_INTERPROM_0 selected and a zero
//   CPF_FRACADDRESS, this results in CCR_READADDRESS[3] being used verbatim.
// - The value is multiplied by CVCF_CURRENTVOL.
// - The value goes through a filter with cutoff CVCF_CURRENTFILTER;
//   delay stages Z1 and Z2.
// - The value is added by so-called `sends` to 4 (EMU10K1) / 8 (EMU10K2)
//   of the 16 (EMU10K1) / 64 (EMU10K2) FX bus accumulators via FXRT*,
//   multiplied by a per-send amount (*_FXSENDAMOUNT_*).
//   The scaling of the send amounts is exponential-ish.
// - The DSP has a go at FXBUS* and outputs the values to EXTOUT* or EMU32OUT*.
// - The pitch, volume, and filter cutoff can be modulated by two envelope
//   engines and two low frequency oscillators.
// - To avoid abrupt changes to the parameters (which may cause audible
//   distortion), the modulation engine sets the target registers, towards
//   which the current registers "swerve" gradually.

/************************************************************************************************/
/* E-MU Digital Audio System overview								*/
/************************************************************************************************/

// - These cards use a regular PCI-attached Audigy chip (Alice2/Tina/Tina2);
//   the PCIe variants simply put the Audigy chip behind a PCI bridge.
// - All physical PCM I/O is routed through an additional FPGA; the regular
//   EXTIN/EXTOUT ports are unconnected.
// - The FPGA has a signal routing matrix, to connect each destination (output
//   socket or capture channel) to a source (input socket or playback channel).
// - The FPGA is controlled via Audigy's GPIO port, while sample data is
//   transmitted via proprietary EMU32 serial links. On first-generation
//   E-MU 1010 cards, Audigy's I2S inputs are also used for sample data.
// - The Audio/Micro Dock is attached to Hana via EDI, a "network" link.
// - The Audigy chip operates in slave mode; the clock is supplied by the FPGA.
//   Gen1 E-MU 1010 cards have two crystals (for 44.1 kHz and 48 kHz multiples),
//   while the later cards use a single crystal and a PLL chip.
// - The whole card is switched to 2x/4x mode to achieve 88.2/96/176.4/192 kHz
//   sample rates. Alice2/Tina keeps running at 44.1/48 kHz, but multiple channels
//   are bundled.
// - The number of available EMU32/EDI channels is hit in 2x/4x mode, so the total
//   number of usable inputs/outputs is limited, esp. with ADAT in use.
// - S/PDIF is unavailable in 4x mode (only over TOSLINK on newer 1010 cards) due
//   to being unspecified at 176.4/192 kHz. Therefore, the Dock's S/PDIF channels
//   can overlap with the Dock's ADC/DAC's high channels.
// - The code names are mentioned below and in the emu_chip_details table.
