// - 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.

// 32 cache registers (== 128 bytes) per channel follow.
// In stereo mode, the two channels' caches are concatenated into one,

// The cache holds 64 frames, so the upper half is not used in 8-bit mode.

// CA = CCCA_CURRADDR, CRA = CCR_READADDRESS,
// CLA = CCR_CACHELOOPADDRHI:CLP_CACHELOOPADDR,
// CIS = CCR_CACHEINVALIDSIZE, LIS = CCR_LOOPINVALSIZE,
// CLF = CCR_CACHELOOPFLAG, LF = CCR_LOOPFLAG
// The cache is a ring buffer; CRA operates modulo 64.
// The cache is filled from (CA - CIS) into (CRA - CIS).
// The engine has a fetch threshold of 32 bytes, so it tries to keep
// CIS below 8 (16-bit stereo), 16 (16-bit mono, 8-bit stereo), or
// 32 (8-bit mono). The actual transfers are pretty unpredictable,
// especially if several voices are running.
// Frames are consumed at CRA, which is incremented afterwards,
// along with CA and CIS. This implies that the actual playback
// position always lags CA by exactly 64 frames.
// When CA reaches DSL_LOOPENDADDR, LF is set for one frame's time.
// LF's rising edge causes the current values of CA and CIS to be
// copied into CLA and LIS, resp., and CLF to be set.
// If CLF is set, the first LIS of the CIS frames are instead
// filled from (CLA - LIS), and CLF is subsequently reset.

/* 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.
