Move comments to better locations, de-duplicate, fix/remove incorrect/
outdated ones, add new ones, and unify spacing somewhat.
While at it, also add testing credits for Jonathan Dowland (SB Live!
Platinum) and myself (E-MU 0404b).

+// "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.

+// - 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.
