+ *  This card has two mixers and two PCM devices.  I've cheesed it such
+ *  that recording and playback can be done through the same device.
+ *  The driver "magically" routes the capturing to the AD1848 codec,
+ *  and playback to the SB16 codec.  This allows for full-duplex mode
+ *  to some extent.
+ *  The utilities in alsa-utils are aware of both devices, so passing
+ *  the appropriate parameters to amixer and alsactl will give you
+ *  full control over both mixers.

+ * Linux multisound pinnacle/fiji driver for ALSA.
+ *
+ * 2002/06/30 Karsten Wiese:
+ *	for now this is only used to build a pinnacle / fiji driver.
+ *	the OSS parent of this code is designed to also support
+ *	the multisound classic via the file msnd_classic.c.
+ *	to make it easier for some brave heart to implemt classic
+ *	support in alsa, i left all the MSND_CLASSIC tokens in this file.
+ *	but for now this untested & undone.
+ *
+ * ripped from linux kernel 2.4.18 by Karsten Wiese.
+ *
+ * the following is a copy of the 2.4.18 OSS FREE file-heading comment:
+ *
+ * Turtle Beach MultiSound Sound Card Driver for Linux
+ * msnd_pinnacle.c / msnd_classic.c
+ *
+ * -- If MSND_CLASSIC is defined:
+ *
+ *     -> driver for Turtle Beach Classic/Monterey/Tahiti
+ *
+ * -- Else
+ *
+ *     -> driver for Turtle Beach Pinnacle/Fiji
+ *

+/* The low level driver for the WaveFront ICS2115 MIDI interface(s)
+ *
+ * Note that there is also an MPU-401 emulation (actually, a UART-401
+ * emulation) on the CS4232 on the Tropez and Tropez Plus. This code
+ * has nothing to do with that interface at all.
+ *
+ * The interface is essentially just a UART-401, but is has the
+ * interesting property of supporting what Turtle Beach called
+ * "Virtual MIDI" mode. In this mode, there are effectively *two*
+ * MIDI buses accessible via the interface, one that is routed
+ * solely to/from the external WaveFront synthesizer and the other
+ * corresponding to the pin/socket connector used to link external
+ * MIDI devices to the board.
+ *
+ * This driver fully supports this mode, allowing two distinct MIDI
+ * busses to be used completely independently, giving 32 channels of
+ * MIDI routing, 16 to the WaveFront synth and 16 to the external MIDI
+ * bus. The devices are named /dev/snd/midiCnD0 and /dev/snd/midiCnD1,
+ * where `n' is the card number. Note that the device numbers may be
+ * something other than 0 and 1 if the CS4232 UART/MPU-401 interface
+ * is enabled.
+ *
+ * Switching between the two is accomplished externally by the driver
+ * using the two otherwise unused MIDI bytes. See the code for more details.
+ *
+ * NOTE: VIRTUAL MIDI MODE IS ON BY DEFAULT (see lowlevel/isa/wavefront.c)
+ *
+ * The main reason to turn off Virtual MIDI mode is when you want to
+ * tightly couple the WaveFront synth with an external MIDI
+ * device. You won't be able to distinguish the source of any MIDI
+ * data except via SysEx ID, but thats probably OK, since for the most
+ * part, the WaveFront won't be sending any MIDI data at all.
+ *  
+ * The main reason to turn on Virtual MIDI Mode is to provide two
+ * completely independent 16-channel MIDI buses, one to the
+ * WaveFront and one to any external MIDI devices. Given the 32
+ * voice nature of the WaveFront, its pretty easy to find a use
+ * for all 16 channels driving just that synth.

+potentially > 0x7F (127) must be split across multiple bytes.
+
+Sometimes, we need to munge numeric values that are represented on
+the x86 side as 8-32 bit values. Sometimes, we need to munge data
+that is represented on the x86 side as an array of bytes. The most
+efficient approach to handling both cases seems to be to use 2
+different functions for munging and 2 for de-munging. This avoids
+weird casting and worrying about bit-level offsets.
