32 Here's a block diagram of how most of the cards work:
33
34 +-----------+
35 record | |<-------------------- Inputs
36 <-------| | |
37 PCI | Transport | |
38 bus | engine | \|/
39 ------->| | +-------+
40 play | |--->|monitor|-------> Outputs
41 +-----------+ | mixer |
42 +-------+
43
44 The lines going to and from the PCI bus represent "pipes". A pipe performs
45 audio transport - moving audio data to and from buffers on the host via
46 bus mastering.
47
48 The inputs and outputs on the right represent input and output "busses."
49 A bus is a physical, real connection to the outside world. An example
50 of a bus would be the 1/4" analog connectors on the back of Layla or
51 an RCA S/PDIF connector.
52
53 For most cards, there is a one-to-one correspondence between outputs
54 and busses; that is, each individual pipe is hard-wired to a single bus.
55
56 Cards that work this way are Darla20, Gina20, Layla20, Darla24, Gina24,
57 Layla24, Mona, and Indigo.
58
59
60 Mia has a feature called "virtual outputs."
61
62
63 +-----------+
64 record | |<----------------------------- Inputs
65 <-------| | |
66 PCI | Transport | |
67 bus | engine | \|/
68 ------->| | +------+ +-------+
69 play | |-->|vmixer|-->|monitor|-------> Outputs
70 +-----------+ +------+ | mixer |
71 +-------+
72
73
74 Obviously, the difference here is the box labeled "vmixer." Vmixer is
75 short for "virtual output mixer." For Mia, pipes are *not* hard-wired
76 to a single bus; the vmixer lets you mix any pipe to any bus in any
77 combination.
78
79 Note, however, that the left-hand side of the diagram is unchanged.
80 Transport works exactly the same way - the difference is in the mixer stage.
81
82
83 Pipes and busses are numbered starting at zero.
84
85
86
87 Pipe index
88 ==========
89
90 A number of calls in CEchoGals refer to a "pipe index". A pipe index is
91 a unique number for a pipe that unambiguously refers to a playback or record
92 pipe. Pipe indices are numbered starting with analog outputs, followed by
93 digital outputs, then analog inputs, then digital inputs.
94
95 Take Gina24 as an example:
96
97 Pipe index
98
99 0-7 Analog outputs (0 .. FirstDigitalBusOut-1)
100 8-15 Digital outputs (FirstDigitalBusOut .. NumBussesOut-1)
101 16-17 Analog inputs
102 18-25 Digital inputs
103
104
105 You get the pipe index by calling CEchoGals::OpenAudio; the other transport
106 functions take the pipe index as a parameter. If you need a pipe index for
107 some other reason, use the handy Makepipe_index method.
108
109
110 Some calls take a CChannelMask parameter; CChannelMask is a handy way to
111 group pipe indices.
112
113
114
115 Digital mode switch
116 ===================
117
118 Some cards (right now, Gina24, Layla24, and Mona) have a Digital Mode Switch
119 or DMS. Cards with a DMS can be set to one of three mutually exclusive
120 digital modes: S/PDIF RCA, S/PDIF optical, or ADAT optical.
121
122 This may create some confusion since ADAT optical is 8 channels wide and
123 S/PDIF is only two channels wide. Gina24, Layla24, and Mona handle this
124 by acting as if they always have 8 digital outs and ins. If you are in
125 either S/PDIF mode, the last 6 channels don't do anything - data sent
126 out these channels is thrown away and you will always record zeros.
127
128 Note that with Gina24, Layla24, and Mona, sample rates above 50 kHz are
129 only available if you have the card configured for S/PDIF optical or S/PDIF
130 RCA.
131
132
133
134 Double speed mode
135 =================
136
137 Some of the cards support 88.2 kHz and 96 kHz sampling (Darla24, Gina24,
138 Layla24, Mona, Mia, and Indigo). For these cards, the driver sometimes has
139 to worry about "double speed mode"; double speed mode applies whenever the
140 sampling rate is above 50 kHz.
141
142 For instance, Mona and Layla24 support word clock sync. However, they
143 actually support two different word clock modes - single speed (below
144 50 kHz) and double speed (above 50 kHz). The hardware detects if a single
145 or double speed word clock signal is present; the generic code uses that
146 information to determine which mode to use.
147
148 The generic code takes care of all this for you.

138Setting the sample rates on Layla24 is somewhat schizophrenic.
139
140For standard rates, it works exactly like Mona and Gina24. That is, for
1418, 11.025, 16, 22.05, 32, 44.1, 48, 88.2, and 96 kHz, you just set the
142appropriate bits in the control register and write the control register.
143
144In order to support MIDI time code sync (and possibly SMPTE LTC sync in
145the future), Layla24 also has "continuous sample rate mode". In this mode,
146Layla24 can generate any sample rate between 25 and 50 kHz inclusive, or
14750 to 100 kHz inclusive for double speed mode.
148
149To use continuous mode:
150
151-Set the clock select bits in the control register to 0xe (see the #define
152 below)
153
154-Set double-speed mode if you want to use sample rates above 50 kHz
155
156-Write the control register as you would normally
157
158-Now, you need to set the frequency register. First, you need to determine the
159 value for the frequency register. This is given by the following formula:
160
161frequency_reg = (LAYLA24_MAGIC_NUMBER / sample_rate) - 2
162
163Note the #define below for the magic number
164
165-Wait for the DSP handshake
166-Write the frequency_reg value to the .SampleRate field of the comm page
167-Send the vector command SET_LAYLA24_FREQUENCY_REG (see vmonkey.h)
168
169Once you have set the control register up for continuous mode, you can just
170write the frequency register to change the sample rate. This could be
171used for MIDI time code sync. For MTC sync, the control register is set for
172continuous mode. The driver then just keeps writing the
173SET_LAYLA24_FREQUENCY_REG command.
