/* |
165 |
|
The sampler state is stored in a text base format, designed to |
166 |
|
be easy to parse with the istream >> operator. Values are |
167 |
|
separated by spaces or newlines. All string values that may |
168 |
|
contain spaces end with a newline. |
169 |
|
|
170 |
|
The first line contains the global volume. |
171 |
|
|
172 |
|
The rest of the lines have an integer first representing the |
173 |
|
type of information on the line, except for the two lines that |
174 |
|
describe each sampler channel. The first of these two starts |
175 |
|
with an integer from 0 to 16 (the midi channel for the sampler |
176 |
|
channel). |
177 |
|
|
178 |
|
Note that we should try to keep the parsing of this format both |
179 |
|
backwards and forwards compatible between versions. The parser |
180 |
|
ignores lines with unknown type integers and accepts that new |
181 |
|
types are missing. |
