"""Returns a tuple: dict, sw_lokey, sw_highkey |
|||
|

dict with key=keystring e.g. c#4 |
|||
and value=(opcode,label). label can be empty. |
|||
|
|||
Only existing keyswitches are included, not every number from 0-127. |
|||
Two special keys "sw_lokey" and "sw_hikeys" are returned and show the total range of possible |
|||
keyswitches. |
|||
|
|||
This is just a function to find the keyswitches in our example, not every advanced scenario |
|||
with sw_previous for context-sensitive-regions (which isn't really a keyswitch), |
|||
nor sw_lokey, sw_hikey and multiple parallel switches per key. |
|||
|
|||
Specifically it just searches for sw_last, sw_down and sw_up and assumes that any level (master, |
|||
group, region) can only use one of the three. |
|||
|
|||
sw_down and sw_up are implementation-dependent. We must assume that there are instruments that |
|||
use these opcodes without specifying sw_lokey and sw_hikey. sw_last requires the range. |
|||
For these reasons we cannot do sanity-checking here. We just report all single-key keyswitches. |
|||
|
|||
Finally it assumes that there is one sw_lokey and one sw_hikey in the whole file, and it |
|||
must be in global. No actual keyswitches will be in global. |
