Using SysCtrl1, SysCtrl2, and Other Controllers in Realtime

1. There is a predefined list of controllers you can use to
realtime-control 
   - two predefined (of the up to 12) EFX-parameters and 
   - some definable patch-parameters. 
   DISADVANTAGES: They only work, when
   - set to the same channel as SYSTEM>CtlChannel (fact.preset = 16)
   - therefore they can only be used once in the Performance and
   - they may conflict with the main function of the controller (e.g.
when using CC 7 which 
      is part of the predefined list).

2. There is furthermore the possibility of choosing SysCtl1 and SysCtl2. 
   ADVANTAGES: 
   - They need not correspond with SYSTEM>CtlChannel and can therefore
be set (up to 16 times) to controll the parts of your performance(!) 
   - You can define any Controllers (eg GeneralPurpose1 = CC16,
GeneralPurpose2 = CC17) so they canīt get into conflict with other
controllers.
   DISADVANTAGE: You only have two of them.

3. Therefore I decided to use the following setup:
   - As one can use EFX only once in a performance, I have choosen those
two of the predefined controllers I donīt use at the moment (breath =
CC2 and foot = CC4) to control EFX and set SYSTEM>CTLCHANNEL to Channel
16 as well as the controllers send channel. 

   - So I saved the much more powerful SystemControllers for
"Patch-Work": I set SYSTEM>CtlAssign1 to CC16 and SYSTEM>CtlAssign2 to
CC17 and I set for all parts/patches PatchCtl2 to SysCtl1 and PatchCtl3
to SysCtl2  (remember that you canīt change PatchCtl1 from Mod. to
another ControlSource).

4. But all this doesīnt work if you forgot to set the effect-depth away
from Zero (this is the number after the controller you chose and it
works like this: eg depth = +20, that means: Sending a CC-value of 0
gives you the original tone, sending a CC-value of 64 adds a value of 10
to the effect etc. or you set depth to -10, that means: Sending a
CC-Value of 127 substracts the amount of 10 from the effect).
