I do what it said here
http://www.megadrum.info/content/settin ... One cymbal
except the part about the bell ... as you tell me in my case (dual piezzo)
To make a test I plugged my cymbal on the crash input of the MD.
Back in MDM the Head entry default is to single piezo and in that case I get a sound of crash cymbal emitted from AD, as soon as I put the piezo head on "3 way roland" and the rim piezo on "switch "to activate the choke function I do not have the cymbal sound but a tom sound it is very strange and no choke function and if I put the rim piezo on "single piezo" I have the sound of the crash that is mixing sometime with the sound of a tom but I got to the choke function randomly work ... I don't understand
*Note that I do the test with only the cymbal connected to the MD all other elements of the drum are not connected to the MD.
