Add simpler.
Add an open hihat sample.
Set simplers envelope to short decay/release time:
Set it so it plays exactly as long as your midi notes plays.
Create some midi clips with notes playing 16ths or what have you.
Mute the channel.
Group the track.
on the group track load the Gate plug.
Open its side chain for the hihat.
Create a rack of the Gate.
Assign its parameters to the Rack Macros.
Create a rack of the rack.
Create a second parallel chain in the master rack:
Duplicate the chain inside so you get 2 in parallel.
Delete the Rack inside chain 2.
Set one master rack macro to fade between chain1 and chain2:
Open the master rack and X-fade the chains.
Assign the chain selector: this will be the dry/wet.
Assign macros on the master rack to whats on chain 1s gate rack.
Rename and save this group track by dragging it to your racks and tracks library, or whatever file system you are using. Right click it when its in the project and make shore its collected and saved with the hihat sample.
Now, anytime you need to "trance" gate something, drag this group track into the Live set.
When its in, copy paste the Gate rack to wherever you want a gate. From here on, copy paste the rack from within the Live set to as many places as you need it. This will keep the patching for the side chaining. If you drag just the rack into the Live set from the Live browser, the side chain patching will be lost. Thats why its best to keep a clean version in the master gate track.
all your gate is belong to us.
