Yamaha DTXpress/DTXplorer/DTXtreme

Hello all,

I have owned my DTXpress for about 5 years and play regularly.

The original kit came with the KP60 tricker tower, unfortunalety the 
trigger has been replaced on three occasions.

I have now purchased the new KP65 and note that it has an input 
socket and an output socket.

What do your use the input socket for, given that the mono lead 
would be connect to the output socket from the brain?

The unit did not come with any documentation to explain the use can 
someone please advise.

Regards

Mike
