I add support for 3 zone Yamaha style cymbals in firmware version 20081020.
This is a rough guide to configuring 3 zone Yamaha style cymbals with MegaDrum.
This is a schematic of a 3 zone Yamaha style cymbal (thanks to elrules for digging it up):
Say you connect it to a Ride input.
1. Set RideB->Note to a Ride Bow note.
2. Set RideB->Dual Head to 'Yes' (NOT 3way!).
3. Set RideE->Note to a Ride Edge note.
4. Set RideE->Threshold between 55 and 70. My test setup works best around 60
5. Set RideE->Type to 'Switch'
6. Set RideE->BNote to a Ride Bell note.
7. Set RideE->BThreshold between 18 and 40. My test setup works best around 25
These are minimum required steps for configuring a 3 zone Yamaha style cymbal. Of course you will need to adjust all other settings for the Ride to get best results.
