As long as both have bell, bow, edge and choke (what I need when I build mine)... I'm tempted to be indifferent, but having that compatibility would be great just for the sake of open endedness...
Roland cymbals (like CY-15) use two jacks. One is labelled as "bow/edge" and the other as "bow/bell". It is like having two dual zone cymbals joined together. You need to use two stereo inputs of megadrum (and activate 3way option in the config of one input) to be able to use the 3 zones in normal way.
Yamaha cymbals use only one input. Both switches (edge and bell) are connected to "ring" of jack. You only need to use one stereo input of the module. You will wonder: how does the module distinguish them? It does it because one switch is conected directly to the ring of jack and the other has a 10kOhm resistor in series. The yamaha module can measure that difference in resistance seen between ring and ground to trigger one sound or another.
There is another difference besides the design one, that is, in price.
Roland CY-15 (a trizone 15'' ride) costs 222€

http://www.thomann.de/es/yamaha_pcy150s ... al_pad.htmPersonally, I own a yamaha pcy150s. Before megadrum, I used it with a roland module and I couldn't use the 3 zones but I was very happy with it as it has a very good sensitivity and it is very quiet when playing.
For someone who wants to buy trizone cymbals, (at least for me) seems better to buy cymbals 100€ cheaper and that only spend one input in my module to do the same as the others. That was the reason I have insisted so much dmitri of implementing it.
But it is not limited to "buying" cymbals. THe yamaha design has been discovered for DIYers and it is easy to copy that design in a DIY way. I have built a roland-style cy-15. If dmitri implements that feature it would be easy to rebuild it: remove one jack, add a 10k resistor to one switch and connect it to the same remaining jack.
Hope I can help
