[Jsynthlib-devel] Re: [jsynthlib-dev] Subclassing the Converte

[Jeff W. <jww...@ya...>]

Hiroo,

Thanks for your help. When I sat down to write my
driver, I went back and forth over whether to convert
the whole patch at once or to use a paramModel to do
it on the fly as you suggested. Apparently I made the
wrong choice. Shouldn't be too much work to change it
though.

But before I do I would like to get a better
understanding of the rest of your message. You said,
"By defining your patch class which implements IPatch
interface, you will be able to do what you wrote." I
took a look at the IPatch interface and I don't really
understand how that helps me. Can you explain a little
more about what you meant?

Thanks,
Jeff
