This is a question to all VST-coders
To build a sampler is easy, but how do you store the filename? Normaly I only have things, that can be stored as a number and I can use a VST-Parameter for that. So e.g. cubase will store the value with the song. But what about a path to a sample? how to store that?

You should use chunks to save your data with the host (check out getCunk, setChunk). Whats inside the chunk is totally up to you (its just a stream of bytes), filename, sample data or whatever you want.

Since samplers usually don't have a fixed set of samples/programs, you never know how many VST params to have in yuor plug. So what you can do is expose a fixed set of params, lets say 32, and then let the user map VST params to sample params. Example: param 1 -> prog 1 sample 4 filter cutoff.

Doh! just told you the secret of Cyber 1.01.
