Newbie help please - using Maize with Cubase SE

[Fluteytooter]

Hi - Could someone please talk me in detail how to play my sampled instrument as a vst in Cubase SE?

Here's what I did:

Allocated my wavs to each piano key by dragging and dropping. They play OK both on the screen keyboard and on my music midi keyboard.

Set instrument name to "Flute_29" (the name of my sampled flute I am creating).

Left other fields as - Midi ch 1, Audio ch 1 PB 1.

In Options, changed name to "Flute_29 maize".

Hit Export.

I got: A folder containing Fl_29 maize.msb, a Fl_29 maize.dll file and a Fl_29 maize.mss file.

I put the dll in my vstpugins folder and ran Cubase SE.

Fl_29 maize comes up in the instrument list. I connected my flute track to this instrument and set it to midi channel 1. No sound.

Hit edit for the track and the maize sampler appears, but showing "instrument: null"

Here's my problem - how do I now get it to play my flute sound. If anyone could talk me through this, I'd be etrernally grateful!
Cheers
Jon

make sure you copy all the files to the vst folder, not just dll

Thanks caoxiang and sosayweall - it works now!! (Doh - silly me, should have sussed that out myself!) In fact I found it works fine if I just choose the vst plugins folder when I export. No need then to copy any files over.

Anyway, thnx guys.
