This is Matsuda's homepage. You can download the voicebanks there.
The first column on the left is where to download Matsudappoiyo and Matsudappoine's voicebanks. The last one translates to "garbage" in my browser, so I can't tell you what it is for certain.
The first in the list is Matsudappoiyo's voicebank directory. The next column on the left are the links for the following:
CV Voicebanks
VCV Voicebanks
Retake (Append) CV Voicebanks
Retake (Append) VCV Voicebanks
http://lllll17.web.fc2.com/poiyo-r.html
This is the link to Matsudappoiyo's VCV download list.
The title of each post should have a working download link. You can also sample the voice on the website before downloading.
Hope that helps!

Help and Advice section, that's where these types of questions go.)
