i used to use the lm-4 but this is what id been waiting for. Great for the typical 808/909 stuff but also comes with alot of more expirimental sounding presets. And obviously as its a synth you can come up with your own stuff to your hearts content! As for cpu, with me (p111 700hmz) its been great, i never have to worry about getting drop outs with it. Not sure if i can think of any bad points...ummm
At the top of this page, just beside the picture you see a link "Product". In almost all the product KVR pages it drives directly to the product page in the website of the company or of the developer.
Sometimes the link is dead. When it occurs you can tell by the link "Developer" just under the link "Product".
And if this second link doesn't work either... it means that the website itself is dead. And that... if it was the website of a company it is generally a very bad sign. But if the product was a shareware or a freeware it remains then two possible solutions:
Search by using a web search engine (Google, Bing, Yahoo...).
When the product was freeware, very often you'll find easily in the forums someone who knows where to download it, or even who has it and who will send you the product or upload it somewhere and give you a link.
