Bo Johansen makes VST instruments in Denmark. Since 2000 he's been trying to sell his two products - a synth called Impulse and an organ-simulator called Organ One - through his website. A few weeks back he dropped the prices to €24.99 and €19.99 respectively. Now he's given up charging altogether, and they're both freeware. They're both well-reviewed bits of software, but there are just too many synths out there, as a quick visit to KVR always shows.
