Feldspar download seems to be unavailable and the site occasionally comes to a halt. Nevertheless, much appreciated
The download should be working OK now.
Thanks for giving this away for free! Considering it’s age (and that it’s done in SynthEdit) it has some really nice sounds in it. And there are a lot of extra presets…
Very glad to see Your page again and the great Feldspar too !!! Long life to Your site !!! your Feldspar is a super synth !!!

Thanks a lot for giving this synth for free!
Hello !
Very much for a long time, I bought from you Feldspar.
Now I pass on 64-bit system.
It will work in 64-bit?
It is a pity that it is impossible to contact you…
Please write to me on a mail
Thanks!!
As far as I know it should still work fine on a 64bit system – but maybe it will depend on the host you’re using?
windows 7 64 bit, crashes FL studio whenever I try to use it.
Hey love, Update you stuffs here
Get to work, because if I work, you work. Ill start ranting at you
