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!!
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 :D
hi contralogic,
i love feldspar so much. can you make available a 64-bit version of it?
please, please…
I can’t make a 64-bit version at the moment, due to it being made with Synthedit – maybe in the future it will be possible, but I don’t know how soon.
This plug-in and other plugins you can use for commercial purposes?
Of course! Just don’t sell or re-distribute the actual plugins themselves.
Thank you very much, Chris! I am very happy and thank God that there are people like you!
One of the best cheap virtual synths ever! Will you update Feldspar in future?
Sounds great! Looks good for a free synth. I really like the wine lead.
