Hey guys, I'm Indian and I'm pretty cheap so I've never paid for plugins or VST instruments (yet) and I'm always on the look out for something free, so I thought I'd list some of the stuff that I've found and if you guy's have something that I haven't listed we can share links.
Variety of Sound: I found these plugins today and I'm not sure if anyone's used them before but I was so impressed by how good they look and sound, their epicVerb and FerricTDS are the best plugins I've heard out of my computer (I don't know how it compares to stuff like Waves and others though).
Kjaerhus Audio Classic Series: I found these from DJ Laidback Luke he mentioned them in some weird studio tour in his home, These are pretty alright I like the Auto-Filter.
ReaPlugs: I found these today as well but I haven't tried them yet, these are the plugins that are found in Cockos REAPER, I'm excited to try their Multi-band Compressor cause I've never really used one before.
Molot: This is a Russian Compressor which I haven't used yet to be honest but its looks great.
Elektrostudio: These were first free synths that I had found, I really like the Model Pro its like a replica of the Moog Prodigy its pretty fun to play with.
MinimogueVA: This is one more thing I found today, its a replica of the Mini Moog and its so much fun and sounds great too.
Formant Classic: I found this synth last night and its pretty good, the guy who made it says that its good for learning how to use synths and stuff.
DiscoDSP HighLife: I found this through the Game Audio Tutorial book and its so much fun, its a Sampler, I like to put in recordings of my brother farting and make melodies out of it lol.
Vocov2: This is a fun Vocoder which is another alternative I use to make music with my brother's farts.
TS-808: Ohh snap this is another thing I found today, this is obviously a replica of the Roland 808 Drum Machine, I've only played around a little bit with this but from what I've heard so far its really good.
So anyway I hope this doesn't make me look like a super duper fantastical cheapo and also since I'm still a beginner in sound and can't really help many people on here, I hope at least these can help you guys.
