Demented

Hello everyone,
First off, I'm new to the community so, hey how you guys doin?
Anyways, I was previously in a Metal/Death Metal band and I quit because I wanted to do my own thing. I play guitar, but Ive really been wanting to get into a more experimental sound.
I have never owned a Synthesizer, and I was wondering if you guys could help me find a good one that isnt too expensive. And maybee give me a few tips on how to set up and get started creating my kind of music.

The sound I'm looking for:
A mellow, spooky, very experimental sound. A very eerie sound. Also, I will go back and add guitar with it.


Also while I'm here, I was wondering if anyone has any good tips on recording devices? and what kind I should purchase. Me and my old band had our own little set up for our recording, and we used a cheap recording mike, which wasnt the best quality in the world... at all... And, I would like to use computer software to record. Know any good programs???
