Hello community!
I need your help to complete my setup (you can jump to the end of the message if the emotional part bothers you

)
I want to make music since long time, so I've bought gears and quit the job. Now I'll have less money but more time music!
My project is vastly based on improvisational live looping, but with some prepared samples too.
At same time I will produce music at home.
I have many influences and many musical wishes, so I'll experiment a lot and surf at my way through genres, but in this moment possibly many of the music will be inspired by techno/electro and minimal (German Style), with touches of dubstep (those visceral basses!).
My actual setup is (details in my profile):
-my voice (singing, beatbox, overtones)
-Elektron Octatrack as hardware sampler/looper
-Ableton Suite 8 with Max4Live as software sampler/looper
-Roland Quad Capture audio interface (internal clock, supposedly extremely low latency/jiitter)
-some Synths
-midi controllers
-mixers
-effects (but no signal processors yet)
My target now is to complete the setup with those MUST HAVE which by being newbie I may have not realized that I need

For example I suspect that I miss tools to achieve the typical sounds of the above mentioned genres, especially the warm round punchy kick, and the dense basses.
Maybe compressor, and some specific synth or effect, EQ, limiter, no idea.
And that's where I need your help.
Feel free to suggest all the hardware and software that may be missing in my setup, and please include also some more affordable options so eventually in the while I can buy those.
I am particularly concerned about syncing because I have read that Ableton may be capricious in that aspect, at least when it is slave.
I was watching the Innerclock System products and they are wonderful but also so expensive.
THAAAAAAAAAAAAANKS!!! A lot!
