For me, much of my setup was centred around synth sounds, but since getting my keys chops to a reasonable standard now I feel I’ll do all that stuff on keys. (The exception is the FI as it is a synth and I’m still heavily involved in its development.) Hence I’ve shifted a bunch of stuff that I was using to do synth sounds.
I definitely enjoy the process of trying stuff out but seem to have moved onto bigger toys with synths. Still, I’m trying to look at what I’m using to make music versus what I’m just using to muck around with. I’m really trying to pare down to what I’m most likely to use regularly and for bass, aside from the FI, that’s likely to be envelope filter, phaser, octaver and a preamp. (The delay and reverb stuff is good in conjunction with the synths. I still need to get my head around compression.)
Oh, and regarding analogue envelope filter, wait until you get your hands on the thing I cannot name yet, it may well change your mind. It really is that good.
