I do but then I have a modular synthesizer so I have no concept of presets
I occasionally do, although I rarely directly attempt to "synthesize percussion" or something like that - more often than not I just end up with something that ends up fulfilling a percussive role. Then again, most of my songwriting process for purely electronic stuff consists of wandering around in the sonic landscape until I stumble upon something interesting...I have preset-capable synths, but practically never use any presets.
nice man! i just started learning how to synthesize them myself...am getting better at it and in due time i'll be making the perfect kicks...all tuned to the key of the track
which synth are you usiing? i use ultrabeat that comes with logic...
dead mother of god that looks complicated haha!
