The usual process would be If you are using a sine wave, C1 = 32.70Hz and 32.7 cps (cycles per second) for your bassline. This is a constant yet not exciting bass. A kick is generated by starting at the root note OR within the key and then it sweeps down the scale and ends at a few octaves lower, example: C7 = 2093.00Hz tsweep = 84ms down to D1 = 36.71Hz. (This may sound like crap but for example sake, eq and other processes are used to clean and meld). Now you do not need to phase this as you are staying within the key and using your ears to find a pleasant sound.
Having said the above, this brings me to the kick being "faded out". The kick will always finish before your bassline is triggered. Sweeping down the scale and having the cps (cycles per second) changing within 84ms is just plain silly to try and accomplish phase alignment. So we use side-chain compression to help meld the two elements together. Automation of the volume could also be used but very time consuming.
Wow, just wow...
I only say this because, well, how long did it take someone to come up with a way to create a kick drum sound?
The really interesting thing to me, is the result you've described has absolutely no bearing on what actually happens with a real kick drum!
Is it possible that psytrance could be improved by using a real kick drum? I dunno.
A real kick drum has a fundamental frequency determined by it's construction. That frequency can be measured, and, by and large, any drum tends to sound better when tuned to it's fundamental.
Even then, there are two standout aspects to a kick drum sound;
The "thump" component, somewhere between 50-70Hz. This is determined by the fundamental tone of the drum, and, suffice to say, 63Hz isn't a bad EQ slider to find the right level. Thump will benefit from upwards harmonic reinforcement, and has sustain, out to about 750ms at 30z, 350ms at 60Hz.
The "click" component, somewhere between 2.5 to 4K. This is created by the bass drum pedal striking the drum head, and defines the bass drum note, letting it sit in a mix. To much click (as well as over compression) makes it sound like a death metal bass drum, not enough produces an undefined muddy bottom end. The click is short, to around 100ms.
I'd be really interested to see what you thought of a kick drum sound generated by using a 3K short duration tone as a sidechain trigger to a 60Hz sine wave...
