oukai, kadangi Cosmosis aka Bilbo Baginzas sugalvojo uz babkes dalintis savo patarimais (32 EUR) :P wtf... tai copy pastinu senais laikais is jo nucypinta info basica apie basslin'a 8)
paparstai ir su bajeriu
1. "The Oom-Pah" - The original Teutonic knee bender. Possibly originating at the Munich beer festival - spookily enough features on many "progressive" German Trance records
At it's most basic, it consists of a quarter note bass note on every offbeat of the bar. That is to say if a bar is subdivided into 8th notes, then the bass note would come on every other beat; e.g on 2, 4, 6 and 8 while the kick would sound on 1, 3, 5 and 7. Add your own variation by e.g. patching filter to velocity and tweaking velocity....varying the note length etc... moving to another note (shock, horror! at the end of a 2 or 4 bar pattern - which also applies to the following lines too...
2. "The Gallop." Consists of bass notes on these 16th note subdivisions in a bar: 3+4, 7+8, 11+12 and 15+16 Yee-harrr!
3. The "Doof-a-Danga' Consists of bass notes on all 16th note subdivisions in a bar except on the beat - that is to say except where the kik lands; so omit notes on (16th. note subdivisions 1, 5, 9 and 13) Popular in much of the so called "full on" style Trance and Israeli Trance in particular...
These are your basic patterns. You can play then straight, but perhaps better to bring your own compositional skill into play by mixing them all up to create an individual line, varing some notes for accents. Another idea is patch the velocity to the filter in the synth. and adjust the note velocities (by small amounts) to create some accents, It's up to you.
Remember; whatever sounds good, is good.
Another important tip is that you should keep your sequencer note length quantization on a 64th note resolution or less. Varying the note lengths by small amounts can quite drastically alter the overall effect when it comes to Trance basslines, making the difference between a nice, tight funky groove or a drunken punk rock band at their first gig.
Now, for the bass sound.
Select a subtractive synth (Hardware or VST)
A good place to start (and end actually) is setting the oscillator at a single saw wave. If you decide to use two oscillators, a square wave mixed with a saw wave one octave above, at around 70/30 ratio low/high will sound great.
Also, when using more than one oscillator, I prefer to hit the sync. button (or similar function - Phase Init. on the Access Virus) to lock them both together to stop any phase variation at note on, which will play havoc with the levels of individual notes in the bassline. Trust me, you don't want this.
Filter the result with a 24db low pass filter, (but 12db or even a 6db can sound cool too)
Filter Envelope: Fast to medium decay. Filter envelope sustain: zero.
Filter envelope depth: Set approx between 5 - 30% ( depends on the synth...)
Top tip: keep the resonance value low for trance basslines with this type of envelope shape and depth. From 0 - 25% res.
Amp envelope: For now keep the attack and release as fast as possible without clicks - again depends on the synth - for now, keep sustain at maximum. Adjust the release in the range 0 - 20% until it sounds nice and sits with the kik.
Set up the kick, loop the track and tweak the above parameters until you are satisfied that it all locks together nicely.
Another top tip is: Choose a kick that fits with the key, or a key that fits with the kick. It doesn't have to be the same note neccesarily, just something that sounds consonant. Then tune the kick up or down a little in the sampler until the low frequencies gel best.
