I reckon a simple saw wave, doubled up with the sub osc to beef it under, and then getting the settings right with the Filt Env is crucial. You can give the sound an almost percussive, punch quality with the filter decay.
Sometimes also adding a tiny bit of envelope pitch through the Filter Env can also add a bite to the sound.

And then, quite important I find is running it all through the right filter saturation mode... Medium is always good, but you can always push the input
to add some more interesting overtones to that filtered bass sound.

been messing around with a few of your ideas, but i still havent come up with a bass on the virus that im happy with... i dont seem to be able to get rid of a crackling sound... dont really know whats causing it :S any ideas?

hi

i use the ti for psy bass........

i've been tweeking my settings for a few months.....

i'm very happy where i'm at atm.....

i'll check to see what everything is set at when i get home frm work and let you know........

i had the crackling sound too......its gone now !!!!

2 days later....and beer in mind..

....i dont know what i'm doing kinda sometimes...

i tried psy bass on my juno, korg, plugiator, lead2xnord, with not much luck mainly coz of the oscilator waveform starting at a different point each time the synths were triggered via midi. Syncing the oscilators on the nord helped a bit...but no cigar... (you can see all this happening if you record sum and zoom in to the start of each note...) Of course this is a non issue if you dont trigger via midi and like samples instead!

now onto the ti.....which has oscilator phase init!!!!!

2 saw oscilators, oscilator balance +63
no sub, phase init : 96
punch : 127, sync ON

Analogue boost intensity : 127
low eq boost around 80 hz +5db

LPFilllltttttterrrrrr
filter balance -63
filter routing : serial 6
saturation : off
key follow + 39
env polarity : positive
key follow base : A#0, or B0 or G#0 or :)

filter ADSR 7 , 27 ,127 , 12

amp ADSR 56 , 55, 127, 20

sustain slope 0 on both

cutoff : 69 res : 0 envelope amt : 68


Because of the long amp attack time i have to slide my notes a little bit back in the sequencing......this is what got rid of the crack that shat me though! ha ha

the note length i use seems to be a little less than 1/32nd notes in the sequencer......note length seems to play a big part?!

SIDECHAIN COMPRESSION WITH THE KIK IS LOVELY, RELATIVE VOLUME BETWEEN KIK AND BASS AND EVERYHTING IS SO IMPORTANT...

obviously everything with sound design is personal and is tuned to taste......

this is what i do .... i hope i helped in some way..

cheers

thank u very much for that rotten, its much appreciated! :) i'll check it out next time im writing and let u know how i get on! i wont just be lazy and use your sound tho, but should help me understand how to get to a nice starting point for thurther tweaking!
