help making acid house type bass lines

Post by sharkbarf » Tue Mar 30, 2010 2:30 pm

Any suggestions on how to program an LP to come close to a tb 303 bass?
Even if it cant be emulated mabye some suggestions on things to try to get close.

Just simple tips and thoughts are helpful as well.

I have some dance/ acid basses programmed I have to look at what I got set, when I get home.

You can always start by limiting yourself to the waveforms and filter slope of the 303. Square and saw with a 3-pole (18db/oct) filter. The nice dripping wet acid comes from added filter resonance.

Sir Nose hit it on the head. You want it to sound close to a 303, you need to strip it of it's settings until it closely reflects one.

3 pole filter
saw or square waveforms only, use ONLY Osc2 (gotta tune it yourself!)
sustain settings at 0
attack settings at 0
disable EGR release

You also may want to try automating some stuff in your DAW, particularly glide On/Off for legato glide or "slide" emulation.
I'd also suggest playing with automation for envelope amount (positive only!)

Once you get there, feel free to open up more features, but this is a general template, I made a generic "303" patch with the aforementioned settings, I tend to build off of it and then create a new patch once it's completed.

The TB-303 has a Tune knob, similarly the Osc2 is tuned against master tuning. I guess if you have messed with the master tuning knob one can use OSC1, no biggy.

So far so good. :D
A couple more questions please.
I totally understand everything except;

How can I change the number of poles on the filter? Or is that how much of the filter I use?

whats the difference between normal glide on/off and legato slide? and why would I need to emulate slide if there is a glide button on the LP console?

A "pole" is equivalent terminology to decibels of harmonic reduction per octave. 3-pole = 18db/oct, which is slightly less dramatic of a cut than your standard moog lowpass. This can be changed from the advanced settings section. Review your manual on how to get there.

legato glide is a glide mode which turns on glide functionality ONLY when you play notes legato, as opposed to your normal glide mode which is just always on. TB-303 has a feature called "slide" which employs programmable legato glide capabilities per step. By turning on glide ONLY when playing legato notes (via automation, that's hard to do live!) you can get a decent slide emulation going. I'm not sure if TB-303 did logarithmic or linear curve type for it's slide feature, but eh, close enough.

Thanks for the insights.
I had multiple breakthroughs with my Moog last night. :D :D :D :D :D :D :D :D

I lost my manual. They are $20 on the moog site WTF?
Im sure I'll figure it out.

As far as glide/slide I am controlling the moog via midi with a Machine Drum. is there a CC# for glide? I could turn it on/off for specific notes.
Other wise I use Ableton live how would I automate Glide.

manual: http://www.moogmusic.com/manuals/LP_S_UserManual.pdf

glide on/off cc is 65, find all cc params on page 43 of the manual.

happy acid making, share your results!
