Journal: 1 Mar 11 – Lurker, AC Toolbox basslines and iPad hex controller

Programming Notes Some experiments with creating random bass line sections in AC Toolbox lead to some fairly predicable results.

The rhythm sections should be non random if you want to maintain the standard bass line feel. The pitch values need to be constrained though I tend go for more variable pitches than the single note bass lines. The AC Toolbox random distribution functions generally have a low and high limit values, these and to be kept with in one octave or less, and a value for variability which should be kept low.

Pitch examples:
(1/f-value 5 32 48) – 5 is the variability, 32 is the low pitch 48 the high pitch
(cauchy-value 38 20 32 46) – values around pitch 38 with a spread of 20. Low value is 32 high value is 46
(weibull-value c2 9 1 c3) – C2 is the threshold, 9 is the spread, 1 is the shape and c3 is the maximum value

To get some movement, a shape (actually a line) converted to a stockpile can be used instead of values eg
(1/f-value 5 updown-stk 48) – updown-stk is a rising then ascending list of values between 32 and 46.

Reaktor: I was trying out iZotope’s “Stutter Edit” which I realise is a lot like the Reactor ensemble “The Finger” which I already have. I don’t like using either which got thinking out distortion and drums and had me trying out “Ohmicide” by Ohm Force. The distortion is great but in Reaktor 5.5 there are some good effect plugs including distortion with the Electronic Instruments Vol.1 collection.

This in turn took me to “Lurker” which not distortion but delay lines mixed with additional samples to modify the audio and it sounds great. I tried hand crafting presets but the easiest way is to use the snapshot random, morph or merge functions top create usable snap shots. You can also grab additional samples and add them to the table for merging with the external audio. (Just remember to turn up the external audio which often off by default)

iPad Controller: The Hexachrom iPad app is fun to use once you establish a connection using Oscullator, which is an additional purchase if you don’t already have it. I seemed to have problems with the connection to start with and then it just worked. Oscullator does open up a new world of controller possibilities with iPAd WiFi of which Hexachrom is one. Nice and harmonic.
