Take the cut-off (or whatever) and quantise it to have a low-step count - sync' it to an LFO, and then you'd get tempo gated type stuff. Well, actually, more "step-sequenced" type stuff.
As Juho says, imagine if you swept the cutoff knob as normal - it's nice and smooth, as Access have programmed it so that all the values 0-127 are smoothly joined together (I just wish every other synth manufacturer did this too
)...
However, if you quantised it to 128, then it would get rid of the smoothness, and it would step from one value to another at 128 different points. (Similarly like many older digital synths did by default, such as my MC505).
Having the option to quantise it further to a really low value, such as 8 (ie. 8 values/regions over the whole 0-127 spread), the cutoff knob would appear to be
really "steppy", and you'd only have 8 different cut-off frequencies to sweep across (as opposed to 128 different, discrete values - or smoothed like it normally is). So, although you would sweep the cutoff knob as usual, the actual frequencies would step/jump violently from value 0, to 14, then to 28, then 43, 57, 71, 85, 100, 114, and finally 127 - [or something along those lines]. It wouldn't be smooth between each value.
At least that's how I
think the knob quantise function will work? Please correct me if I'm wrong, if anyone knows.
