Wee little sounddesign trick: DC samples

hey!
Rytm has this symmetry control in the master section, which lets you shift the main output audio up/down, which can lead to pretty interesting results with the master distortion. I.e. with positive symmetry offset, the positive peaks in the signal will hit the distortion harder than the negative peaks, resulting in some interesting harmonics.

So… the individual voices have an overdrive before the filter. What would happen if you add a DC offset to a sample (essentially same result as the symmetry control), and then play with the voice’s overdrive?

Tried it last night and it works! Did only a quick test with a sine wave which was dc-shifted into the range 0 and 1 and compared with a regular sine with amplitude peaks -0.5 and 0.5.

When using overdrive on that sine, it sounded completely different than the regular - will post pics & sound later.

Think there might be a small universe of new sounds to be explored with this. E.g. you could use a sample which is just a fixed value at max volume, and you could use it to add dc offset to the analog synth of that voice - again, hitting the overdrive/filter/amp asymmetrically. Not sure what’s gonna happen lol.
Also, control-voltage-like “LFO” samples should work for this as well…

Great tip, thanks for sharing. Be interested to give this a go.

hm ok seems in most cases the result of a DC-LFO kind of thing mixed with an internal synth is mostly just amplitude modulation of the synth…

here’s a 1Hz sine wave LFO sample:

and here’s a 1 second DC offset (max amplitude):

some interesting things emerge with the bit rate reduction - (mainly just clicks tho)

haven’t tried yet with DC-offseting regular samples containing complex sounds…
