How to multiply frequency?

#1

Hello all. I know it must be easy, but I can't seem to be able to figure out a good way of creating fixed ratios between oecillators. I basically want to multiply one oscillator frequency ba number. I can do it with the multiplication and an integer, but when I use the ctrl/dial p multiplied by the control blue output of a sequencer, the dial acts as an attenuator with the maximum being 1. Is there a dial that I can use to multiply by number greater than 1, but including fractions?

I'm sure I'm just a bit rusty, but I can't seem to figure it out today :frowning:

can you not just adjust the dial on the oscillator itself and detune it that way? or do you want a fixed offset? as in, two oscillators, always 2hz apart?

Oh yea, that would work. I was thinking of a dial where you could put in 2x, 4x etc as ratios of the original frequency - like on the yamaha fm synths. If i dialled it in on the oscillator it would be fiddlier to quickly change ratios over different oscillators.

i did octave switch for this oscillator contrib/phi/slowsine osc

@geecen

Did you try the math/gain object? If you run a regular dial through this one, it lets you multiply up to 16 times :slight_smile:

I was using the math * with red inlets - is there a separate one for gain? If so, that sounds like the ticket.

Yes its a different object called:

math/gain

Aha! There we go. I've bee using PD more than Axoloti recently and couldn't remember how it worked. Thanks.
