Combine signals in Scriptnode

[DanH]

Is there a node which can combine two signals in scriptnode? I have a chain creating the signal / value I want but I want to be able to subtract from that signal with another signal

[Matt_SF]

@DanH You can math.mul by -1...

[DanH]

@Matt_SF you mean have it in series?

[DanH]

@Matt_SF I think PMA is the one here, what I'm trying to do is way more complex than the question and I'm trying to Galaxy-brain an idea into life!

[Matt_SF]

@DanH it depends on which type of signal you want to invert. Audio : mul / modulation : pma indeed

[DanH]

@Matt_SF modulation.

[Matt_SF]

@DanH to invert a mod signal with a pma node, simply set : add(+1) and multiply(-1). Now the value parameter is inverted

[ustk]

@DanH @Matt_SF Or use a bipolar

[DanH]

@Matt_SF @ustk Thanks. So I may as well spell out what I'm trying to achieve. I have a gain knob set to +/- 18dB. I also have a mix knob (scale 0-1).

When I begin to turn the mix level down I want the Gain level to begin moving towards 0dB (bear in mind it's got both positive and negative values). A level of 0 on the mix knob should reflect 0dB.

Does that make sense?!

@DanH yup, exactly what the bipolar node is there for:

@Christoph-Hart aha, very interesting, thank you I will give it a try now :)

EDIT - Works great, wish I posted this post in the morning lol!

While you're here did you see my post about the stock LFOs in FX Plugins not being quite tight?
