How can I reverse the polarity in FL studio 12? While I was watching this video, he reversed the polarity of a track in the mixer with just one button but I can't seem to find this effect in FL studio 12. Any help is much appreciated, thanks in advance. Save hide report. For those familiar to FL studio, this is accessible there as a tickbox ('Reverse Polarity') in the SMP tab of the channel settings menu. This should literally invert the wavefront of the sound, an effect that the ear can't recognize, but can be used very effectively for signal extraction, for instance when one wants to extract the voice part. It sounds like you have a polarity issue. There are two types of midi sustain pedals:-. sustain pedals with polarity as '+' (positive). sustain pedals with polarity as '-' (negative) But if you have an M Audio SP-2 sustain pedal you can change the polarity. I own that pedal and there is a switch on the bottom.
OH!!
sorry
Inverse Polarity is what you said... doesn't matter
does this help:
inverse polarity' in the sense that you're describing is known as 'Differential transmission' and simply means that you have two wires with opposite voltages on them - i.e. when one wire has a high voltage, the second has a low volatage, and vice-versa. The technical answer is phrased a bit differently - rather than referring to a high and a low voltage, what you're really measuring is the voltage difference between the two wires. Imagine hooking a voltmeter between the two wires - a '1' may be transmitted by having a positive voltage appear on the voltmeter; a '0' may be transmitted by having a negative voltage appear on the voltmeter. It's really no harder than this.
The reason is relatively simple - every wire in the universe is also an antenna, and picks up stray signals. You can imagine that this can be a huge problem when you imagine running a 100 meter length of twisted-pair ethernet cable. That's one big antenna. So, how do you eliminate the stray signals?
You start off by twisting the wires together. If you open up any modern communications cable (USB, Ethernet, Firewire, etc) you'll notice that the data wires are twisted around each other. Because of this twisting and the consequent extremely close coupling between the wires, almost all of the stray signals picked up by one wire are also picked up by the other one. So, now you have two noisy signals rather than one - doesn't seem like we've gotten anywhere, ehh?
Well, now we do some mathematics. Imagine the signal in one wire is (S+N), where S is the original signal, and N is the noise it's picked up. The signal in the second wire will then be (-S + N), where the signal is exactly the opposite of the first wire, but the noise is the same (it didn't get inverted). What happens when you subtract the second signal from the first?
Result = (S+N) - (-S + N)
Result = S + N + S -N
Result = 2S
What happened? We ended up with twice the amplitude of the first signal, and all of the noise got cancelled out!
Reverse Polarity In People
As to how you generate a signal, it's pretty easy. In order to transmit a signal down a cable, you normally run it through an amplifier inside whatever electronics it starts from. Note that in this sense, the 'amplifier' is a tiny circuit, not a big black box with a dial that goes from 0 to 11, though the big black box probably has a bunch of the tiny amplifiers.
Anyway, in order to generate this differential signal, you run it through two seperate amplifiers - one an Inverting amplifier (google it, or simply accept that this exists), one a non-inverting amplifier. Presto, the two outputs are attached to a wire, and you have a differential signal.

I didn't write that BTW
