Phase inverter combi for Reason

For some reason (haha) there is no "utility" device in Reason, and if you need to do phase adjustments there's no obvious way to do it. Phase inversion comes in handy if you're doing routing with devices that introduces a delay in the audio processing. I don't experience this often in Reason, but doing fancy stuff with sends is one such case. Say you're compressing a sort of sidechain on a send (this happens :). To prove it I'll link you a track that needed some phase twiddling to get the bass and drum compression right ;)

If you're using record you can find a handy phase inversion button at the top of the mixer. But this is primarily useful if you've got crooked audio of some sort since you can't insert this into your processing chains.

As always with Reason the solution is in a surprising place. If you route audio through Thor it can be phase inverted by using a negative value in the mod matrix. This is very easy to setup, just make an audio processing Thor as usual but stick -100 instead of 100 in the Amount section. To add a bit of an extra touch I've added routings for the button to phase invert the left and right channel respectively. This takes a slight bit cleverness by routing the audio twice through Thor, both unaltered and inverted. The buttons in Thor scale the inverted signal up and the unaltered signal down, and those buttons are again connected to the Combinator buttons (note to Propellerhead: it would be cool if you could manipulate the mod matrix directly from the Combinator modulation routing).

You can get the combi here.

Cheers!
