Aira Modular :*what are the Logic types ?


In all Roland Aira modular, you have a virtual module called Logic operation described as such :

This module takes two input signals and outputs a choice of one depending on one of eight mathematical operations. This is great for creating rhythmic patterns by combining two clock signals, or to add some variations to a sequencer pattern by combing gate signals. Experiment with CV signals – even audio rate signals and take a walk on the harsh side!

It makes a harsh fuzzy distortion, but the 8 operations are not described anywhere.

Has anyone ever figured what they were ?

Thanks a lot !

It's interesting to see these in there. The manual I was just cruising says that they're only for audio signals. Logic is typically used on triggers and gates, but Aira doesn't really have the room or advanced enough modules to spit out enough gates and triggers to make this into a meaningful/useful signal. I'm guessing because of the manual typo, they intended this more for screwing with waveforms.

Yeah, never tried them with actual gates - someone on muffs had said they might be implented as bitwise operations, rather than the usual high/low "gates" you'd expect...

Thanks a lot, I probably looked over the document because I thought "logic gate was something else"

However : why does it sound like a fuzz ?
