i have a play acoustic (last firmware) When i go to the advanced options on the bodyrez in the compressor settings attack and release only go from 0 to 19 ... what do those numbers correlate to? are they miliseconds? I really hope not because having just 0-19 miliseconds to choose for attack and release times doesn't seem like a smart choice.
On a guitar (or in general) compressor, attack controls how much of the "initial attack" on the sting is articulated from min(0) to max(19). So if you're strumming you may want to set it toward a minimum setting so your strumming sounds more evenly, but if you're chicken picking (like country music players do) you may want to set it toward a maximum setting so each note pops out.
Release controls the decay time of the note you play. On min(0) setting, the note decays naturally but on max(19) setting the note is sustained.
So if you're playing Van Halen's Cathedral (from Diver Down) for example, you may want to set the attack to 0 and the release to 19.
It would sure be nice to know the actual or estimated milliseconds as that is what a lot of us refer to since we compare what we find useful in, say, a VST or RTAS plugin and would like to start with a close setting to what we already know works with a particular vocalist or genre. Can the milliseconds reference to the 0 - 19 be unveiled somehow? Even if TC simply gave us a general reference chart.
Hey you guys! I was also asked to dig into this by a coworker in support, I'll share my findings with you as well So the compressor algorithm was actually developed by TC Electronic, and because we're such good buddies they let us use it in our products as well. The parameters for "Attack" and "Release" are not milliseconds, they're basically positions in a list of numbers that you're choosing from. In hindsight it seems weird this info wasn't in the manual, but I guess we figured people would use their ears instead of their eyes. Anyways I've attached a table showing how the values you see in the UI relate to the internal values for Attack and Release in the compressor. Cheers!
