I got the idea to use BV512 to make a stock combi that performs a similar function to what "track spacer" by waves or the Carve EQ RE does. If you aren't familiar, essentially it takes in a sidechain audio and performs a multiband ducking of different frequency bins across the whole frequency spectrum. This makes it so the main signal source ducks all frequencies being used by sidechain and prevents mud or other kinds of frequency conflict. The best part is if the sidechain audio is in a rest or goes silent the signal source returns to flat EQ. Less automating guitars fighting with pianos
How to use the combinator:
Connect a mono sidechain to the modulator source for the first BV512 and your audio as the combinator's input.
- Scale Cut - Scales the amount of ducking that will be applied. This should always be dialed on a track by track basis to "whatever sounds right" similar to how you would dial in any cut or boost.
- Db Offset - where "0" is on the EQ. 89 is 0db but you can move it up or down. This will have the side effect of making cuts more or less drastic as a side effect as well as any coloration associated with the band count.
- Dry / Wet - Self explanatory hopefully
- Attack - How quickly a band gets ducked
- Release - How quickly a band stops ducking when the frequency content disappears from the sidechain
- Band Count - 4, 8, 16, 32, FFT; as stated in the reason manual, there's only 16 CV outs on the back so if you select 32 or FFT each output controls more than one band. I usually just dial this to whatever sounds the best.
- Hold - applies the hold button to the inner modulator BV512. This will lock in the frequency band ducks for that moment in time. Useful to prevent pumping when maxing out release isn't enough.
- Volume - Master fader
