The problem is that you can’t actually follow CLA’s workflow as he demonstrates on the vintage gear. Each of his reverbs and delays were set to separate return tracks, so you could set the send for each one from each source. E.g. I can crank up the send level of vocal into the slap delay specifically and leave the send lower for things like drums if I want. Because of the plug-in architecture (maybe a limitation of how VSTs work?), you only get one send channel that feeds the plug-in. That means I get one “setting” that has to work for everything I feed it to or I need multiple instances of the plug-in to tweak for each instrument I’m sending and then somehow have to keep those settings in sync. For this plug-in to truly follow the workflow CLA demos in the promo videos, this plug-in would somehow need to operate as 8 independent returns with the ability for the delays to also be sent into the reverb returns.
NOTE: I’m NOT talking about having separate effects settings for each instrument. I get that the point is to keep them the same, but I do need to control how much of each instrument is being sent to each effect.
