Yes but this means I'd still have to adjust the timing manually on both plugins to keep everything in sync so would only be useful if a pre delay of more than 370ms was needed to make GainRider2 work smoothly. It has only just been released so I'm not sure how often I would need to go past 370ms in practice since it seems like quite a long lookahead anyway.So are you saying that you are able to manage GainRider2 pre-delay values beyond 370ms with Latency Fixer plugin?
Latency Fixer is free btw so you could test it yourself if you thought this was an avenue worth pursuing.
