I played around with Valhalla DSP's excellent Supermassive plugin and wondered if there was something similar in Reason.
I started playing around with an effect chain in a Combinator to try and mimic that huge larger than life type of reverb sound.
I present to you the result. It's not exactly like Supermassive, but it's pretty darn sweet, in my humble opinion.
The archive contains an insert effect Combinator, and a simple patch example Combinator. Be wary of the levels if you increase the DRY/WET level.
Some notes:
Chorus - Some sounds might benefit from Chorus being disabled, like piano for an example.
Delay Modifier - Changes delay time and mod settings (subtle).
Delay Feedback - Simply enables or disables it, depending on your needs
Experiment by opening the Combinator and loading different chorus patches into Quartet.
Enjoy!
