I’d love to see the option of using an expander or ducker. Perhaps as alternate choices for the gate processing slot?
A ducker would be especially nice. While side-chain compression can approximate a ducker, there are certain cases where a true ducker is required to reduce level while preserving the original dynamics, or where a compressor/ducker would be employed at the same time.
An example would be bass guitars. The overall instrument benefits from compression, but it may be desirable to additionally sidechain some ducking relative to the kick drum beats to allow the kick to really punctuate.
Expanders would be nice to reduce the hums and buzzes of certain sources (I’m looking at you, guitar amps!), without the brutal binary open-close nature of a gate.
P.S.: We’re eagerly looking forward to using the iPad app with our S5000/DM48. 🙂
