Would -20 (currently -30) be enough?

It 's not easy because we will have to update the firmware of all TM FX hardware. So this will not be done quickly, but soon.

Is there any chance of ever seeing 2 sends to control the FX ? this would help live mixing a lot to be able to run a verb on snare and a delay on vocals with independant send controls..

I backed off the preamp gain on some of the aforementioned drum inputs (I wasn't clipping before, just have more headroom now), and the -30dB threshold is usable, but would still be happier with the proposed -20dB threshold - especially on the floor tom.  Take your sweet time on this

RE ebulb's comment:
As a simpler and way less elegant tradeoff:  What about adding discretely assignable inputs to the Reverb and Delay blocks (similar to the output assignments in the CR).  The Reverb and Delay would default to the integrated Aux Send bus as they do now - but then have the option of assigning their block's INPUT to a MADI Output (that output's submix is now your "Send #2")?  You could even EQ and "gate" the send if you want with the output channel's EQ/Dynamics   (common for snare verb sends)

Both Reverb and Delay could technically still return to the common FX-Return bus in this make-shift solution - or maybe have the returns assignable to input channels in TMFX for discrete FX-return control (don't want Snare Verb in the Vox Monitor, etc).  You could then EQ the FX-returns in the input channel as well!

This would allow much better utilization of the two independent effects blocks.

Like I mentioned before - just tossing stuff out there and seeing what sticks.  I'm thoroughly impressed with TMFX's current feature set
