double your bpm = twice as much resolution
well we know all why this is not the solution.
Because you also need to double the speed-factor 
Arranger.
What exactly means “A routing enviroment” btw?
where is PDC? 
votet for 1st option though, since it’s the only selectable poll-option i actually do miss of those which are listed here.
even though “routing environment” might do the same to my undestanding, because sending midi notes to FX implies a overhauled routing system to my undestanding, so option 1 seems to be implied by option 2 (?).
Something like a modular patchbay where you can interconnect MIDI / AUX and slave options like ReWire.
If there would be one extra panel called “communication” that allows you to connect (vst) instruments and / or effects internally with eachother and / or connect them to external hosts through MIDI or ReWire this would solve a whole lot of problemswith VST effects that respond to MIDI messages or VST-Instruments that can or have to exchange MIDI messages to other VST plugins (Like the Melodyne plugins).
Possibly in 2.0 or 2.1
I’d need Latency compensation above all. Apart from that it’s all good imo. Some workarounds necessary for certain results (side-chain), but I don’t mind those 
.
PDC(which will come in 2 or 2,1 huuuurraaa)
but i voted for the first one,even if i would like to see the other features too
If you are all, then okay… but please explain why that is NOT the solution.
i think its because a lot of the users have already voted and posted their fav. feature and written down most of the ideas.
‘sometimes’ its like everything is repeated.
a routing environment = modularity, gets my vote.
Hold your horses, that was not a promise but my guess.
didnt mean to sound over enthusiastic,i just hope it comes in the near future 
beat slicer
if i could change my vote,i would probaly have voted for the routing enviroment
routing environment definitely. the more i use renoise the more i think… hmm now if only i could attach any output parameter to any other output parameter. it would open up insane possibilities…!
sound generation ala mathematica.
instrument & loop point automation.
most importantly a renoise mantra on:
“how to stop wanting, and start doing.”
multi canal vsti
midi vst
sidechain effects
its some kind of routing
i am for routing
edit: oh, after reading the definition of “routing environment”… Definetely got to say: “Routing environment” =)
