My suggestion as in the topic. Is it likely to be implemented at all?
Great work anyway. Can’t wait till 15th of January for official release of Renoise 
many of us who are verbal about it do want this, i believe the precision we would require for this is not available in the current implementation. midi would not allow the precision without some form of snapping to beat, which wouldn’t really be that useful to the idea.
as for is it to be implemented at all, anything is possible really.
Isn’t there some kind of increase/decrease value midi command which could be used with endless rotary controllers?
Automation is the way to go!
the pitch wheel has some more resolution, and you could also use two MIDI messages together in order to have more precision, but in my opinion there is also other problems which I have shown each time this suggestion has been proposed:
1] what to do with multiple samples instrument (which may be multilayered in the future)
2] what to do with stereo samples
you could of course reply that this feature should be available for mono, single-sampled instruments, but this is quite an hack.
