Hi,
Just because it seems like it’s going to be a bit longer since renoise can be used in a tighter resolution… perhaps we could have a split bpm box as a substitute?
Most of us use eiher duplicated tempos or BPM’s multiplied by four. So there would not be need for more than a division of 2 or 4 in that box.
I personally find it a bit difficult to use delays or LFO’s in the plug-ins with bpms such as 620 etc. That’s usually because many presets for synths have LFO’s that are tempo synced or delays or other settings that get screwed totally… 
peace…
