Hi, I only just got Legend and am completely new to this rack extension, so apologies if I'm touching on a known issue, but I couldn't find anything about it online.
In reason, I tried connecting an external LFO (coming from a Subtractor, I'm still on Reason 7) into the "Tuning" CV input of Legend. But unless I'm very much mistaken, Legend only responds to the top part of the LFO curve. The bit that travels from 0% to 100%, but not the bit that travels from 0% to -100%.
It's most notable with Subtractor's LFO set to triangle waveform at a rate of around 40.
