should work fine... as long as the voltage is high enough and the signal is as long as you want it to be...
if the module's expecting a trigger/gate it's probably expecting a threshold to be reached to apply the accent and a drop below that threshold to stop applying the accent...
not sure how the velocity is done in the beatstep pro - I've never used it on mine - but I suspect that it just outputs a voltage based on the max output / the value of the velocity... and then turn off once the step is over... so effectively a gate at the level specified by the velocity value
shouldn't hurt anyway - give it a try!! - it's all just control voltage

Utility modules are the dull polish that makes the shiny modules actually shine!!!
