Bitwig Preset Sequence Selector HY-MPS2 free
Select which sequencer is active using the select-4 modulator in the sequence selector, I recommend mapping it to a midi controller. Change octave and semitones for all sequencers using the transposer. This is the free version of MPS2 and I recommend the full version.
