Second workaround, you can use the Chain pattern feature combined with the Last Step + Time div per pattern in order to get that working.
- Create a pattern 1 with drum Lst step set to 12, Time Div set to 1/16
- Copy pattern to 2.
- Set second pattern Lst step to 8, Time Div 1/32
- Hold Chain select Ptrn 1, 2 in the order you want
Thanks
