If you're planning on integrating the Mother 32, maybe you don't need another VCO, but something simple like an Intelligel Dixie II + gives you a versatile VCO/LFO, or the Make Noise DPO/STO modules. reverb/delay is great to have, whether on the rack or an effects pedal. the 2hp modules for reverb and delay aren't bad for the money/size.

Yeah I was also thinking the DPO! The problem is just the price since im pretty tight on the 3k. So I will probably have to decide between the Morphagene and an oscillator. For effects I will probably wait a bit since I am working pretty tightly integrated with my daw and I think basic delays and reverbs can are almost equally good out of the box!
