I would choose:
Zadar is fantastic but you also need a fast, immediate and simple one. Dual function generator with vca's: Cosmotronic Delta-V - 10hp
Not to be used until you need something more. Almost anything: Disting MK IV - 4hp
An amazing 2 pole filter: 2hp MMF - 2hp
To add to keyboard cv, or mix waveforms: Joranalogue add 2 - 2hp
