Fx unit for Blackbox

[Dansterism]

Can anyone recommend an FX unit for the Black Box to go into.
maybe similar FX to the Roland SP 404

When I think of SP-404 FX I think DJ style FX. I don’t think you can beat a Korg Kaoss pad (you choose the model) for that kind of thing.

Yes I was thinking perhaps the Kaoss pad. Any experiences with using an iPad for FX?

I have used the Korg KP3, iPads, iPhone, SP-404 mk2, Korg Electribe2/2s, Akai Force, Ableton/BitWig, and Zoom G5 guitar multi effects pedal as master effects, and for sampling/resampling into the BlackBox.

Could you share your setup with an iPad and which apps you like for FX and your experience
Thanks!
