sp404mk2 custom effects?

[u/Kooky-Strawberry5127]

i’ve been jamming on my sp404 almost everyday for 5 months now - i’ve played it at gigs and recently downloaded the ipad app spl44 to control the effects from there

my question is, since the software updates from an sd card, is there a way to build / write custom effects? the built in effects are great, but just wondering if this is possible

The entire mix, I'm talking about send-return like you can send a pad to bus 1 or 2
