hey guys, im failry new to the sp 404sx

i had many samples on it, and one day i went to add a few more, and i have a 1gb sd card, and i only had about 300mb of sound on it. so i just formatted my card once again, and backed up all the samples on my mac, but when i try to import them all again, it says FuL!! and only one sample goes through, now i have tons of empty pads and i dont know how to fix this,

if anyone knows what i could do, it would be SUPERSUPERGREATLYGREATL+HHYYY APPRECIATED thanks all!

can you sample with the rca inputs? you may need to record each sample onto pads with the rca input. hope this helps.
