i've just started recording some songs recently. teaching myself to use abelton. so i've got this old sansamp bass DI that i've been trying to record my guitar with. it sounds pretty good until about half way through recording a track, i get this loud electical static noise. i made sure everything was grounded, tried a different guitar, cords and still the loud crackle will happen every time. when i record my sampler, it never does that. the same with keyboard. i tried my amp and lined it straight into the mixer, but the same thing will happen. any ideas why this is happening anyone?
