you can add 0Exx commands into the effect column, and Ex commands into the volume column. i think 0Exx commands will affect every note on that corresponding row, and the Ex command in the volume column will affect that particular note only. for fast snare rushes/drills use lower values (e.g 0E01 will retrig like a woodpecker, 0E02 a bit slower… but this is all relative to what speed your song is… as heiseken highlights in this thread - https://forum.renoise.com/t/idm-cheap-trick/20957 )
