But…
you can try this…hold FUNCT and press the unlit MUTE button of the silent track…this way (keeping held the Funct) you get prepared to unmute it…
then rotate the two Macros towards left,if i remember correctly the Macros should snap immmediately to zero if Funct is held.
When the sound gets where you need it, you can leave the Funct button so you can unmute the Track.
In this scenario, of cours, you have only one hand to bring two Macros to zero…
Sometimes on Elektrons…you need ninja moves
