Hi,
1 – The main looper is the 10 tracks looper.$state_multiply$, $state_mute$, $state_overdub$, $state_record$ will tell you the state of this main looper.
$current_full_tracks_count$ and $current_last_full_track$ will tell you how many tracks are playing in the main looper.
2 – $current_loop_duration_ms$ and $current_loop_duration_samples$ will tell you if there is something in the main looper : {$current_loop_duration_ms$ != 0} means something is recorded and if it is not muted ({$state_mute$ == false}) it should be playing.
3 – if you load a looper in fx3 / rank 1, this variable will be created : $Looper_fx3_rank1_Record_state$ and it will be visible in the list.
If you put $Looper_fx3 in the filter part of the variable table, you will see this list :
$Looper_fx3_rank1_ActionAtNextBar_state$
$Looper_fx3_rank1_AutoFade_state$
$Looper_fx3_rank1_CrossFadeShape_state$
$Looper_fx3_rank1_Group_state$
$Looper_fx3_rank1_LatencyCompensation_state$
$Looper_fx3_rank1_MuteFadeLength_state$
$Looper_fx3_rank1_Mute_state$
$Looper_fx3_rank1_PauseMode_state$
$Looper_fx3_rank1_Play_state$
$Looper_fx3_rank1_Record_state$
$Looper_fx3_rank1_SelectionIn_state$
$Looper_fx3_rank1_SelectionOut_state$
$Looper_fx3_rank1_SpeedFloat_state$
$Looper_fx3_rank1_SpeedSemiTone_state$
$Looper_fx3_rank1_Sync_state$
$Looper_fx3_rank1_Synchro_state$
$Looper_fx3_rank1_current_length$
All of those variables describes the fx3-rank1 Looper state
