ldub_NEW
adds data to the content of a table,at inlet pos (in fraction of the table's size).feedback controls feedback amount. set the length of the fade-out period with 'release', the length of the fade-in of the recording with 'attack'.
Inlets
frac32buffer.positive index in fraction of table size
frac32buffer audio in
bool32.risingfalling overdub
frac32.positive feedback amount
frac32.positive recording fade-in time
frac32.positive recording fade-out time
Outlets
bool32 recording state with fade-out
Parameters
frac32.u.map feedback
