Is there a pattrstorage attribute or trick I'm missing allowing to
interpolate from the current state of a preset to another ? My problem
is that when using 'recall 1 2 )', all clients jump to
their saved state in slot 1, ignoring changes since recalling 1. The
solution I'm thinking about would be to store clients state in slot 0,
then interpolating from slot 0 to slot 2 but I just want to make sure
I'm not missing or misunderstanding one of the existing pattrstorage
functions. If I'm not, any better idea ?
