The usual approach here is to split the [tabosc4~] into its phase and
table-lookup parts by using [phasor~]--->[tabread4~] instead. Then make a
phasor~ signal half out of phase using [+~ 0.5] and [wrap~] to drive a second
[tabread4~]. Window both signals with e.g. a raised [cos~] window and you're
set.
It's the approach taken in many of the sampler-examples in the 3.audio.doc
sections and described in detail in Miller's book, which you can read online.
(I consider it required reading.) You don't need to bother with [block~] at all
here.
Ciao
