Hi,
I'm not quite sure how xgroove~ handles 4-point interpolation compared to tabread4~ in regard to table length. tabread4~ requires indices from 1 to size-2, so if I want to tabread4~ some table from m to n then the whole table must be at least "1 + |n-m| + 2" elements big, IIR.
Is the same required for xgroove~i in 4-point mode? Or can I skip for example the first sample or the last two? And if the table is then just as big as the range set in xgroove~ (say by using the "all" message): How will xgroove~ interpolate at the ends? By just wrapping around to the other end?
Some kind of wrapping interpolation actually is what I'm after, as I'm in need of an interpolation dynamic wavetable oscillator and xgroove~ handles dynamically changing wave-table contents much better than tabread4~. If someone has suggestions for alternative approaches to dynamic wavetable oscs, I would welcome them, too.
Ciao
