Attached are two example approaches to this problem. Both involve a
phasor signal that is split into two phasors which are out of phase by
half a period using [-~ 0.5] and [wrap~]. You can use these two phasors
to alternately play two tables with tabread~, if your source signals
are in tables, see combine-tables.pd

If your source signals are not in tables, combine-signals.pd shows a
crude switching between two signals using square waves out of phase with
each other. You make these square waves from a phasor wrapped out of
phase with itself just like above. (Of course you can also just use one
square wave which you multiply by -1 and shift up by [+~ 1] after creation.)
