one way to do this is to implement your own delay line using four
[tabwrite~]s and a single [tabplay~] or [tabread4~]. you'd have to
conceptually reverse things though, because rather than tape moving around
in a loop and the heads staying still, as happens with an analog tape
delay, you'd have the 'tape' staying still while the digital read and write
'heads' (the [tabwrite~] and [tabplay~]s or [tabread4~]s) moved around it.
the only problem with this is that you can't change the record rate of a
[tabwrite~].
hmm. [tabwrite4~] anyone? it should be possible.. just invert the
interpolation equations...?
