Write to a buffer for a DelTapRd UGen.
DelTapRd.ar and a DelTapWr.ar in tandem, keep in mind that they read and write in blocks equal to the server's block size. If the delay time is greater than the buffer size minus a block, the write and read heads might interfere in unintended ways. Use a slightly larger buffer if this happens.| buffer |
