+#X text 147 14 hv.conv performs convolution (i.e. FIR filtering) between
+an input signal and an impulse reponse (IR) in a table or array. The
+IR table may be updated at any time with the second inlet (or simply
+update the table contents). The hv.conv object also takes a length
+parameter which must be less than or equal to the length of the table.
+It determines the length of the convolution.;
+#X text 147 117 NOTE! Pd-Vanilla does not have a default convolution
+object. This functionality is generally provided by any number of externals
+\, such as conv~ or fir~. In order to effectively use hv.conv in Pd
+\, edit the __conv~f subgraph in the hv.conv abstraction to contain
+your own local implementation.;
