I didnt looked into your patch yet but usually these waveforms are stored in one table as one sample. Your tabread object should run through one waveform at a time, I have to look up how much bytes they are but assume 256, so it runs from 0 to 255 and to switch to another waveform you add n*256 where n is the waveformnumber. When you switch with a line object over several waveforms, you get the wonderful crude ppg sound but you should make sure that it goes only whole numbers without fractions so it really jumps a whole waveform each step. It can be done by sending the moving number through an int object.
Here's a patch that does exactly this. 256 waveforms each 256 samples long.
When writing it I found a bug in wrap~ in pd-0.40-2 from Miller's site:
sig~ 1 wrap~ print~ -> 0
sig~ 0 wrap~ print~ -> 1
