Yeah, you're going to need to need to go with the small blocksize to realise this in vanilla Pd. But a blocksize of one isn't absolutely necessary, you'll probably get away with 8 or 16 for the frequency ranges of typical plucked/hammered strings.
Very true... blocksize 2 will give me a range of 22KHz, 4 will give me 11KHz, which might well be more than enough for the ranges of stringed instruments- time to research!! Thanks I hadn't thought of that -K
Also, the patch is extremely simple, so I wouldn't worry about the expense too much. Just wrap it in an abstraction/subpatch so that the rest of your patch can run with a standard 64 block.
Ok, here's an improvement http://www-users.york.ac.uk/~kt503/PD/kt_PluckedString_23Jan.zip
Take care not to get caught out by the creation order gotchya for [s~]-[r~] pairs :) Check the archives on this. As Frank pointed out recently on a similar topic the minimum delay loop time with this is actually zero, so an extra [z] wouldn't hurt.
