the usage of [nop~] in the [limiter~]-help patch was something i should never have done in the first place. it is only there to achieve a "very short" delay. you can do that as well with [z~ 64] (ok, it is one more character to type) in the limiter~help for zexy-2.0 there is no more [nop~].
hm ... nop~ was easier to implement with simd instructions ...
i hope, that miller will take some of the simd api (e.g. runtime dispatching) to make it possible to write portable simd externals for linear dsp applications ...
cheers ... tim
