anyone know of a vst like the sps subsonic effect?

that way with older tracked out beats i could use it on the kicks without having to run it through the sampler and re-record it again.
thanks

i found this free drum replacement vst that could be used in workaround way called replacer:

if i loaded a bass tone into it i could change the pitch with the vst, then adjust the dry/wet settings.

MDA SubSynth is free. It can put a subsine based on frequency (i.e. turning anything into a sub at correct pitch) or it can work like Subsynth on the 404 and just play a sine at the frequency you tell it at the volume threshold you set.

It comes in a pack of 20+ other effects.
