Hey everyone! I have a pretty particular question about samplers.

I am in the process of trying to create a soft sampler bass patch (specifically in Kontakt 4). I'm trying to create looped single cycle waveforms via additive synthesis for each note for about 2-3 octaves. This works great because I can get every single note just the way I want it to sound.

A problem, however, is introduced when trying to use portamento. Kontakt has a built-in portamento script that seems to merely speed or slow down the sample based on which way you slide the note (I think most samplers work this way, correct me if I'm wrong). This sounds like crap when doing a portamento shift of any more than about 3 semitones.

Now I have an idea:
Say you do a portamento shift from C1 to C2. The sampler then crossfades between the sound of the C1 sample being sped up to C2 and the C2 sample (slowed down to C1) being sped back up to C2. This could potentially sound pretty good I think.

An even more complicated way would be to do the method described above but for every single note in between the two notes which you are doing the portamento slide. In theory (mine at least, which could be really stupid) this should be a smooth sounding transition if done right.

Are there any samplers or Kontakt scripts that do anything similar to this? It's probably a long shot but I guess it's worth asking. I would script it myself in Kontakt if I knew the language, but I haven't been able to grasp it yet.

Thanks in advance for any input!
