How to create a wavetable from "uncommon" samples?

[Parduz]

I need to create wavetables from an old synth PCM rom samples.
(the synth being an Ensoniq SQ1, which has "transwaves" that are a sort of wavetable)
I'm able to save each single cycle wav of the 100 waves at whatever pitch i want
BUT
they will always have a different sample count (the variation is + or - 1, whatever pitch i play to save them) and ALWAYS sampled at 29.761Hz (that's is fixed with no way to change it).

How can i convert them in a wavetable usable by synths like Falcon or Omnisphere or Synthmaster2?
From what i understand, they should always have the same sample count; trying with ffmpeg to convert them at 44100 don't give me the option to "impose" a fixed number of samples....

What should i do?

In Waveosaur, you have resample function where you can put arbitrary sample rate, you can calculate rate which will give you correct sample length (presumably 2048), or use trial and error to approximate the number.

So, you're telling me that's not the samplerate that's important, but just the sample lenght?

Yes, sample length, as measured in samples, not time. Samplerate in Hz is virtual parameter, you can change it to anything you like which will impact sample play time.
