where do can I find some wavetables to use within WT LFO/OSC?
Any out-of-the-box libraries out there?
Also: what’s the standard for WT LFO/OSC in Rack?
IIRC Serum use 2048 samples for each Wave, while the default Basic.wav come with Rack is 1024: any info about the specifics?
Here’s a couple of links:
and some very nice Virus TI sampled wavetables on this page:
and here’s one I made
It’s a 32bit float x 128 waves x 2048 wave points of a ramp, morphing to triangle to saw, like the Moog One waveform of some fame.
(sorry about the jumpy loop, may get replaced if i find a decent gif capture software.)
There’s a python script to generate it too. GitHub - jpnielsen/wavetables
If the reader is skilled in python, I’d like to get that script optimized - I use a library to “grow” the waveform, that makes a new copy of waveform each time a cycle is added - very inefficient.
Sorry, no docs for WTLFO or WTVCO (yet)
VCV - Fundamental
VCV - Fundamental
Default is 1024 wavepoints, but it’s configurable.

Thanks for all useful informations!

Thanks for posting that saw to triangle to ramp wave table! I used it to create a really cool hybrid AD EG / VCA / Wave Shaper out of a WT LFO, which then became the centerpiece of a patch that I used in a live performance.
I have a considerable backlog of performances I’d like to clean up and post. Here is a start - Halloween Waltz from the October 31, 2022 VOM. I love the melody, and I think the patch is really cool. It features a number of VCV Fundamental Constructs using Rack 2 modules. Of particular note is a hybrid polyphonic Attack Decay Envelope Generator, Voltage Controlled Amplifier, and Wave Shaper - all constructed from a WT LFO (Wave Table Low Frequency Oscillator) using a
morphing saw to triangle to r…
