Hi Peter:
First of all thank you for porting this oscillators to Prologue, they are great!
I found that there is somenthing wrong with the Row and Column selection and how the waves are selected in the Wavetable Oscillators (mo2_wta to mo2_wtf).
In the documentation you say there are 6 oscillators with 4 rows each, and I asume that there are 8 columns in each row. And you say that Shape selects the Row and Shift+Shap selects the Column.
But I can count 8 divisions (setting Interpolation to 2) when I turn Shape knob, so I think Shape meant to control Column instead of Row.
And I can count 5 divisions when I turn Shift+Shape knob. I think that should be the Row selection but I don't know why there are 5 Rows instead of 4...
The inverted nomenclature is not big problem, but according to the Braids manual within a row, the waves are sorted by spectral brightness, so there is some correlation in the order of the waves within a row and I expect that scaning the waves within a row using Shape the output will be correlated waves wich increases in harmonic content. Instead of that there are 3 or 4 waves correlated and the rest are mixed from other rows, and if I change rows I can found the waves that supposedly belong to other rows.
I don't have a Plaits module to check all this, but I tried it in the VCV Rack version (which is free) and confirmed that the wave order within a row is different in the mo2_wtx .
I think that you planed to assign Shape to Row and Shift-Shape to Column as stated in your documentation but at some point changed the amount of waves per turn of the knobs (because is more logical to have more divisions/waves in Shape knob) but didn't changed the assignment of the knob...
Hope you understand what I mean...

Hi Peter! Welcome back!

Thanks for fixing up R&C on wta-f. Please change this line:
parameters.harmonics = p_values[k_user_osc_param_id1] == 0 ? 1.f : 0.f;
To this
parameters.harmonics = p_values[k_user_osc_param_id1] == 0 ? 0.f : 1.f;

That will reverse the sense of Interpolate back the way it was, and still keep wavetables straightened out.

Hi Peter,
First: Thanks for implementing mutable osc in Prologue. Amazing job!
I have problem with the modal oscillator: no sound at all.
I tried to send it (alone) from librarian several times to Prologue. It appears in it. I enter parameters as you describe in your readme tips (no "0" values)... And I still have no sound.
Is it a known issue, or maybe I missed something?
Thanks again for all your works,
Regards,
Mathieu.

Hi! I really like the sound of the Modal Strike osc on my NTS-1, but every first note in a new key sounds as if some part of the program is still running the previous key, resulting in a kind of portamento effect, or maybe more like two notes at once. It is most pronounced when going between octaves.

Tried loading all the oscillators onto my 3-week old minilogue xd – that had basically no problems prior – and immediately every fourth note i played in poly mode didn't make a sound. I don't know if i just got a bad unit, but it was working fine until i loaded the oscillators.

Will this support also the upcoming KORG NUTEKT NTS-1? Would be great if it would.

Thanks for sharing this project.
