pfm2 : 2.21

[SirPrimalform]

:O

I did not expect to see this any time soon. You are amazing!

I just need to figure out how to convert the waveforms into the right format. I've been additively generating them in Reaper and I can export in 32-bit or 64-bit FP wav at the right number of samples, it's just how to get that into the text format.
I'll have to try and write a little script to do it or something next weekend. Too late to start messing with that on sunday night!

Yeah, awesome. Gonna wrap my head now how to get txt with values from Renoise's sample editor using LUA

Bravo Xavier!
With my recent moving between houses I didn't finish to install my music making space yet, but I can't wait to get back to the PreenFM

Xavier, does usr*.txt should have specific format? I tried to make my own waveforms by converting Adventure Kid ones and didn't had any success with them. PFM2 shows broken up name with pseudographic symbol instead of first glyph, osc remains silent.
Here is an example.

Your waveforms work just fine.

Yes, i described the format in the first message of this thread as well as in the newly updated doc - "2. Operator / Shape" :
http://ixox.fr/preenfm2/manual/synth-edit-mode/

600 is not a power of 2
As the preenfm2 does not interpolate between sample i suggest to use 1024 samples if possible for better sound quality.

If a non power of 2 is found, a '#' overwrite the first caracter of your name and the sample is not loaded.

Ah, i see now. Thanks!

[clément]

Ah yes! I'm using those Adventure Kids waveforms in Ableton, looking forward to try them within the PreenFM2!

[Xavier]

I didn't know those waveforms. They seem to be all 600 samples.

Seems like we need a firmware 2.02 that would accept any number of samples in the waveform text files.

This could be cool but this can also introduce some artefacts i guess. Anyways some vocal AKWFs usage can sound interesting being modulated or vice versa.
I made some waveforms.
1 approximisation of TX81z waveform 7 - sounds pretty close
2 approximisation of TX81z waveform 5 - same here
3 generated phase distorted sine
4 approximisation of TX81z waveform 8 - has extra hifreq but sounds close too -- i guess TX's lookup tables have less detalisation

[kuzma_p]

5 symmetrically mirrored AKWF voice wf to reach 1024 samples
6 same

This man helped me:

I also used this tool to generate waveforms

FYI Renoise has fully functioning demo so you can install this tools and use only Renoise's sample editor. You should read some manuals though.

Got this while tweaking patch with 3 custom waves.

They sound amazing!

[Xavier]

Thanks for the feedback and bug report.
Will take a look.

Carrier's? pitch starts to drift when you modulate it with my custom waveforms 1, 3, 4 and tweak IM with rest waves pitch stays static.

I think it's because your waveform are not "centered" the average sample is not 0.
I'm working on a 2.02 which will do a bit more processing on the user text files. Waveform will be centered and normalized.
