Wavetable waveform view

@DanH I tried, didn’t work but yea the wavetable synth works pretty well to me.. I created around 1500 waveforms and added them all to my project, no problem.

Great! Any clues on how you did this? A quick walk thru on how to create the waveforms and add them to the wavetable synth would be great.

Would also be interested in how you did it : I never managed to use the WT synth

@Lindon Create a sample map with your wavetable files and map them like you want (without RR groups so only note number / velocity 2D mapping), then run the wavetable converter dialog to create .hwt files from the sample maps - the velocity will become the modulatable "table index" dimension.

If you already have wavetable audio files, then the conversion should be pretty straight forward, otherwise it will use a super experimental and hacky FFT resynthesis algorithm that tries to extract a wavetable from consecutive parts of the file.

An example project with a some "convertable" sample maps can be found here:

@Christoph-Hart Thanks Christoph, I genuinely thought it was broken

Into the rabbit hole I goooooooooooo........

Well I didn't use it for a long time so I wouldn't be surprised if something is broken in the meantime, but let me know if you run into some issues, as they should be rather easy to fix.

OK so I:

• re-downloaded the entire hise-tutorial-master
• opened the Wavetable Synth project
• made sure the guitar sample map was loaded
• pressed "convert Samplemap to Wavetable bank"

-- crashes HISE instantly.

@Lindon Try again! Worked second time for me

tried about 5 times,,, crashes every time.

[Christoph Hart]

Hmm, works here too. Don't load a sampler or anything into HISE, just open the converter dialog, does it crash then too?

Also you might want to run it in a debugger, this will directly point you to the issue.

[BWSounds]

@Christoph-Hart

Did you use the wavetable converter dialog to create the .hwt files?

Yep, took a while but def. worth it.

Making the waveform sticky is not so easy unfortunately as it's supposed to display the waveform that is currently being played.

ok, thank you, I have an idea I can try.

Great! Any clues on how you did this? A quick walk thru on how to create the waveforms and add them to the wavetable synth would be great.

I used my mother moog & a few other synths I could get my hands on, wave edit, dune3 and a few other sources.

the tricky part for me was saving the waveforms to the "ideal" length... don't know the exact time but about 1/64 of a second.
(1 cycle of the waveform) (no need to worry about that in wave edit)

I added between 4-9 waveforms per samplemap,
and from there HISE does a great job converting the samplemap to wavetable.

it create a right and left hwt file, the left one is the one I use.

Clearly I'm doing something wrong - what converter dialog?

I opened the Wavetable Synth project - its got a sampler in it already... and a wavetable...

I tried running:

Tools>Convert samplemap to Wavetable Bank

• HISE crashes immediately...

I reloaded it, and deleted the sampler

Tools>Convert samplemap to Wavetable Bank

• HISE crashes immediately...

I loaded HISE and DIDNT load the project...(so empty HISE)

Tools>Convert samplemap to Wavetable Bank

• HISE crashes immediately...

[Christoph Hart]

Yes, but can you debug HISE, since it is a super trivial crash but it doesn't do it here, so I need to know where to look.

[UD AUDIO]

Same crash here. I also tried to convert the sample map in the tutorial project without success.

Hi Christoph
here a re My Findings about Wavetables

first the Hise Stand Alone builds were done on a
Mac Pro 3.1 with Mojave 10.14.6 with Xcode 10
and Mac Pro 5.1 with Big Sur 11.2.3 with Xcode 12.5

When we Use Either the Develop or new-layout Branch
we can Export the Wave tables
after we export the wave tables we have to close Hise and re-open
to be able to play the wavetables

with Develop and new-layout we do not have the Wavetable Preview

When we use the Master Branch to Export wavetables the Hise App Crashes

if i open the project containing the wavetables created with
Develop or new-layout in Hise Master Branch
i am able to get the Wavetable Preview

i Found another Difference in Develop & New-layout Branch the LFO Wave has Steps option

but in Master Branch the LFO Wave has no Steps option!

Hope This Helps to Fix Everything!

@BWSounds @LinuxVst Hi folks, I'm testing some things with wavetable synths. Everything's working fine but when I build my plugin (or the standalone version), it doesn't produce any sound.

The standalone build asked for the sample file, so I gave it to it but it still doesn't output any sound.

Did you manage to get it to work ?

[Matt_SF]

@Matt_SF Nevermind, it's just that the wavetable file wasn't been properly installed to the {APP_DATA} folder. Do it manually and everything will work fine.

[DanH]

@Matt_SF Are there any fun modulations you can do to the wavetables? Like position or warping etc?

[Matt_SF]

@DanH you can 'only' modulate the position of the wavetable - but you can apply all existing modulators (env, lfo, etc...)

[DanH]

@Matt_SF that’s the table index correct? I did stick a lfo on it but couldn’t hear any change to the sound…
