      @Christoph-Hart said in Wavetable waveform view:

      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.

      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...

        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.

          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

            Hise Develop Export Wavetables.png

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

            Hise Develop no Wavetable Preview.png

            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

            Hise Master Branch.png

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

            Steps Present in Develop.png

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

            Steps not Available in Master Branch.png

            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 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.

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

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

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

                        @DanH yes it's the index. But did you convert your samplemap successfully ? You have to spread your waveforms across the velocity range of the sampler and convert the samplemap to a wavetable using HISE's converter tool (default options should be fine).

                          @Matt_SF oh right - I just spread it across the keyboard lol

                          How do you spread across the velocity range?

                            What is the advantage of using a WaveTable over a Sampler?
                            Because if you can only modulate the position then a sampler can do it if you spread your waves in the samplemap.
                            Maybe it is an efficiency difference?
                            I'm asking because I began a kind of wavetable based on a sampler and I don't know if I better have to switch to a real wavetable module, I'm not familiar with all of those...

                            Can't help pressing F5 in the forum...

                              @DanH just define the min-max values for each 'velocity' layer, define the LoKey/HiKey numbers, and run the wavetable converter.

                              @ustk the main advatage of using wavetables is that the transitions between the different waves are interpolated, hence modulating the position will be smoothed.
                              With a sampler you have 2 options if you want to do the same. Let say you want to go from sine to square :
                              Either you layer your samples like on the picture above, but when modulating the position, you'll get abrupt changes between sine-tri-saw-square (but maybe that's what you want / you don't care).
                              Or you can layer your samples so each one 'crosses' the previous and the next but this is like dry/wetting a signal, there's no "morphing" between the waveforms.
                              Try for yourself ! I personally like wavetable synths :) .
                              Christoph put an example project in his repo.

                                @Matt_SF right, how many velocity layers do I want?

                                  @DanH that's up to you 😆. It depends on your project and what you want to achieve...
                                  For an oscillator which goes simply from sine to saw, then 2 waves should be enough but for complex wavetables you should use as many samples as needed.
                                  Your samples are the 'key-frames' you want to go through. HISE converter then creates the middle frames.

                                      @ustk You can use up to 128 different wavetables for each note. If you're doing this with a sampler the voice count will rise up ridiculously.

                                        @Christoph-Hart Ok I see. In my case I need only 4 waveforms, monophonic, so I don't think it is as bad.

                                          @Christoph-Hart Oh, and I forgot to mention the user should be able to select whatever wave he needs between this group of 4 dynamically from a browser and even create his own shapes. So I think I better have to stick with a sampler...
