Wavetable Synth Tutorial (how I do it)

@Lindon they sound lovely though

[Lindon]

@DanH -but my understanding is this is also how the wavetable works in HISE...or thats how it seems to work for me.

[Christoph Hart]

@Lindon the wavetable synthesizer is of course interpolating between different wavetables, so I was talking about 64 "keyframes" - the reason I was using 64 instead of 127 was that then I have one interpolated frame between each of the 64 frames which makes the transitions way more smooth.

yeah-nice, however with careful selection of wavetable "keyframes" I've found its possible to get useful and usable wavetables out of just 4 of them. Just in case anyone is having problems with the size of the hwt files...

[Christoph Hart]

@Lindon My use case was rather specific (the reproduction of the harmonic spectrum of a clarinet across all dynamics), so yeah 64 is way too much if you just want to make wobbel-dubstep.

why would anyone want to do anything else!

If I wanted to sample a single cycle waveform from an Analog oscillator , would this be the way to do it ?
Will it work across the keyboard or is there aliasing? Or anyone other kind of processing needed for this to work as a simple oscillator ?

@lalalandsynth You can't modulate sample start with Wavetable. So if you want to use unison + detune (like in a regular synth) to make some typical synth lead it will sound kinda weird, with some flanger effect.

when i convert samplemap to hwt, i cant get the hwt to show in the dropdown menu of the wavetable synth module. what am i missing?

[Lindon]

@Adam_G did you put the hwt in the audio files folder?

@lalalandsynth In theory, my main HISE project is a synthesizer based on cycle waveforms. But I happened to not like the results the wavetable conversion process in HISE yielded.

My workaround is to use the waveforms as looped PCM wave files from within the basic sampler. This comes with the disadvantage of having to preprocess the files: If the PCM stream is too short for the engine to loop, it will crash the application. So my rule of thumb is to have each 'waveform' containing at least 2000 samples (talking a samplerate of 44.1 kHz). This should avoid a crash even if you pitch bend the sound up by 1 octave (haven't thought about other scenarios to be proofed against yet).

@Lindon yes i got them to show by using them in a different project. thank you for the help

Is interpolation still working on Hise? I can't make it work using the "Resample" mode (to convert the samplemap to wavetable). I mean, the wavetable works, but but nothing changes when moving the index.

[bendurso]

@bendurso I just downloaded Hise 3.0.1 and the process of exporting samplemaps (with multiple velocities) to wavetables was working properly. Maybe something broke since 3.5.0.

I would use the hwt files exported from the old version but they don't work fine on the latest Hise :(
