Wavetable Synth Tutorial (how I do it)
-
@Lindon I was using 64 cycles per note and sampled the entire clarinet range chromatically so that is not completely out of touch.
Going beyond 64 tables makes no sense if you‘r intend to modulate the index with MIDI messages in my experience.

Err, 64 is pretty low for wavetable synthesis. Actually most of the wavetable synths (Serum, Ana, Arturia Pigments...etc.) uses up to 256 frames.
Also apart form that, we can't get a wavetable look like the below with Hise. I think wavetable synthesis should be improved.
-
@harris-rosendahl @Christoph-Hart @Lindon yes a point I was going to make was that when I export wavetables I've created within Serum it spits out well over 100 frames, and often 256, even if my wavetable within Serum only consists of a few frames - I guess it's running a process to create a longer table from what I've given it.
Does Serum modulate without MIDI messages?
64 frames should be enough to get some interesting modulations though.

well perhaps I dont understand how the wavetable works- but I think we are conflating two things - a"keyframe" (to use an animation term) and an interpolated frame.

@Lindon yeah perhaps Serum uses the frames you put into as 'keyframes' and creates the frames in between.

@Lindon they sound lovely though

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

@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...

@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?
-
@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.
