Wavetable synthesis

You tried it with start and crossfader?
Sine around start = 0 seems clickier but I think it’s normal. I plocked AMP ATK / REL.

Sequenced with midi loopback.

No I just listened to your short demo! I never saw the reply to my post about using 128 and 1 (in 2015!!!). Pretty chuffed to discover works :slight_smile:

Normal it’s smooth, it’s the wavetable! :wink:

Back to wavetables then?

Yeah, I’ll probably have a play this week. I made some MATLAB scripts for extracting wavetables from audio, I’ll see if I can find them.

Thanks for this! Can’t wait to try it out and see how it compares to the dream :sweat_smile:

Can you please tell me how to get Audio Term to make 128 slice wavetables (the default seems to be 33 slices I think?)

I followed @elektrosamplist Micromonsta’s wavetable tutorial, but I can’t explain now. I’d need to do it again…AUDIO TERM is from another age…:exploding_head:

(@Hades_of_Spades) Good news, it is possible to modulate with lfos, assigning crossfader to start, midi loopback and a midi track with an lfo assigned to crossfader’s CC48 control change. :content:

Otherwise it’s clicky indeed, except with Hold, but it is limited of course.

Wavetable test (128 start points) with the folowing wavetables I made. Feel free to download and use them.
Crossfader modulation, then lfo on crossfader…

Could you use the LFO designer to restrict start point to integers? Or does it still interpolate between points?

No problem to use lfos with HOLD mode so I think yes, no problem with lfo designer.

Edit : yes, it works with HOLD.

This topic keeps popping up and I keep being interested but here’s what I don’t get:

How do I find (or make) a wavetable that is exactly 128 cycles? How does one accomplish such a thing?

I followed @elektrosamplist Micromonsta’s wavetable tutorial, but I can’t explain now. I’d need to do it again…

Here is a good tutorial i found, i also use audioterm with blofeld, big fun!

Thanks for the link @arrowtronic, finally could download the program and start learning it.

Those single waves are just great :+1:

I don’t own an Octatrack, just a Digitakt, and granted, I haven’t tried this yet, but had planned to. (at least in part) Instead of slicing up a table discretely (like classic wavetable synths) why not just create a single sample with the progression (already interpolated or not, (so perform linear cross-fading beforehand if needed)) Then just modulate the position, start, and loop points on the single wave instead of discrete cycles. It’s hacky, but would give smoother results I think. Does the OT allow you to lock a full pair of loop points in? (like I said it’s the only Elektron box I haven’t owned) This would allow you to jump and stay at a certain timbre, in cases where you don’t want to progress through the fake table.

Just a thought anyway…

I forgot to precise you can download and try theses wavetables! Not the best, but they work. :wink:

I love you

Only one loop point per slice, looping with the end of the slice. Anyway, with slice mode, you have to retrigger the sample to change slice.

With start points mode, you can loop each one of the 128 divisions of the sample, reducing length to 1 (1/128 of total length).

If you assign value 0 of start point with scene A, and value 127 with scene B, it is smooth (with a 128 equal slices wavetable).
It doesn’t seem to work properly with lfos, but you can control the crossfader with a midi lfo and midi loopback.

This video is good too for creating waves etc. Different approach (for Falcon synth) creating but the end result has to be saved as 128 for OT.
