Tale's JSFX Pack

[Tale]

I have just uploaded v20151107 of my JSFX Pack.

Changes:

• wave: Optimised Catmull-Rom spline interpolation.
• wave: Added Hermite, B-spline, 2nd-order-osculating interpolation.
• wave: Fixed Lagrange interpolation.

rats!

i heart rodents.

I updated the GUI version of the Mono/Poly synth in the stash. No visual change to the interface, but the mousewheel can now be used on the knobs without the need to hold down the left mouse button.

Note: anyone wanting to use the GUI version must also have downloaded Tale's JSFX pack for it to work as it includes all the referenced lib files.

cheers,

argee

Cool, thanks.

[argee]

OK, things have clearly gotten out of hand now - I added a keyboard just to see if I could do it.



this version is available here:
THE FILE IN THE STASH HAS BEEN REMOVED - THIS IS NOW PART OF TALE'S JSFX PACK. SEE THE LINK IN HIS SIGNATURE.

Having the note on/off functions already built in certainly made it easier.

The previous version is still available in the link in my post above this one.

I think I should stop now.

cheers,

argee

15/11/15: I've re-uploaded it now to fix a few minor bugs with the keyboard.

Cool! Meanwhile I have ported all recent (since v20150215) changes to your GUI version, so it now also has last-note priority etc.:

Would it be OK if I include the GUI version as an option in my installer?

Absolutely! I'm flattered that you want to include it.

Great, thanks.

Note that there still is an issue with the GUI keyboard in poly mode and with a long release time (e.g. 1000 ms). If I hold down the mouse button and wildly move over the GUI keyboard, then I get hanging notes and even notes appearing out of nowhere. If I do the same using REAPER's Virtual MIDI Keyboard, then I don't get this, so I guess one of us should fix this...

[argee]

Ah, I see what you mean, it's an interesting "effect"

I'll see what I can do. I want to avoid modifying any of your code if I can just to keep things simpler, besides which I only have a basic understanding of how it works!

cheers,

argee

edit: I'm wondering if this could be a limitation of JS in that the notes are being triggered from the @gfx section which I believe runs 30 times per second?

[argee]

Well, I've been trying various things without much success, so maybe better keep this one off the table for now.

For anyone wanting to use the keyboard, just bear in mind it works better in Mono mode and if you use it in Poly mode don't go crazy with the dragging!

cheers

Thanks for looking into this. Hmm yeah, that could well be. I think I will have a look.

This moves the note_on()/note_off() calls out of @gfx into @block, i.e. out of the GUI thread into the audio thread.

EDIT: Uploaded patched mono_synthGUI:
http://www.taletn.com/reaper/mono_sy...o_synthGUI.zip

[argee]

Yes! Tale, you're awesome! It works great!

It didn't even occur to me that code could reside just as happily in the @block and @sample sections.

Thanks!

argee

edit: I think I'll remove the one I posted in the stash and it can just be a part of your package.

[argee]

I did discover one more little bug with held keys performing multiple triggering of the same note. I think I managed to fix that. I also added a little circular slider to adjust the MIDI velocity of the keyboard. I've attached the updated file here.

Thanks again for this great little synth! I use it all the time.

cheers,

Cool, thanks. However, now the last played GUI keyboard note seems to hang, both in mono and poly mode.

Good to hear!

[argee]

OK, I THINK I've got it fixed now. It's weird, I wasn't experiencing the hung notes yesterday and yet today I did. It tests OK here, but I'll let you give it a shot too, maybe I've created some other issue.

It seems it was about where the "previewnote = -1" statement was placed in the @gfx section.

Here's hoping!

Almost there, but now I still get a hung note when moving the mouse cursor off of the GUI keyboard while holding a key.

The multiple triggering of the same note when holding a key was caused by @gfx temporarily resetting previewnote, and then while looping through the keys @block would see the previewnote change before @gfx could set it again.

So I have reverted your last fix, and I have come up with an alternate solution. In theory it could still go wrong, but thusfar I can't reproduce anymore.

[argee]

Ha! When I saw your post I looked at my version and realized what the culprit was.

This (at line 870) was supposed to take care of being off the keyboard:

mouse_x < 36 || mouse_x > 614 || mouse_y < 360 || mouse_Y > 444 && start == 1? (
  all_notes_off();
);

But with all the changes, the "start" variable is no longer being used, so it's never 1!

Removing that fixes the problem edit: although it's probably better to use "previewnote =-1" instead of "all_notes_off()"

Sounds like you've fixed it anyway.

Ah, right!

Yeah, because else it will cut off your MIDI notes all the time unless the mouse hovers over the GUI keyboard... And also because else it would stop all notes from playing, not just the single note that was be played on the GUI keyboard.

Anyway, all seems well now with your fixes applied.

IMHO your fix looks cleaner, so lets go with that. And the GUI part of the code is yours anyway, so...

[Tale]

• Added window function viewer example.
• Added low-pass windowed FIR/FFT filter examples.

[Tale]

*BUMP* I have updated my JSFX Pack to v20160802.

Minor changes:

• array: Added get last row pointer.
• lfo/poly: Optimized x^2 as sqr(x).
• zdf: Fixed/simplified peaking EQ/low/high-shelf.
• Added mono/poly synth array example.
• Americanized documentation.

Hi Tale.
Did you hear about ReaPack extension? As JS author you can easily share/update you amazing stuff this way.

Yeah, I know, but I'm too lazy, for now anyway...

[mpl]

I can add it by myself and invite you to ReaTeam. Will it be OK for you?

[Tale]

Thanks for the offer, but for now I think I would rather stick with distributing it only through my own website.

Of course my pack is GPL, so you could always fork it if you really want, but then you would have to keep it up-to-date yourself...

[Tale]

I have (finally) uploaded an update (v20171015) of my JSFX pack. There are too many changes to list them all here, so here are the highlights:

• drum_synth: Added GUI (resizable, Retina aware).
• drum_synth: Added bass drum 2, shaker, sticks.
• colored_noise: Added notch filter.
• Changed license of plug-ins to LGPL.
• Changed license of libraries/examples to WTFPL.
• cplx: Added complex.jsfx-inc complex math library.
• uint: Added uint.jsfx-inc 32/64-bit unsigned integer operations library.
• four: Added fft_real_synth.jsfx-inc real FFT version of Fourier synthesis library.
• midiq: Added simple ("queueless") interface.
• Improved/updated examples, documentation.
• Many (minor) optimizations.
  Full changelog...

[vanhaze]

Amazing work Tale, thanks so much for this !
"Dank U wel" !

[IXix]

Lent ska hat!

[Tale]

Hehe... Alstublieft!

BTW, I forgot to mention that the new drum_synth GUI is fully resizable, and supports Retina.

I would love to see this in ReaPack. It's truly worth the hassle of setting up.

Loving the drum synth.

[Tale]

It seems I forgot to post the update from earlier this year, oops! Anyway, here's another update, adding midi_vibrato, a MIDI vibrato via Pitch Bend plug-in, and lots of minor changes.

[IXix]

Thanks Tale!

[Tale]

BUMP for v20200730, adding a waveform generator/viewer to the examples, plus some minor changes.
