Object: tiar/tuning/DetHz

see the help patch: menu: Help -> Library -> Community -> tiar -> tuning ->DetHz

An old trick to get the fat synth sound consists in slightly detuning oscillators.
With the axoloti, it is often achieved by ctl-shift mouse drag over the pitch knob of the oscillator (or by selecting the knob and typing in accurate values thanks to @lis0r ). This is pitch detuning.

A slight detuning generates that slow, smooth and delightful chorusing / doubling effect.

The problem with pitch detuning is that the chorusing rate increases in the higher range. It is often too fast and more fuzzy than smooth.

DetHz allows to have a constant chorusing rate all over the keyboard. It adds a frequency offset - as opposed to a pitch offset - to the control signal:

Both oscillators are tuned exactly the same way, but DetHz modifies the pitch control of DP2Saw_2. DP2Saw_2 is "frequency detune" relative to DP2Saw_1.
Try the help patch: Help -> Library -> Community -> tiar -> tuning ->DetHz and play notes from the lower end of the keyboard to the higher end.

Here are the approximate detuning cycle/rates you will get with the control parameter:

  • 1: 8s cycle
  • 2: 4s cycle
  • 8: 1Hz
  • 64: 8Hz

[EDIT 27 feb 2018] Added an inlet to modulate the offset ie control the beat/chorusing speed.

Object: tiar/osc/wf_16_harm

try menu: Help -> Library -> Community -> tiar -> osc -> wf_16_harm
is a companion object for the 16 segment anti aliased oscillator tiar/osc/16StepsDP2.

It allows to control 8 harmonics and the interpolation type, linear, steppy or even reversed.
This interpolation type allows to recreate harmonic imaging typical of old semi digital synths.

patch: ToTheStars

menu: File -> Library -> Community -> tiar -> synths -> ToTheStars

This 8 voice patch uses a pair of new 6coseg m oscillators per voice and a feedback delay.
Phasing and filter effects are produced by modulations of the 6coseg m waveform parameters.

#47

Object tiar/lfo/555LFO

try menu: Help -> Library -> Community -> tiar -> lfo -> 555LFO
This LFO mimics the LFO waveforms of astable oscillators used in some analog effects (such as phasers and flangers).

pos and neg add some asymmetry.

#48

Object tiar/osc/SelfPMSync

try Help -> Library -> Community -> tiar -> osc -> SelfPMSync

This is a band limited sawtooth generator with embedded master oscillator. It allows to produce some classic analog sync sounds (try the help file).

  • beta is the feedback coefficient, it controls the brightness of the waveform.
  • octaviate controls a second slave oscillator. Positive values octaviates up one octave, negative values produce a "squarish" type of sound.
#49

Object tiar/artic/sentence1

try menu: Help -> Library -> Community -> tiar -> artic -> sentence1 (play legato notes and chords and see how vowels are chained).

sentence1 is sort of a note counter.
It counts how many notes you have played, its output can be used to chain parameter changes (such as formants in the example).

  • notes played in a 0.1s interval will be considered as one (useful for chaining on stabbed chords).
  • the counter resets after 0.2s when all notes are off.


Note: This example help patch uses sentence1 to control a @lokki s formantsettings object that controls a bunch of SyncPM2.

#50

haha, nice! thanks for sharing.

#51

Now.. we can try to add different transitions between vowels...

but, i think that it is somewhat tricky !!

#52

well you can fade between s1 and s2 in my formantsettings objects. (via the c inlet, but you have to set them to different vowels to hear actually a difference) otherwise s2 is actually pretty much useless :slight_smile:

but i imagine you want a different transition...

#53

Yes, da di de do du !
I will experiment withh short stops, formant deviations and noise bursts, will be fun !

#54

more like:

ai ae ao au
ia ie io iu
ea ei eo eu
oa oi oe ou
ua ui ue uo

but stops deviations and bursts sound great to me!

#55

Object tiar/osc/DevilSync

try menu: Help -> Library -> Community -> tiar -> osc -> DevilSync

I call this osc "devil" because its waveform looks like horns...

It is antialiased - including the master sync - by a first order differentiation algo.

#56

In my house these types of waveforms are called Batman :slight_smile:

#57

Also known as PHB wave which stands for pointy-haired-boss waveform..

#58

It should not be confused with the KW wave... which is smoother.

#59

Ha :slight_smile: ...... 20 batmans

Hi. I can't find the ZDF SVF 2 filter in the community library. Has it been posted yet?

#61

it's there, but not in the browser. open a new patch, load the object (ZDF SVF 2) and load it's help patch.

#62

Sorry, I'm new to this. What do you mean when you say load the object and it's help patch? Where do I find it?

#63

open a new empty patch, doubleclick on the empty space in the patch and the object browser should come up. type ZDF (yes case does matter, something that maybe should be changed? @johannes) and choose the version two. you now see some sort of preview of the object. click on the black triangle in the top left side of the object and choose help. that's it.
