Yes, the trigger to 6N is the way you can tie JF’s rhythms to external clocks. I’m using it from time to time. Just wandered if there’s a possibility to use JF’s internal clock to get the straight rhythm. And as it turns out there isn’t.

Thanks for your suggestions, everybody.

by straight do you mean no phasing?

Why can’t you just self-patch IDENTITY’s output to 6N to reset them all? This can get you interesting rhythms when INTONE is not fully CW.

With Intone at noon, CCW or CW, the ratios are all divisors or multiples or identity so there should be no phasing.

I would do what @voidstar suggests and leave Intone at full CW or CCW. Easiest way to synchronize the channels is switch to sustain mode, let all the channels stop, then back to cycle. They should stay sync’d and in-phase for a long time.

If you want multiple copies of a single division/multiple, use a mult module or stackcables.

I just got a second hand JF and I was curious and trying to figure out if something I’m running in to is either user error, because of firmware updates, or a faulty, ill calibrated module:

does the JF.RUN command in the Just Type function work the same as it did when demo #6 of the Just Type studies was released?

The M script is running these slight changes to the JF.RUN Param;

X RAND 6; Y RRAND 3 6
Z DRUNK
EVERY 5: JF.VTR X V Y
IF EQ Z -1: JF.RUN VV -250
IF EQ Z 0: JF.RUN VV 0
IF EQ Z 1: JF.RUN V 1

I’m seeing that if I keep the module in synth mode, the JF.RUN command only works when I turn the INTONE/FM knob away from 12 o’clock. It appears in the demo as the knob is directly 12, yet I get no effect… anybody able to test this or give their thoughts?

#564

In synthesis mode, the gray FM knob controls FM index (ie amount of modulation applied to each oscillator by its internal modulator). At noon, no modulation is applied. Turning it away from noon increases modulation. The RUN voltage controls FM ratio (ie frequency ratio between the internal modulator and the carrier oscillator).

So, when the gray FM knob is at noon, the RUN voltage will seem to have no effect because the modulation index is 0.

#565

This is a Just Type specific question, but is there a good way to understand the behavior seen when sending negative velocity values?

#566

Interesting. In the demo I saw, it didn’t appear as if the knob was away from 12 o’clock. It also seems interesting that the FM knob would attenuate the incoming RUN voltage (which in the case of the JT situation, is just a virtual application of that Voltage). But hey, if that’s how it works, I must’ve seen things wrong in the demo.

#567

It is not attenuating the run voltage. In synthesis mode, the run voltage is setting the frequency of 6 different internal modulating oscillators as ratios of their matched carrier oscillator - one for each channel of Just Friends.

These 6 modulating oscillators each pass through an internal VCA. That VCA’s output frequency modulates each of the JF channel’s main carrier oscillator. The 6 internal VCA’s are opened and closed by the FM knob and FM CV jack which acts as an offset for the knob. The FM CV/knob are thus controlling the depth of FM by the 6 internal modulating oscillators. This is known as controlling the FM Index or amount of FM.

Thanks for the explanation and I apologize for the incorrect terminology.

But what I don’t understand is how the RUN voltage is somehow dictated by the FM knob and the FM Index. Is the run voltage (and the associated shifts that it provides based upon switch position) somehow related to the FM? That’s why I’m a bit confused.

Okay, I’ve found the explanation in the Whimsical Raps description of it all. Thanks for that info!

Hello, here’s my last patch with two JF :slight_smile:

There’s a long version and a short one because I don’t know which one to choose !

Is there a way to use one of the knobs as an attenuator for all 6 lfos?

#571

This isn’t possible with just friends on its own. If you’re using teletype to send just type commands, the amplitude of an output can set with a command. Otherwise you need external attenuation.

Just to help me commit to my depth year goals, something like the 4ms Ensemble Oscillator is surely possible with Just Friends + Teletype?

The Ensemble Oscillator is a unified polyphonic voice of sixteen complex oscillators combining additive, FM, phase-distortion and wavefolding synthesis techniques in new unorthodox ways. By quantizing the oscillators to scales or series of harmonics, the Ensemble Oscillator allows you to explore the sonic boundary between musical chords and rich evolving textures.

Specifically interested in the poly chord quantizing/spreading. Without getting into specifics there is a way of doing this with Just Type?

#573

Absolutely - in standard JF mode, you can set the frequency of each channel as a justly intoned ratio proportional to the IDENTITY frequency, allowing you to create arbitrary chord structures. It’s just a matter of defining the ratios, which is a little bit hairy but also fun. This has the added advantage of being able to still interact with the INTONE control to spread the oscillators. In synthesis mode (JF.MODE 1), you can set voices to specific MIDI notes (e.g. C3, E3, G3) via the JF.VOX commands, so it is a bit easier to set up arbitrary chord structures.

Could you please say more about how to set the frequency to just intonation ratios?

Thanks!

#575

I will refer you to the Just Type docs (cf. JF.TUNE)!

Oooooh I was thinking about making a harmonic oscillator for norns as a next project but perhaps norns/crow/jf in a more fun option

Ah, I missed that this was a Just Type thing… No Teletype here (yet)…

Something to look forward to!
Thanks!

#578

Crow can do it too…
