Just Friends v4.1

[Justmat]

i’m seeing this here as well.

(i feel like all this 4.5 talk should probably be moved to a 4.5 focused thread, as these issues aren’t a part of 4.1.)

Another question, part of my current exploration of my new JF :
While using TT+JF in MODE 1, is there a way to apply a CV to the pitch ? What am I missing ?
EDIT : CV into the RUN input.

Well, as simple as it seems, I didn’t figure it out. Is it possible to control JF’s pitch via CV when used in ‘synthesis’ mode with teletype ?

Assuming you don’t have a Telexi, have you tried using IN ? It will accept positive voltages which you could bring in to transpose or quantise stuff. Obviously you’re limited to a single variable, but you can math it for multiple ideas.

e.g
A sequencer into IN

N.B ? TOSS 2 7 2193 scale mask. True = D Maj 7, False GMaj 7 (R100010010001)
A IN; B / IN 2 A is IN, B is half of IN
J + 1 WRP J 0 7 counter from 1 - 8
JF.VOX 1 N.B J V 5 ascending arp over 2 octaves
EV 3: JF.VOX 2 QT.B A V 5 quantise and play A / IN to the Gmaj 7
PROB 10: JF.VOX 3 QT.B B V 5 quantise and play B to the Gmaj 7

you can also use VN to scale IN into N friendly numbers.
Bonus ball you can patch a JF output into IN for self playing shenanigans! CYCLE helps.

You can run M at 10ms, poll a CV input and use JF.SHIFT.

[desolationjones]

n.b. the settling time of TT IN jack can be pretty long. For applications like this, I’d recommend quantizing in script like @Obakegaku demonstrates.

[chapelierfou]

Thank you all. Unfortunately, none of the suggestion will work (smoothly).
What I have in mind is simply vibrato (external LFO modulating pitch).

[sixolet]

Try the fm input perhaps?

[chapelierfou]

in synthesis mode, I think it’s just adding offset to the internal CV (?)

[Obakegaku]

From the Just Type Github

Internally each voice contains a linked sinewave oscillator providing frequency modulation over the function generator. FM index (ie. amount), is controlled with the FM knob & CV input. The knob functions as normal with INTONE-style modulation CCW, and uniform modulation CW. FM CV input is a traditional CV-offset where positive voltage increases, and negative decreases modulation. The frequency relationship between the modulation & carrier oscillators is set via the RUN jack, though is matched at 1:1 with no cable attached. Positive voltages move toward 2:1 at 5V, while negative sweeps down to 1:2 at -5V giving many grumbles.
…
Try turning the FM knob counter-clockwise and sequencing a fixed cycle of tones-- The timbre of the voices will cycle through 6 levels of FM depth. This can be great with 6 tones where the note order chooses timbre, but even more interesting if your sequence is 5 or 7 steps long, creating long phasing patterns for movement in a simple arpeggio.

You can also create your own crude i2c land vibrato if you eat up some variables.
I quit like it, but it might not be what you’re after. @desolationjones taught me this pendulum technique like a year ago??? and I still find cheeky ways to use it.

IF EQ A 1: B 1 hax pt1
IF EQ A 5: B -1 hax pt 2
A + A B Boiing. A pendulum counter 1,2,3,4,5,4,3,2,1
N.B 4 -3; J N.B RRND 1 10 E Melodic Minor scale melody
JF.VOX 1 + J * A 25 *Plays melody Wobbliscuously

[chapelierfou]

Well, as I read this in the document, I would expect that feeding a triangle LFO with a small amplitude to the RUN input, with the FM knob turned CW would produce vibrato. It’s not really. Maybe my ears trick me but it sounds like it modulates both frequency and index at the same time.

[desolationjones]

You are hearing correctly. The FM knob (CW from noon) its CV input change the index of the modulation of each voice by a sine wave. The frequency ratio of that sine wave relative to the voice is controlled by RUN voltage. Unfortunately, at -5V into RUN the minimum ratio is 1:2. So there’s really no front panel way to adjust pitch.

[chapelierfou]

Glad to know I’m not crazy.
I find it quite sad as TT doesn’t shine in smooth curves. I’m really missing a way to apply ‘traditional’ fm.

[mlogger]

For vibrato I use w/del - adjusting mod rate / mod amount from teletype i2c

Also another way - attenuated / slewed LFO into JF FM input.

And for smooth curves from TT I use different slew times on random voltage ranges for each of the physical CV outputs.

I can’t find a JF v4.5 thread, so putting this here: Release Version 4.5.2 · whimsicalraps/Just-Friends · GitHub

More small fixes for v4.5

• Wavefolds are applied exponentially smoother onset of folds, then more drastic folds towards CW.
• Noise introduced by the wavefolder is reduced for V3 hardware (V2 may be better, but needs testing)
• CURVE knob is interpolated at audiorate now to reduce noise when manually adjusting the wavefolder

[crucFX]

oh my, V3 Hardware

[chapelierfou]

@xenus_dad

Yeah ! Can’t wait to try this !

[Sascha]

What is the different between v2- v3 … How can i See what Version i have ?

[crucFX]

V3 is not out yet - V1 has Silver Clouds, V2 has Gold Clouds
V1 - Silver Clouds

(lol not my pic)
V2 - Gold Clouds

[Sascha]

I now .i Hope the v3 has Not to much different to V2 . When… i need a third jf

[boomblip]

Probably not if its running the same firmware, imagine he is changing some parts due to shortages and such.
