Hi,
2 questions for old g0 users:
- In live mode, it’s difficult to understand where the sample restarts and for how much time but despite this I can achieve great results. But how do you use the depth setting?
- in Sampler mode, how can I latch the V/Oct, because if I hold and push the function button it reload my sample?
thanks

Depth is equivalent to the start position of the grain. It works the same in both live and sample mode, but unless the buffer is held it will update continuously. If the width (grain size) value is large enough to contain the entire buffer or sample, the depth parameter will do nothing; it has a noticeable effect only when the grain has enough space to move up or down.
how can I latch the V/Oct, because if I hold and push the function button it reload my sample?
I’m not sure I understand. In sample mode, zoom and the function button are used to add interpolation on the next loaded sample. The 1V/oct input is always 1V/oct. The FM input has a variable-value V/oct. Sorry if that was no help.
Thanks for the reply, it helps.
So the depth setting makes more sense when held by a gate.
for the V/oct, I talked about the tracking output, sorry it wasn’t clear.
does the v/oct output work in card mode?
I don’t know what exactly happens but if I use it to modulate something else or in self modulation it behaves differently when I press the blue button…
but does it follow the pitch of the loaded sample?
pressing the blue button enables “listening” to the audio input, eg the pll gets newly “calibrated” i think.
In fact, the v/oct doesn’t track pitch in playback mode…
Other g0 questions, sorry if it was already asked and thanks @kilchhofer @Net for your patience.
The only way to use it as a “synced” pitch delay is to adjust manually the width parameter?
The cool thing is that you can change the delay time without affecting the pitch…
Because of my terrible english, I think I don’t understand this sentence:
"positive going edge on the reset input and continues to play this until a negative going
Why sometimes my g0 drift strangely in unlit mode?

This means a rising voltage and, as the icon suggests, it’s probably intended to be a gate most of the time. But any voltage rising high enough will hold the buffer for as long as it is high enough. As soon as the gate drops to zero, or the whatever voltage drops down below the threshold, the module stops playing only that one grain. I believe the two live modes differ only in how they behave when a rising voltage holds the buffer.
Can you give more details? Are you modulating anything or holding the buffer, etc.?
OK, I think I got it. thanks
Drift usually happens when I turn on my system but also "sometimes " when I unplug and plug something else in the input.
If I modulate the parameters it turns back to normal acting but I lost my settings ans that’s a terrible thing with mungo modules…
Maybe because the audio input is too weak?
Actually I’ve tried to use this module with simple pitched sequences to understand it better and I realize it’s definetly more a granular tool than a classic pitch shifted delay because with short width it tends to restart the reading of the buffer in a way I can’t understand…
Nevermind, I don’t play melodies…
i have to “reset” my g0 everytime i power on my case, not sure why this is but i always
press the buttons with zoom out a few times, i do this with all my mungos, it seems to work 
g0 is a granular sample player, it definitely isn’t a delay. but you can patch it so it resembles a delay, in fact you have two ways of turning the g0 into a “delay”: with the depth offset (start point) it’s pretty easy to delay the output, but adjust the width (grain size) to as small as possible so you don’t get confusing repeats .
with the width control you can set the grain size to the delaytime you want, for this you have to have depth at zero…and all that with no pitch deviations to the input.
here some old and clumsy tests to illustrate these two “delays”:
feedback is patched outside, g0 has no internal feedback.
and as soon as you change the pitch of the g0 the grain width changes proportional to it.
with this test i combined these things and sequenced pitch and grain width to a very simple incoming sequence:
the three ascending notes is the dry input, the rest/second voice is pitched live g0.
i use it mostly like this, it’s easy to double the voice and have very strange results by changing the grain width and pitch of ultra simple sequences to make them instantly more complex and chromatic!

Just got my g0 today. As with the d0, I think it will be some time before patching becomes intentional but some happy accidents already.
I was curious if anyone has been able to get any reverse delay type effects with the g0 in live mode? Is that possible?
Edit: I think I figured it out. Using the reference out of my Verbos multistage (which is a ramp down envelope the length of the stage) into the buffer start position with inverse attenuation, short grain length, and pitch high. Need to test with vocals or something else with a definite direction. This thing is amazing!

exactly! a sawtooth wave moves the playhead forward, a ramp wave backwards, but since the attenuverter can invert incoming cv it doesn’t matter what wave you take. the grains are still played forward, only when the grains are very small this backward sound comes through…which is very cool and weird especially if you modulate grain width in and out of this recognizable backwards effect!
edit:
my own reply made me think about how this would work in live mode…the reverse thing. and now i got some headache! regardless of playhead and grainsize, the audio moves forward since audio is coming into the live input. if i then add a slow ramp to grainposition and have very small grains…i basically stop the playhead. i imagine this as a tug of war, two opposing forces. as soon as i freeze the g0 the audio gets reversed.
anyway, i definitely don’t understand the scaling of the depth cv (linearly scaled in volts per second says mungo), it reacts to the speed of the ramp/saw and to it’s voltage…it’s so difficult to figure out how much and how fast of a ramp/saw one needs to scroll through the complete buffer. if it’s too much then the last grain gets repeated over and over, but since there’s no clear zero it’s awfully difficult to find the exact spots…

thanks for the detailed explanation, I start to understand it better (until I turn on my rack the day after 
)
I’m dreaming about a simple bipolar led to indicate the range/offset of voltage of each parameter after scaling. So simple to diy in the analog world…
yes the g0 really needs some visual indications!
here’s a try with the above described settings:
live input reverse playback. first with spoken word then with a simple tone sequence.
i switch between freezing the g0 and let it run freely, but all the time it gets a ramp wave into depth cv so it wants to play in reverse. it’s definitely not a clean reverse playback, but i’m still fascinated by this.

did you do a short trip in the black lodge to record the first part… ?

i just don’t understand how it works honestly… i imagine it as tape recorder/player with record and play head but there are constant collisions of those heads and no clicks are audible and also the latency is extremely small…

All-round clicklessness is among the crowning achievements of this magnificent module.
I’ve little energy for composition or arrangement these days, at least at times when I actually have the gear before me, so often I find myself just using g0 to examine arbitrary samples in minute detail, scrubbing with sloths through harmonically interesting textures. I can listen to just that for tens of minutes at a time. So satisfying.

good to know that the g0 is very forgiving in terms of clicks.
somewhere here i read that th g0 does not perform straight granular synthesis (at least by definition),
i.e. playback overlapped and windowed grains of audio.
iam really curious how the g0 does the playback than…cause it sounds so good.
does it overlap audio at all?

There’s no overlap, just a single looping playback window. It seems to me that ‘granular’ modules in Eurorack either manipulate single windows like this (e.g. SDS Digital Reflex LiveLoop, which is stereo and offers different windowing modes, but is clickier and works at a coarser resolution - I still loved it when I had it, mind) or allow playback of several or many simultaneous grains - the Clouds/Arbhar/Disting EX/Cornflakes style, arguably more popular, more familiar as derivatives of softsynth granulars and generally more what people expect from granular samplers). For what it’s worth, I think because g0 does the single-window thing so well is one reason it remains viable and can sound quite distinctive.
Edit: Mind you, all these various devices can have their own good characteristic sound, whether course or fine, mono or stereo, one grain or many. It’s such a great type of effect.
Edit for future reference: I’m wrong about overlap; see below.
there’s a crossfade between grains. when grains are small, the crossfade is short too and almost inaudible, with longer grains the crossfade gets longer too. i measure it once without cv and the longest grain was 12 seconds with an crossfade/overlap of 9 seconds to the next grain. but definitely no polyphony with the g0!
