coco: skip / sync

Post by arnoux » Wed Jan 13, 2016 5:26 am

Hey boys and girls,

(edit: read below for a practical solution)

can we discuss a bit how the skip function works on the Cocoquantus?
The internet says "mark a place/step back to it" but what I can hear, if I feed in there a quantussy oscillator, is my material stepping back, yes, but where? How do you mark a fixed, stationary point?

Thanks in advance for your time! :banana:

a comparator
so whenever the input signal goes above a certain threshold it marks a point then when it falls below that threshold it goes back to the marked point

on lineage coco instruments there was an "ip" knob which changed the threshold point of the comparator now it is static I assume somewhere around 4.5v

Thanks for your reply wednesdayayay!
Anyway it's still hard to get the point.

How can I get it always resetting to the same point? So to sync it somehow to an external device in a more calssic loop fashon? Can't try at the moment with an external sequencer but: you mark The point with a 4.5V pulse and then reset to that point with a lower voltage note ("ereasing" the 4.5v message from your sequence)?

Am I talking bullshit?

It won't be precise but you could use a square wave with pulse width manually set then manually tune the reset point... Like I said it would be hard to do but it should get you closer to a traditional loop...

Interesting experiment...

I do wish Peter would have left in the IP knob from the old Cocolasse... I've asked before if anyone techy could add a knob to the new Coco2's to get the same effect but no one seems to know if it would work... and Peter never replied to the question...

yes IP knob would be awesome

http://ciat-lonbarde.net/cocolase/man/index.html have you read this link about the coco lineage?
the "to, fro" picture is in reference to this IP knob topic maybe that will help

I'm fairly certain that if you use a comparator on the signal going in (from a traingle/ ramp wave of course) you can change the "ip" setting. I have yet to do this though.

Thanks for your reply, this topic requires deep investigation, at the moment I'm just feeding the skip in with a grey output from the Quantussi (castle?) having the loop jumping around in a random fashion..

Any suggestion on a different approach?
May I ask how are you using yours?
Can't wait to try with my Cirklon but at the time I'm missing the right cable..

It is more repeating or almost granular sounding when you send a nice even triangle wave into the skip

But if you want utter madness try using a cocoa gray output into its own skip input

I've got a CQ2 pcb that I'll be building an enclosure for and getting all the inputs and outputs to be at synth level, a-la Pugix's Modular Tetrazzi... An IP knob is something I plan trying to implement. I love it on the Cocolase, and it really does allow you to dial in a segment of the loop.

Thanks for your replies, I can't get it totally, I'd have to get my hands dirty.

Basically you set a threshold at say 4.5V, when a square wave or voltage hit that threshold the reset point is marked, you can do this with a sequencer setting the steps at say

4.5V 0V 0V 0V 4.5V 0V 0V 0V 4.5V 0V 0V 0V 4.5V 0V 0V 0V

When the reset point is marked you uplift the threshold level so when the sequencer hits a peak the loop "reset" to the marked point?

Isn't the same to lower the voltage on my sequencer so a settable comparator is not needed?

Am I off the mark?

If i may piggy back on this thread and think out loud...

But Couldn't the xlr or Piezo inputs and their corresponding amplitude knobs be an IP knob in a sense? I've never wiggled an IP knob so this is all theoretical.

I have been thinking of some easy ways to use the xlr/Pizeo outs to better sync the two speed and affect knobs for a more precise delay.

Also, The fact that after my previos post I thought "hmmm a banana to xlr cable..." Jesus the coco is great. Is this even a thing? So many ways to think about this machine/thing/ghoul

Here's an experiment using audio to sync a loop

[video][/video]

Patch notes to get the job done:
OP-1 -> "Piezo" Audio In
White Audio Out -> SKIP ( -> Coco Green Audio In )
Orange Env Follower -> Flip

The "click" (audible on purpose) must be "loud and tight", I used a rim-shot amplified at +24, pitched +33 (to shorten it).

(Too much) reverb added later on ProTools.

Loop will slowly drifts a bit during time, you start to notice the drifting after minutes. If you set the audio click at 1/16 the drifting is immediate but super cool.
But Couldn't the xlr or Piezo inputs and their corresponding amplitude knobs be an IP knob in a sense?
Mashmore this was exatly my thought preparing the above experiment.

well shoot I was hoping to never see effective usage of the new envelope followers as this really gets me wanting to trade up or get a second coco

Great work man! Gotta try this!

Sadly, the SKIP IN of my right Coco doesn't work anymore. Hope I can fix it, as this changes the Coco a lot for me.

Ha, it works with a pulse from a TR606! So now I have synced loops that I can feed via clock dividers. Arnoux, thanks again!

I'm going to try to KORG sync application
as if that works it should mean the volcas into the skip input would work as well potentially right?

Hainbach sorry for your Coco :waah: hope you can fix it quickly!
Glad it works with your 606, can't wait to hear what you're cooking!

wednesdayayay hope what your're thinking works for you :tu:

arnoux I finally tried this trick and it works amazing! It's nice cause you can let it drift a little by sending multiple triggers to sort of confuse the IP setting so you can bounce around rythmacally... I'm not big on using drums sounds but I'll post my little experiment on SC when I get into the studio to show the fun... Thanks again for this tip :nana:
