Guitar looper (sampler) possible? can't find any active project

[fatecasino]

Hi all,
I have been searching for long for a simple looper project, something to record and play along.
I am not searching for something super hifi, just to be able to record 40-50 seconds of guitar and then repeat it eternally. I have tried many things sold in the ebay (even Christmas cards with voice module) but nothing that can do the work. Their main problem was the autorepeat mode which has to be precise, otherwise it has no musical sense.
On the other hand I don't mind for sound quality, it should be something simple to jam or study with.
I have oriented my search towards arduino projects but even there I wasn't able to find something.
Any ideas?

Raspberry Pi.

The Pi3 just came out and I have one on the way.  I'll update you when I see how it does for RT audio out of the box, but I do see there has been some success on previous models with this kind of thing.

You can use the IO pins to do stop/start functions when wired to buttons.  Should fit into a reasonably sized box.  It has tons of RAM, so record time could probably be even several minutes worth.

I haven't tried this, but this looks like an interesting project:

I tried to find something like that about half year ago. So i just bump in for notifications.

I ended up buying a MIDI footswitch and i'm currently using a software looper (Möbius 2). It covers a lot more than i first thought and i might be able to create live setups with it.

Not sure it will suit everyone's needs re time and quality but this looked like a fun project when I saw it.


Thanks Bear

It looks great, but I can't find any demo video. It's not cheap, but I would risk it if I knew how it loops over. When reaching the end of the loop does it have any latency time to start over or it replays the sample instantly. This is a very important feature, if it takes some moments to replay the sample then it would be impossible to jam with it. I suppose it records just one layer, i.e. you cannot record several layers on the same sample.

It does not "loop over" automatically as shown. Unfortunately, I can't tell you for sure whether an auto-repeat function added through the button inputs would do what you need.

Can't you get a Ditto Looper for fairly cheap these days?  I'm talking the original one, with just the one button.   I'd imagine they are quite reasonable on the used market.

If nobody else mentioned it I was going to bring it up. I got my Ditto (the original single button one) for $60 shipped, and it does everything I would ever need a looper to do and more, plus I didn't have to program it or debug it

I'm expecting Rob to chip in here.  He bigged up a super-cheapo looper - "Nuxx" as I recall.  There's bound to be one of Rob's demos if you search.  And doubtless our fave spaceboy will be along shortly to elucidate...

[deadastronaut]

yep, i'm here....

yeah the nux is very cool... and very cheap too...around 65-70 quid..

6 hours of recording...99 loops...aux in too...drums...blah blah blah...

you will want to build the ''optional'' but essential imo, control footswitch too
for live stuff..

Unfortunately looping/sampling and "simple" don't go together. For a truly looping looper, there's the payback (search for it, there are a few versions on the forum). It's answering-machine audio quality. Anything better and you have to go the programming route, either arduino or your own choice of IDE and programming language.

I've done it, but it was far from simple.

when I said simple I meant with simple features, just to loop over let's say one recording. I am good at arduino programming, I you know any project please recommend

I dont think there is an active project because it isnt really worth the time an effort for most people.

If your proficient in arduino code, why not create one? You can start an host the project.
