Is it absolutely impossible to ever see a DIY loop station project ?

I guess a diy loop station would cost more than the cheap products on the market, like Nux Loop Core at 100 euros, or TC electronics Ditto Looper at 75 euros.

But i think a diy project still could be interesting.

I wonder if it's just the cost efficiency that is the main issue, or if such project would involve some parts for the memory that can hardly be used in a diy build ?

Is it a technical problem, or is it the competition with cheap industrial products that explains the lack of recording devices in the diy community ?
 
There are some lofi loopers with isd1820 chips.
This fuzz for example is also funny with a loop button:

Subspace

Subspace Transmission is a fuzz with a recording and playback feature based on the ISD1820 voice recording chip. It can record up to 20 seconds and the playback can be repeated and pitched up or...

My guess is that such a project would need a chip with significant memory and some custom code. Something like the Daisy seed would probably do. So I guess you could use that and write your own code…

20 seconds ?

I'd be frustrated. Even the cheapest loop station on Thomann can record 5 minutes.

5 minutes would be a minimum, 10 or 20 would be better, and a few banks would make it an interesting tool. Being able to save a track and go to track 2 record something else, for exemple.

I dont know anything about the suitable memory ICs, but i guess it would be all smd, and not really ideal for a diy build.

I guess that's why it hasn't been done already by Madbean or some diy pcb designer ?

It's not impossible, it's only a matter of time...

oh ?

We can count on a PPCB loop station in the near future ?

Will it be stereo ?

Will we be able to record one track on the left channel, and an other in the right channel, if we plugg the cables accordingly ?

Will it feature some sort of complex footswitch with different response if we press twice or if we keep pressing the 3PDT ?

Glory !

Glory to PPCB !

Maybe we could imagine some sort of "modular" project.

A recording circuit designed to be used on its own or implemented in a larger build, with several other similar circuits ?

If 1 Daisy Seed can store 10 minutes, maybe we could put 2 or 3 of them in a big box, and be able to play them simultaneously ?

Each Daisy Seed circuit connected to its own footswitch...

I mean, the possibilities are infinite, we could put as much Daisy Seed circuits as we need, as much tracks as we need, all in one box, and be able to record and play several tracks... Just like the most expensive circuits from boss !

Maybe even some toggles to connect the circuits together and record 1 loop over another, or keep them isolated...

You need the 65MB Daisyseed, which is around $30. I have spare funbox boards if you would like one. Also, the funbox creator is on these forums - @keyth72

There’s an ongoing thread with plenty of info about the funbox:

keyth72

EXAMPLE Thread 'Developing a custom pcb for Daisy Seed - Funbox'

Usually when I set out to make a new guitar effect "thing", I develop it in a vacuum until I think it's ready, and then I'll share the finished product. This time, I thought it would be fun to document the development process, and bounce ideas off the community.

These are the current goals/parameters for the project:

- Daisy Seed based 125B pedal to have as a base platform for multi-effect modules, and testing new DSP ideas
- Stereo in/out
- Midi in/out (mini trs) OR Midi In / Expression In
- Controls: 6 knobs, three 3-way switches, two footswitches, optional outboard dip switches...

Thanks a lot, that's very kind of you !

I'm in France and i guess the shipment fee would make the project a bit too expensive.

I'd rather buy an ic with the program already written inside it, i dont want to deal with digital programing, etc. I wouldn't know what to do with an empty chip.

I already have a few loop stations and im not in a hurry.

This project looks very interesting, but im used to build kits from musikding, and i ll rather wait for PPCB to make a board and pre-programed ICs that they will sell in Europe in colaboration with musikding. This way it's 10euros shipment fee instead of 30 or 40 from the US, and diy projects make more sense.

Robert said it was "just a matter of time", right ?

I'm glad to see that recording devices aren't out of reach for diy builders anymore.
 
@eh là bas ma Someone else was just asking about a looper, here's that forum post:

keyth72

Post in thread 'Looper for Terrarium'

This is one I wrote for Terrarium, it has abunch of other effects in there but you could strip those out if you just wanted a looper. Press the footswitch once to record, once to stop recording and start playback, and repeat for overdubbing. Double tap to pause playback, double tap again to resume. Hold to erase the loop. It will slowly pulse the LED while recording, solid LED while in playback, and blinking LED while paused. It also uses one of the toggle switches to put the loop into reverse or forward. I think I put something crazy like 5 minutes of max loop time, since I'm not using...

Yeah the Daisy Seed is probably your best option for a DIY looper that I'm aware of. I have one of the older versions of the Ditto Looper, and the Seed code that I wrote for Terrarium has a looper that does what the Ditto does. The only exception is that there isn't an "undo" function, but that is definitely do-able with some additional coding.
 
I can second this. It also has the benefit of being able to run the code using a very small block size. ( If you deep dive things Daisy you will find out what that is about )

I made a daisy based delay that locks the buffer in an infinite loop like the old blue Digitech PDS delay pedals.
Not 100% sure but I might have thrown that up on github. The build doesn't use any carrier PCB, just a perfboard. ( Looks like it follows the Terrarium hardware definitions. )

Edit: Code is there and it looks like what I remember doing last. ( Of course, I don't remember what I ate for dinner yesterday. )
