This is exactly what I've been looking for

This is exactly what I've been searching for (although to be honest, I'd ideally not have to build it myself..!)

So a few questions:

1. What is the latency like?
2. How easy is it to build? Would I have to buy a soldering iron? I just have screwdrivers and stuff. I am "good with my hands" but only have very basic electronic experience.
3. Does it really work straight out of the box (with the flash image)?

More questions:

1. Is there a circuit diagram for Raspberry pi 3?
2. How well does the beta ISO image for raspberry PI 3 (here: http://www.samplerbox.org/article/summer2016news#disqus_thread) work?

1. Are there any super clear instructions for idiots for both software and hardware out there anywhere? I'm probably going to give this a go, but as it's my first project, I want to do it as simply as possible.

Hey Josh,
Neat project huh!

• Latency is negligible, ~2-5ms.
• If you tweak the midicallback section in the samplerbox.py you can get away with no soldering at all and navigating presets with a midi controller.
• Should work straight out of the box! (it's been a while since I started from scratch). I'm using a RPi3 - the installation on my SD card was compatible between my Pi2 and Pi3.
• If you want to go a little further, Hans has some very good instructions for his modifications: http://homspace.xs4all.nl/homspace/samplerbox/index.html

Hi alex, thanks for your reply. I could probably borrow a soldering iron from a friend. Is the circuit diagram the same for the raspberry Pi 2 and 3? I'm not sure what difference there is...

I'm pretty sure it's the same for RPi2 v RPi3. Hans' connections to the GPIO worked for me (I think his project is on a Pi2).

I'm very much the same as you - limited experience with electronics, but I got a grasp of it pretty quick ;) ps I hope you're not planning to solder the Pi itself!

I bought everything I need, but i didn't get the breakout microUSB for power because I couldn't find one that wouldn't involve soldering (and i think I can do the whole thing without soldering, which is great).

My question is, what does that secondary microUSB actually power? I see the raspberry PI 3b already has a power input. So..?

If you're following Joseph's instructions, that breakout microusb is just so it can be positioned where desired on the box, so it's not necessary for it to work

I am stuck on this. I am using a power supply that came with a raspberry pi kit (should be powerful enough!) but i'm still not getting any power to the USB slots. Any help for a total beginner?

The power supply, which was sold as "power supply for raspberry pi 3 is DV5V 300mA. That's not powerful enough, is it?

Got it!!! OS wasn't installed properly. I can't recommend the open-source programme "etcher" for installing IMGs to SD cards. Worked perfectly on my mac.

Here are a few things I'd like to change.

1. Some distortion going on, seems hard to predict when (has to be software, it's too unpredictable to be a hardware problem). I am using an USB DAC.
2. The automatic pitching up (if you just put it one sample, for example) doesn't really work for me in the situation and I know i'm going to get confused about that later.
3. I need to get a screen and some buttons.
4. and make a case!

I am very impressed!!!!!!!!
