Help using rock band drums on raspberry pi. Recording Sound on the Raspberry Pi. The Raspberry Pi does not have a microphone socket, which is inconvenient when you wish to record sound. To fix this you will need a USB Sound Card, for which I bought a Creative Sound Blaster Play! For about £20 and a short USB extension lead as the sound card is slightly too large and blocks the other USB port. With the latest Raspbian “wheezy” installed on a Pi Model B with 512Mb of RAM and the overclocking set to High in raspi-config, here is a recipe for getting your Raspberry Pi to record sound from the command line. For the test setup I connected my iPod to the microphone port of the sound card, plugged everything in and powered up.

After logging into the Pi, check that the computer can see the card, use lsusb to find it, here the card is highlighted in blue:$ lsusb Bus 001 Device 002: ID 0424:9512 Standard Microsystems Corp.

Looping pedals are mostly not very cheap. You might want to look into getting a used pedal or an open-box item. Digitech makes a less expensive pedal than Boss and they also include a looping function in some of their newer multi-effects pedals. If you are looking for something to record you own guitar then you are pretty much stuck in the > $100 range. If you are willing to do a little more work on your own and just want a backing track then there are fairly inexpensive options. In Make magazine, issue 26, there is an article on how to make a Luna Mod Looper.

Link: They used a PICAxe microcontroller but any of the following microcontrollers are easy to get up and running: Arduino, Basic Stamp 2, and PICAxe (as mentioned). Links: The last two links are of the latest prototype. There are other people whom have made loopers and samplers using microcontrollers. Raspberry Pi, Pure Data, MIDI, Meh » Blog Archive » DIY Cheap-o Looper Effect. March 23, 2008 – 2:39 pm … I’m surprised with what I’m able to do when I’m supposed to be doing homework. Here’s my latest project, it’s less than 24 hours old =) I’ve always wanted a looper effect, like the boss loopstation, mainly because the online demos were so neat.

Being a bass player, I though it would help me practice with drum loops, but it’s just not worth the money unless you’re going to use it live. I ended up playing drum samples on my PC and playing along on the bass. more (and video) after the break About 2 weeks ago, a friend asked me about creating a digital recording circuit, for a project (which will be posted here when completed, going to stay a secret for now).

Some online searching brought us to a keychain digital recorder product. Yesterday, we met and started to disassemble and test this unit. This morning, I had a day off work, and decided to continue this little project. And here’s the simple arduino code:
