My first venture into raspberry pi stuff. Running a custom pure data patch I've been working on for a couple years on a Raspberry Pi 3. This project took a couple months and I'm still tweaking stuff here and there but it's pretty much complete, it even survived it's first live show!

C++ 100.00%

raspberry-pi-looper-synth-drum-thing's Introduction

Raspberry-Pi-Looper-synth-drum-thing

I've left out the drum samples and Sessions directoroy. To add your own samples just add .wav files to the piLooper directory with names like:

kick_01.wav - kick_24.wav

hh_01.wav - hh_12.wav

snare_01.wav - snare_24.wav

crash_01.wav - crash_04.wav

Or change the sample names to whatever you want in the pd patch. The Sessions directory is pointed to where it lives on my pi, you will need to change that to wherever you are storing your patch on your pi.

You will need comport and shell externals in pd.

raspberry-pi-looper-synth-drum-thing's Issues

reproduction for school

Hey. I'm trying to reproduce this for a school project and am wondering if you had a wire schematic or anything like that. Also, I'm pretty much new to all this stuff so any advice/links to sources for learning about how to do all this would be extremely appreciated

Repo questions

From looking at the repo, I am assuming that piLoopControl.ino is the code for the Teensy, and that everything in the piLooper directory goes on the RaspberryPi. What code are you running on the RaspberryPi?

Can you provide the schematic

Hi, I was wondering if you could provide the schematic.

Please pick a license

Saw a video of yours on YouTube that'd been posted to Reddit. Very cool project.

Please pick a license for your repo. I suggest choosing the ISC license. The ISC license is similar to the BSD family of licenses, except it has some text removed that was determined to be not necessary. The Pure Data project is using a modified BSD license so the ISC license probably aligns with your views on open source.

Choosing a license allows others to easily and confidently know what they can and can not do with the things you've released.

Here is a copy of the ISC license: https://gist.githubusercontent.com/eriknstr/84c5c986607f3e4245991480a40e2c45/raw/d998764c0e914964a380b74b28332ea0c7ca28e7/LICENSE, replace YYYY with the current year (2017), "John Doe" with your own name and [email protected] with your own e-mail address (keep the angle-brackets). Alternatively if you do not wish to include your e-mail you can just remove the placeholder e-mail and angle-brackets.

Second display missing from BoM

Hi,
Fantastic build btw. It appears to have 2 displays but you only have the Teensy tft in the BoM. Can you add the Pi3 one?

Some basic questions

Hello Otem. Great work.

I'm attempting to recreate and I'm documenting my steps. I have a few clarifications and a question. Would you like me to publish them here or somewhere else?

Are you running Pd 0.48-0 "vanilla" with only the comport and ggee extensions? Or a different version of Pd?
On the PRI are you running Raspbian Jessie? (Stretch is now the default for new Raspbian installs).
On the Sparkfun push button boards... for the loop control buttons (8 buttons)... Did you cut down the larger 4x4 board or did you use (2) of the 2 x 2s?
Currently, I'm stuck getting serial communication working between the Teensy 3.6 and the Rpi. -

I've identified that my serial port on the Pi os "0" when yours was "1".
I changed the object in serialControls to read comport 0 9600, but I still get the following error scrolling rapidly in the Pd Console"
[comport]: "Write failed for 0 bytes, error is 11" (once it was error is o).
I've confirmed the Pi is part of the DIALOUT group that has write privledges to /dev/ttyAMA0

Did you have to stop getty on the serial port or anything like that?

I'll continue to work through this. If you have any tips, I'd appreciate them. Thx.

Effect patches

Where can I find the effects in this pure data patch?
