UART problem when data is already arriving during boot

Hi, I'm using UART Rx since years, because of the project I started : http://www.samplerbox.org , to add a MIDI IN to the RaspberryPi. I wrote this guide 2 years ago. The new method: enable_uart=1 dtoverlay=pi3-miniuart-bt dtoverlay=midi-uart0 works great :), far better than the old hack with init_u...

Re: Analogue audio testing

@jdb, is it possible to make the driver natively work as 44.1Khz? (instead of 48khz) Context: I'm the author of the project http://www.samplerbox.org (Hardware sampler based on RPi, see here ). Even with the new driver (which, by the way, is a wonderful step for audio on RPi!), the software SamplerB...

Re: Raspberry Pi based Synthesizer

As I wanted to have a "Rhodes" piano with a Pi, I tried myself SoundFonts on a RaspberryPi a few months ago (with fluidsynth, etc.), and came to the conclusion that it is impossible to have decent polyphony (more than 20 voices for example). Then I started coding my own sampler, and finally ... it w...

Re: Raspbian official image

Then, where is the official image, done by Raspbian project ? There isn't one. The official image is the one made by the Foundation, using software from Raspbian. The Raspbian people provide a software repository. They don't provide pre-built images. One reason for that is that the images contain e...

But we end up again with a forum post with lots of things to do, lots of possibilities, various links to follow...

@moderators, could we do a short sticky post, with the easy and short solution to have a clean Jessie Raspbian?

Re: Jessie ready-to-use image

Raspbian Jessie is still in Testing and the RPF will announce, like everything else when ready.
Is there a Testing Jessie image?

(instead of having to install Wheezy + then upgrade, it would be cool to have a Testing Jessie image)

Jessie ready-to-use image

Hi, There is a lot of Jessie-related topics, and I read some of them, but it's easy to get lost with them. So here are two questions: 1) Will there be an official Raspbian Jessie read-to-use image available here: http://www.raspberrypi.org/downloads/ If not available soon, is there a release candida...

(silence) python test.py (now background noise is x 10) ... after 10 seconds (now the background noise is stuttering!) Do you have the same behaviour on your RPi? How to hav...

Goal: to be able to play a Piano soundbank, a Rhodes soundbank, etc. with a MIDI keyboard connected to the Raspberry Pi. I am currently working on a software sampler project (that allows to play .WAV with a MIDI keyboard for example), based on Python + C (for time-critical operations) that already ...

Re: ALSA on Raspbian

I have similar problem when trying to list audio devices on my RPi B + Raspbian with Python + PyAudio. This Python code: import pyaudio p = pyaudio.PyAudio() for i in range(p.get_device_count()): print p.get_device_info_by_index(i) produces this dirty error. Do you know how to solve it? Any idea @de...

Sound quality on RPi2 ?

Hello, I have a RPi B and the sound quality is not so good . [I don't remember where, but I think I had read it is 12 bit or 11 bit PWM or something like that, that I don't know ;) ]. I'm about to buy a RPi2, but first I would like to know if the sound quality has been improved. My plan is to build ...
