Re: Eliminating pops/crackles in USB audio with JACK and SooperLooper

Thanks. pulseaudio wasn't installed. I did install Samba so I could easily transfer or access the recorded WAV files from my Windows machine. Seems like at least some of the crackles are in the recorded WAV files.

Eliminating pops/crackles in USB audio with JACK and SooperLooper

I have a Pi 3 Model B 1.2 mounted in one of those 7" LCD touchscreen cases. I have modified the GUI code for SooperLooper http://essej.net/sooperlooper/ to hide some of the features which I never use and make it possible to display 3 looping tracks on the LCD. This is all working quite well. I am us...

Re: Trouble executing SooperLooper GUI via VNC

Well, I wish I understood why this happened, but I rebooted and it went away. It had nothing to do with using VNC as the exact same thing happened when I was connected with a keyboard. So now I'm able to edit the SooperLooper UI! :D :D :mrgreen: :mrgreen:

Trouble executing SooperLooper GUI via VNC

I'm pleased that Raspbian includes SooperLooper in the default repositories. I set up my Pi 3 with one of those 7" LCD touchscreens, connected a Behringer UMC-404 HD audio interface and a Macmillen Softstep MIDI foot controller. Routed a couple of MIDI and audio connections using QJackCtl, all worke...

Re: Pi 3 Jessie, PyGame audio just outputs clicks

Update... I rebooted to CLI. Makes no difference. I think my comment about 48000 WAVs working better than 44100 Hz ones was off. I just had downloaded some 48 kHz WAVs which were longer, so I could actually hear most of them. But since I wasn't familiar with what was in them I did not perceive that ...

Little history here first. I have a couple Raspberry Pi "A" models which I think were from the second shipment ever.

The main reason for getting a blank screen on a Weaved web connection is simply that the web server itself is not running or is perhaps on a different port internally than the Weaved service was configured for.

Re: XMOS multicore microcontroller dev board giveaway

Interested to see what you come up with. Am following the Xmos kits as one of their engineers has done a fair amount of work in creating audio effects (e.g. for electric guitar) on it. He's been talking about the possibilities a bit here.

What's your strategy for developing and deploying on the Pi?

I've written a few programs for the Pi in Python. Loads of fun. Up until recently I have been checking the source code into a SVN repository from my Windows 7 PC, and then using some scripts to checkout certain source folders from my Assembla repository down to the Pi. So there is a working copy on ...

Re: Confused about Python classes

I updated the code, it now does spirographs and harmonographs. I also built in a "sequence" mode that takes a specific curve and iterates through a set of incremental drawing parameters, specifically phase and damping, so that you can see these curves appear to rotate in 3D. Right now it just genera...

Many years ago I needed a pseudo random number generator for 16 bit values in an 8031 based system I designed.

I'd tend to agree it's not suitable for that age.

Which is some, for sure. That said, my Pi keeps track o...
