I did find that thread when looking around for the realtime priority configuration options for Jack. It was useful. But, there is only so much horsepower the Pi can offer. One thing that gets overlooked is the multiple cores the Raspberry 3 offers. If Jack could be compiled to take advantage of that...

The latency is indeed high and I wouldn't use this for a lead melodic instrument the way it's set now. It's mostly for pads and textures. It's set that high because I get pops/clicks when certain instruments have 3-5 keys pressed. Keep in mind it's also serving a Node app with express, so I wanted t...

I got ZynAddSubFX running on a headless Raspberry Pi 3 with a Pi-DAC+, along with a small web app to switch instruments served over wifi. I thought I'd share this tutorial and video I put together so that others can try it out. Sounds great.

DIY Raspberry Pi synth with ZynAddSubFX

For those interested, here is a tutorial I put together to get ZynAddSubFX running on a Raspberry Pi 3 in a headless configuration. It incorporates the info we found through this thread discourse. https://lucidbeaming.com/blog/setting-up-a-raspberry-pi-3-to-run-zynaddsubfx-in-a-headless-configuratio...

I don't use darkice or know anything about it, but here is a general setup for a Raspberry Pi and alsa/jack. Set your USB card to be the default device: sudo nano /etc/asound.conf pcm.!default { type hw card Device } ctl.!default { type hw card Device } sudo reboot Notice I used the reported alias o...

Put some distortion on the guitar from Reading Book into Night and add some detuned drone pads in the back, and you'd have a sweet doom/dark ambient song.

Bluegrass and Southern rock. My dad is a really good banjo picker. He gave me a mandolin when I was a kid, but now I only use it with an EBow to get harmonic drones. Here is one of the songs I made with his mandolin, contact mics and an outboard reverb pedal.

I built my own using a Raspberry Pi and Fluidsynth. Lets me load up multiple independent soundfonts and create a bank of just the instruments I want. Even has a basic display and instrument switcher. Here's a video I made of it to demo the sounds. My latest iteration is running Fluidsynth on a Pi Ze...

Ok, a few OSC goals for this small web app. What I'd like to have is a simple way of switching effects on and off on a global level, as well as basic filter cutoff, resonance, and global envelope control. Some of that is for expression, but also to simplify complex instruments that give XRUNs when p...

Ok, lots of trial and error and compiling with various options. Was about to give up. But, I have a stable build running now. Your suggestion of 'NoNeonPlease' didn't work by itself, but it reminded me of a problem I had with an old version of Zyn that was trying to compile using SSE2 and would fail...

I tried running it through gbd again, now that its recompiled with BuildForDebug. Now it changes instruments without crashing. I am at a loss to explain it. I did a backtrace anyway, so you can see if there is any difference. Although somewhat good news, I have no doubt that if I started over with a...

Ok, rebuilt with BuildForDebug, installed valgrind and tried your suggestion. Got an error. $ valgrind --log-file=valgrind-output.txt /usr/local/bin/zynaddsubfx -U -A=0 -a -o 512 -r 48000 -b 64 -I alsa -O jack -P 7777 -L /usr/local/share/zynaddsubfx/banks/Fantasy/0034-ImpossibleDream2.xiz Illegal in...

Fresh git compile on a new os install, same problem. Below is the gdb backtrace. Bummer.

They have been compiled from the tar files from Sourceforge. What concerns me is that the same issue happened on a compile of 2.5.4 I tried on a fresh install. That 2.5.4 version worked fine compiled on arm Debian back in June 16. I will try a fresh install and git compile tonight. Will report back ...
