Trill_SC on Gem Multi

nois

Hi. I´ve been working on a project that involves the sc trill ugens made by jreus on a gem multi but i´m getting the same underrun problem when i try to run the examples and my own patches, even if they are overly simplified just to get readings:
TrillRaw CTOR id: 281473713536320 Trill sensor found: devtype Craft, firmware_v 3 Found 0 active Trill UGens Initialized with outputs: 30 i2c_bus: 1 i2c_addr: 48 mode: Raw thresh: 0.0400 pre: 2 devtype: 3 Underrun detected: 440 blocks dropped at 103872 1.697s Stopping Bela ... SC_BelaDriver: signal received: 2; terminating Program crashed with Segmentation Fault. Backtrace: make: *** [Makefile:745: runide] Interrupt Bela stopped

I even tried to modify a couple of things in the TrillRaw.cpp in order to get less readings but the problem persist so, can you help me with this?

try starting scsynth alone and see if you get a more meaningful error there:

scsynth -u 57110 -z 16 -J 8 -K 8 -G 16 -i 2 -o 2 -B 0.0.0.0

Then connect to it from sclang (e.g.: from the host computer) and see if you can cause the same crash

I got this:
scsynth -u 57110 -z 16 -J 8 -K 8 -G 16 -i 2 -o 2 -B 0.0.0.0 SC_BelaDriver: >>DriverSetup - Running on PRU (1) Configured with (8) analog input and (8) analog output channels, (16) digital channels, and (0) multiplexer channels. HeadphoneLevel (-6.000000 dB), pga_gain_left (20.000000 dB) and pga_gain_right (20.000000 dB) DAC Level (0.000000 dB), ADC Level (0.000000 dB) oscilloscope channels (0) Speakers are not muted. SC_AudioDriver: sample rate = 44100.000000, driver's block size = 16 SuperCollider 3 server ready.

so it´s running ok. I found that the audio stream is not the problem because scsynth works well, also the craft i´m using works well in c++ and pd projects but if i run the trillcraft example from jreus i get this:

Hmm can you run scsynth within gdb and make it crash? That should tell you where it fails

giuliomoro

What repo were you using? I just pushed a built version to my repo: https://github.com/giuliomoro/Trill_SC , which is now 26 commits ahead of the upstream one. After a quick test, it doesn't seem to crash.
