Hi there,
Sorry for my slightly slow reply, I just got my RPi3 setup, and am having the same crashing issue...

The Pi is amazing for musicans who travel a lot. There is this samplerbox.org project - amazing with an keyboard / drum pad.
But I found a soulution wich is quite OK for the moment.: On the Raspberry Ubuntu Image with Mate Desktop there is a stable and well working version. The only issue is that the environment itself is very slow. Maybe there is a way to use this version on Raspbian because both are based on debian? hmm
p.s. If I find a solution I will keep you up to date
I haven't tried Ubuntu Mate on my RPi3, but I got annoyed with the sluggishness of it on my RPI2. So when I bought my RPi3 last week to create a portable software sound module I opted for Raspbian Jessie which I must say as an OS is not as pretty as Ubuntu, but is vastly more responsive to input. Sadly though I have the same segfault issue with LMMS 1.0.3.
The segfaults that usually happen look like this through gdb...
Code: Select all
Program received signal SIGSEGV, Segmentation fault.
[Switching to thread 0x70fff3d0 (LWP 1548)]
0x0011b2a8 in AudioPort::processEffects() ()
These segfaults seem to happen randomly although almost never right at or just after startup, its usually a minute or 2 in sometimes longer - I can be playing SF2's via a keyboard, or programming drums using the mouse, or LMMS can be sitting there not playing at all - it just vanishes or freezes. The longest it has run for was when I set a beat running and stepped away as a test - it ran for 30 minutes, so I stopped the beat and walked away, and then came back to the Pi 5 minutes later to find LMMS had vanished/died while sitting not playing!
Other than that LMMS seems to run very smoothly - latency is minimal, I can play *most* of the demo songs without overloading the RPi3 - I have 2 x USB MIDI controller keyboards attached (M-Audio KeyStation 88es, and Novation LaunchKey 49), I use a Behringer UCA202 USB audio interface for audio I/O, and since the SF2 player takes very little CPU I have 8GB of soundfonts (ranging in size from 5MB to 300MB, some very nice ones) that I use to make noises - if the segfaults could be solved it would be the *perfect* twin keyboard setup for jamming, which is kinda what I was hoping for as I jam fortnightly with some guys from work.
If there is anything I can do to help solve the segfault mystery I'm keen to help...
Cheers,
Chris, NZ.
