donut's Issues

Dumps core on attempt to use

Was eager to try out donut!

Sadly, after connecting my MIDI keyboard from the menu and hitting a key, donut dumps core. Here's a stack backtrace:

The specific problem seems to be this:

#1  Buffer::getSample (this=0x55b0f3a1be80, sample_position=3000)
    at /storage/main/work/local-src/donut/src/Buffer.cpp:43
43	    return this->operator[](sample_position % size);
(gdb) print sample_position
$2 = 3000
(gdb) print size
$3 = 0

I'm running on Debian Linux current under Pipewire-jack, which may be relevant.

Let me know if I can give more helpful info.
