THORN synth crashes on render

Mac 10.12.6 Reaper 5.70/64 The past couple of days I've been using the THORN synth to generate a bunch of sounds. It works fine, until after a render, when Reaper crashes more than half the time. The file will finish rendering, and its usually when I go to close the finished render window that Reaper crashes. This is happening a LOT, and I hope this crash report can shed some light. I'll post others as I'm still using it today and I know there will be more crashes. THORN can be grabbed here: Thread 57 Crashed:: com.apple.audio.IOThread.client 0 com.dmitrysches.thorn 0x0000000158cb7a87 SpringReverb::Process(float*, float*, int) + 1031 1 com.dmitrysches.thorn 0x0000000158cb0573 CEffects::Process(float*, float*, int) + 115 2 com.dmitrysches.thorn 0x0000000158d059c2 Processor::process(float*, float*, int) + 546 3 com.dmitrysches.thorn 0x0000000158c62dac JuceProcessorWrapper::processBlock(juce::AudioBuff er<float>&, juce::MidiBuffer&) + 1548 4 com.dmitrysches.thorn 0x0000000158c4241a void juce::JuceVST3Component::processAudio<float>(Stein berg::Vst::ProcessData&, juce::Array<float*, juce::DummyCriticalSection, 0>&) + 1642 5 com.dmitrysches.thorn 0x0000000158c3dfeb juce::JuceVST3Component::process(Steinberg::Vst::P rocessData&) + 395 6 com.cockos.reaper 0x00000001007c2e63 VST3_ProcessReplacing(AEffect*, float**, float**, int) + 3443 7 com.cockos.reaper 0x000000010039c67e VST_HostedPlugin::ProcessSamples(int, double*, int, int, int, double, midi_List*, bool*, double, double, double, bool) + 5934 8 com.cockos.reaper 0x00000001003c2e77 FxDsp::processSamples(int, double*, int, int, int, double*, midi_List*, double, bool, double) + 5063 9 com.cockos.reaper 0x00000001003deec4 FxChain::ProcessSamples(int, double*, int, int, int, int, double, midi_List*, double, bool) + 452 10 com.cockos.reaper 0x00000001000f2eb4 MediaTrack::RenderSamples_nocache(double, long long, double*, int, int, double, MediaTrack**, int, int*, bool, int, int, bool*) + 14356 11 com.cockos.reaper 0x00000001000fa6c5 MediaTrack::RenderSamples(double, long long, int, Track_RS_Output*, int, double, MediaTrack**, int, midi_List*, int, int, int, int, int, MediaTrack::Track_SendRec*, bool*) + 2725 12 com.cockos.reaper 0x00000001000f1654 MediaTrack::RenderSamples_nocache(double, long long, double*, int, int, double, MediaTrack**, int, int*, bool, int, int, bool*) + 8116 13 com.cockos.reaper 0x000000010018edc0 process_sample_block(ReaProject*, int, int, int, int) + 240 14 com.cockos.reaper 0x000000010018d103 ProcessProject(ReaProject*, int, int) + 5811 15 com.cockos.reaper 0x000000010018b86d audiostream_onsamples(double**, int, double**, int, int, int) + 5453 16 com.cockos.reaper 0x00000001001e93b5 caIOproc(unsigned int, AudioTimeStamp const*, AudioBufferList const*, AudioTimeStamp const*, AudioBufferList*, AudioTimeStamp const*, void*) + 597 17 com.apple.audio.CoreAudio 0x00007fffc45408ce HALC_ProxyIOContext::IOWorkLoop() + 5290 18 com.apple.audio.CoreAudio 0x00007fffc453f264 HALC_ProxyIOContext::IOThreadEntry(void*) + 128 19 com.apple.audio.CoreAudio 0x00007fffc453efa3 HALB_IOThread::Entry(void*) + 75 20 libsystem_pthread.dylib 0x00007fffda93b93b _pthread_body + 180 21 libsystem_pthread.dylib 0x00007fffda93b887 _pthread_start + 286 22 libsystem_pthread.dylib 0x00007fffda93b08d thread_start + 13

- You are using the latest version of Thorn ? - Does the crashing occur with both AU and VST version ? - Can you maybe post a screenshot of your Render settings ? - What are your audio device buffer settings and which audio device you are using ? Warm Regards.

This is the last one I'll probably post. There's got to be a common thing happening in here. Its been happening all day.

What happens if you choose 48k as sample rate in the Render window ? And also: If you open "Project Settings; and then open the tab "Project settings", do you have the setting "Project sample rate" enabled or disabled ?
