Reaper not exporting sound for tracks with Cabbage plugin effect


I made a simple convolution plugin effect with pconvolve and using the button widget to get the path for an audio file to serve as the impulse and whenever I try to render a track that uses this plugin in Reaper, the particular track affected by the plugin is just silent.

I tested the same plugin in Cubase and it exports alright. I also have no problem exporting audio from two other synths I’m building with Cabbage in Reaper, just this one convolution effect.

I can freeze the track in Reaper and the plugin prints fine, I just can’t render an export with the plugin working. Does anyone know why might that be?

Thanks in advance!

Can you confirm that the problems occurs with the Cabbage convolution example? If so I have something to test with. Alternatively, can you post your .csd file so I can test with that?

Just tried it out with the McCurdy’s Convolution Reverb Example and the problem still occurs in Reaper.

Here’s my .csd:

Edit: also after exporting, the plugins acts like there isn’t an impulse response loaded, muting all audio coming from the affected track (but still shows the loaded waveform on the display)

Thanks, I’ll check it out when I get a moment. Most likely tomorrow evening :wink:

I’ve been using the plugin more and I’ve been noticing some inconsistent behaviour with regards to file loading. When reopening a session, some instances of the plugin seem to “remember” the file I loaded previously while other instances start blank. I noticed this on both Cubase and Reaper.

I’m sorry I haven’t had a chance to look into this yet. I’ll definitely have more time towards the second half of the week. Watch this space…

No worries at all! Take your time

I’m just trying this out here, and it seems to work fine for me. I can load an impulse. Tweak the parameters, and then render to disk. The resulting audio file is what I hear when I process the sounds in Reaper.

I’m using 2.5.0.

I’m going to check the sessions saving issue now :+1:

[edit] my impulse responses are also saving with the session. I wonder is there anything unique to how you are saving them or recalling them. I thought for a moment it might have to do with the plugin editor window being closed when saving is taking place, but I tested that too, and it still loaded Ok. :thinking:
