This is an updated version of https://lmms.io/lsp/?action=show&file=13252

In the earlier version, when exporting this track, the resulting audio file has a lot of static/clicks in the first 30 seconds or so. After receiving some suggestions from GDD71 and Speware (thanks, guys!), I made some changes (details below), and now the exported track comes out clean. If you experience the same issues, you might try some of the things I mention below.

Changes:
Preface: The clicks were primarily being caused by a lack of CPU resources. When exporting, the CPU bar in LMMS was pegging out in the red for most of the track. The first thing I tried was to export instrument tracks individually, then compile them into a single WAV file using third-party software. But that proved ineffective. So, my next angle of attack was to scale down anything that would max out the CPU.

1. I removed any unneeded effects from both the mixer and individual instruments. From the FX-Mixer, I removed the Dyson Compressor, the Spectrum Analyzer and the Equalizer. In particular, I think the Dyson Compressor is the biggest offender.
2. As for instruments, I replaced the C* Plate2x2 effect with the Calf Reverb LADSPA (and in one instance the TAP Reverberator) on any instrument that didn't require the Plate2x2 blending. So, if all I wanted was reverb/echo, I changed the effect. However, after applying change #3, I reverted back to the Plate2x2 as I preferred its sound.
3. The Padd 3O instrument had heavy echo and reverb, and as such it used the majority of CPU resources. When the first two changes were not enough, it was time to tackle this one. Recreating its resonance and sound was a challenge, but I managed it using a combination of soundfonts and staccato notes with reverb, rather than relying on the 3O with effects. Check out the project file for details on which soundfonts I used. The result uses a fraction of the CPU resources the 3O did.

NOTE: Since I deleted the EQ from the mixer, I had to apply EQ settings in post, so the raw file is bass-heavy. I'm sure I could add the EQ effect back to the mixer and be fine in terms of CPU usage during export, but I skipped that step since I already had my track completed.
