"Nova's Elixir" [3.5 MB .mp3]
Original title: "Softsynth Interaction." Have been learning the Tracktion digital audio workstation, which has a Linux version. Looping MIDI works there, where it's still buggy on Ardour. Tracktion-on-Linux is incredibly stable as long as you use their house plugins. Instead of an unfortunate limitation, am trying to think of it as fact of life and treat Tracktion as a self-contained instrument sitting on the PC -- like a virtual Octatrack -- that can do some interesting things.
Have not yet gone full-on Tracktion; most of this tune is made in Ardour with a combination of Ardour- and Tracktion-made loops.
The basic beat was done in Ardour with the LSP Plugins sampler instrument. The first two synth voices are also Ardour-made, employing (i) the Calf Monosynth and Harrison reverb running inside the Carla plugin host (which works fine except for the audible pop at the loop point -- the developer hasn't coded for that yet and it only affects monitoring, not the exported audio loop, but it's still annoying) and (ii) Loomer Aspect.
The other synth voices and beats are all sequenced in Tracktion using non-Tracktion plugins, then imported back into Ardour for a final mix. The synths are Loomer Aspect (a different patch), Helm and ZynAddSubFX. I got these working at about the 90% level -- I couldn't save presets or they might crash but it was enough to get some audio saved.
The challenge here was mastering. That beat has a very heavy bass kick that interacts badly with other tracks when you boost the gain for a "CD mix." To get it up to the same volume level as my other tracks without obvious distortion, I had to use the PSP Vintage Warmer on (sigh) Windows, which I was hoping to move away from. None of the Linux limiters I tried (including Tracktion's) could handle the job. If I was a pro mixing engineer I would fix this in the mix but it's beyond my skill set ATM. [/linux diary]
