This is an improvisation on Zynaddsub-FX. Later it came out Vangelis has a soundtrack piece called "Missing" which is similar. Oh well, great minds... And all that His is a full piece with strings though, not a meditational motif.
Sampled electric clean guitar processed in Reason 3. Another couple guitar instruments with a similar Reason 3 stack play in Game06.mid. The other instrument is Microtrance.
The "not-a-Moog" synth improvisation. Almost all the VST effects here are free, the synthesiser is ASynth. The overall setup is similar to what Tony Iommi and Justin K. Broadrick use on their guitars (source->chorus->reverb->delay), with a lowpass filter replacing a guitar cabinet/speaker (guitar speakers usually go only up to 5-6 KHz).
