Thanks for your comments! I used a Yamaha CS6x synth for all the sounds.

For 'Weightless' The drums are commercial loops I bought ages ago. I used Steinberg's Halion for all the drums and it was recorded in Cubase SX.

'Time Wished Away' was recorded in XGWorks with a Soundblaster, using the CS6x for all sounds including drums.
