I recorded ten songs written/sung by Harry Nilsson.
Used Ardour on Linux. Oft used plugins include Linuxsampler and ZynAddSubFX, EQ10Q, FC70, Luftikus, IR, Calf Vintage Delay, GxDigitalDelay, some of the Guitarix fuzz pedal and amp simulators, Barry’s Satan Maximizer.
I’ve finally relented and started using a few bits of Windows software again after ten years away - in this case, for vocal correction (I’m no Harry Nilsson) and ‘mastering’ (In quotes because I did it, but I can’t claim I had the ears or objectivity to master it right.)
