No Difference Between Goa Trance and Psytrance? in General Psytrance Posted September 6 Goa to me is melodic, psy trance seems....rather more... harmonically manipulated synth sound effects... rather than melody, maybe a few Phrygian note phrases. Psy trance for me is characterized by the ever used and relied on kick and bass, I still really like it. The bass is saw wave repetitive acid, very highly refined with emphasis on bass and mid range. I realized this is essentially an acid sound one morning when I heard a track with the normal KbBB bass was performed by something that sounded very much like a TB-303, the tent I passed I had to go in and dance it was great ! The tonality was superb although less controlled timing than a simple bass sample or a modern soft synth with phase reset/retrig. (has a more wild, running away feel to it) The 303 style bass has a more "wet" liquiddy sound to its filter sweep. This track gets close to the sound.. in fact it may possibly have been this track, it was 6 years ago so I cannot recall exactly.
