Enjoy the music from IX and the few from other games in the DQ series. 
All the music for IX has been taken from the Symphonic Suite for that game. Also as of 27/09/21 the synthesised soundtrack from IX has been getting implemented into Project IX (Version not currently released) for those that want a more authentic Dragon Quest IX music experience to enable this just switch from Orchestral to Synthesised while implementation of the 4 Heroes of light soundtrack will now be used for Tickington.

Version 5.0 patch - just a small one this it finally brings a fix to Swirling Desire (boss music) for whatever reason not existing since 2.0 in PIX ive also replaced the Miniboss music so its no longer the standard battle theme.

Patch 5.3 - Just a minor 1 this, brings about changes to a Symphonic track for towns like Puerto Valor during night regardless of the option it would only play the symphonic version now though the game will play the synthetic track if you have the synthetic option selected, this update also brings out minor improvements to the looping of the Orchestral Battle Track as well as bringing in some more Synthesized tracks to cover some of the missing bits like the Story So Far, File Selection Screen and The Overture will all now have IX synthetic versions instead of just defaulting to the XI synthetic tracks.

Patch 5.7 - Again just another minor 1 this time fixing loop points for 2 of the orchestral town tracks and creating a better loop point for the orchestral battle track.

Version 6.0 patch - Still in development - brings huge improvements to the looping and volume of a lot of tracks also I've started to roll out the newly mastered stuff too which means the size of this mod will start to jump considerably due to audio quality improvements across the board, version 7.0 is where I will start to roll out more variation in the soundtrack instead of just replacing songs. (oh and the standalone version will get its final update b4 its discontinued), If you prefer the synthetic stuff then not to worry the mastering process for that is almost done while not perfect it will eliminate a lot of the distortion, loop points ofc for that will be perfected into the future.

Final Fantasy The 4 Heroes of Light ost: I've started rolling this out in Tickington but there's a few uses of it outside Tickington most notably the boss theme for the 1st phase of Mordegon in act 2 (maybe the ruins theme too so cobblestone destroyed cant remember)
