I'm having a hard time with the mix now and on play back, my drum kit was way too quiet and my keyboards and guitar were way too loud.
Because your guitar part is such an amazing track the remix is a good option for your fans! The best way to fix the volume is to download the zip tracks from server and remix each individual instrument in a sound editor.
I hope you can change the volume in your remix for each instrument, I often use Audacity for that but I am just an amateur.
Of course your idea to check the right volume during jams is a must do so we have to fix our volumes if possible in a sound test at the beginiing of the jam if a musician is ready to listen to the whole band. Otherwise I hear my keys louder as you notticed in playback than dururing jams when it looks ok…
