I try to make backing tracks with mu Juno Stage, convert them to MP3, load to song player and then play along in my gigs. The problem is - in patch mode and performance mode patches sound very different. Yes, I know why and yes, I hate Roland for doing this

I think there is no easy way to make backing track with Juno Stage because - tonality of the patches is very different. I have not found a single good electric bass guitar sound for example. Comapared to other sounds they all have way too much bass.
I use SRX-01 sound expansion, and all the drumpatches in this card are much quieter than the built in pathes. Also the patches in SRX-01 are not in traditional GM setup !
So I decided to record track by trakc using Juno Stage in Patch mode ! I record all tracks to audio and mix them in Logic studio. I found this to be better way to do this. Still the bass guitar sounds are a headache for me. Has anyone made good electric bass guitar user sounds ? The ones in Juno stage are boomy and over-pushed low freqs. Does the Srx-07 help out ? Are bass sounds in it better ?
