Hi Larry ,
As far as i know , you have to choose between each other , it doesn't work together . That said and i don't really know why , may be i didn't understand everything in this pedal , it seems that when the flanger is on , you still can hear a chorus sound...i might be wrong on this so the best is you try yourself , i'm sure u won't be dissapointed...of course , it's just a matter of taste :-)
Jbybj ,, i didn't try the synth pedal but it interests me indeed ! Did u find new sounds thru the Markbass software ?
