Instead of placing Voices in Master Mode, place your favorite Voices in PARTS of a SONG/PATTERN MIXING program...
for example:
PART 1 for piano
PART 2 for strings
PART 3 for flute
etc.,

Now when you need to switch between sounds use the numbered Track Select buttons... there will be no hesitation or interruption between sounds... In fact you can press [2] play the strings, hold a chord with the Sustain pedal, switch to flute by touching [3] while still holding the strings with the Sustain pedal you can be riffing on the flute.

Switching Parts in a Song Mixing or Pattern Mixing Program by moving Track to Track leaves no hiccups or interruption in your sound. The reason being the MIXING setup lets you recall all processors and EQs at once, so switching between Parts is “sonically invisible”... as opposed to when you were switching Voice to Voice using Master Mode.

Try placing the sounds you need to get to rapidly in adjacent PARTS of a MIXING.
When you have a ton of time between switching instruments, then you can use the standard methods to switch between programs. Please realize you don’t always need seamless transitions, but when you do use a MIXING program and your TRACK buttons to switch instruments.

Really useful, thanks
