I've been thinking of starting a thread for "Tips" on using the Pro 3.
Things you've noticed that maybe weren't obvious.
==============
-- Set start-up program --
I was going to ask how to set the program that shows when you start up the unit.
Well... RTFM (again). [Read The F. Manual

]
- Press the Global button twice while you are on the program you want!
==============
-- Turning Cutoff down further than the knob goes. --
The Cutoff value can be raised (or lowered?) so far (by Envs/LFOs, etc.) as to limit the Cutoff dial's ability to turn it further/all the way down.
You can use the DC (constant) control in the Mod Matrix to offset/lower the Cutoff knob's 'center'/lowest setting.
DC >> -# >> Cutoff
==============
-- Use the Mod Matrix for BP/Band Pass control --
The Band Pass value/button can be a destination in the Mod Matrix! ("SV Norm-BP")
(That makes 3 variable filter controls for the SV filter!)
I leave the button off.
==============
I love using one of the Aux Envelopes for a Noise envelope!
Just set it to control the "Noise" level destination.
(This can also be done in the Mod Matrix of course.)
Env Aux 1 >> +64 >> Noise
(I wish that destination was called "Noise Lvl". But that's a minor thing.)
==============
You can check all of the Fixed Mods quickly at the bottom of the list in the Mod Matrix (Modulation) menu.
(The 3 LOFs and The 2 Aux Envs.)
==============
P.S. Forum mods: the "Pro 3 User Guide" link seems to be broken in the forum post?
