I've noticed when using Cynthcart with the release set to long, that when you release a chord, it sounds sort of cut off and weird (at least on my Cynthcart). But by using this trick you can let those chords ring out!
Say you play a chord. Normally it will sustain as long as you hold the keys down but as soon as you release the chord, it sounds weird... It sort of plays the highest note again...hard to describe. But if you hold down SHIFT after you play the chord, and then let go of the SHIFT button, it will sound fine... The notes you played continue to ring and fade away appropriately.
It has to be the SHIFT button on the left side of the keyboard, not the one on the right.
It also acts as a sort of HOLD feature... It will hold the note/notes that you played until you release it.
I know this sounds sort of strange, and I'm not sure if everyone's Cynthcart behaves this way, or just mine. If anyone wants to verify this behavior on their Cynthcart, be my guest!
