Hi there,
long time Samplitude user here! I upgraded to the Suite X7 version and immediately noticed that the expression curve controller that was introduced in X6 is completely missing. For me, this was THE reason why I upgraded to X6 back then, as I spend 90% of my time in the MIDI editor. You can no longer scale and move curves, which is a substantial downgrade from the MIDI editor functions present in X6.
