No. This is the way the MIDI spec works. Velocity is part of the MIDI
note-on message.
What you want to send is key aftertouch messages (also called polyphonic
aftertouch or key pressure). Or channel aftertouch, if your synth doesn't
do anything with poly aftertouch.

I don't know if general MIDI has assigned controllers for attack and
decay, but I really don't think it would.
But maybe your synth has controllers or sys-ex messages assigned for this.
Look in the manual.
