MOTM

so i am wondering....

besides a synth's kb or midi-to-cv unit, what else can produce a gate &
trigger signal that i can use to drive my motm-800?

my controlling keyboard, a jupiter 8, has only CV and gate outs. can a
trigger signal be 'extracted' from the gate signal (they both start off the
same (with a voltage 'pulse'), right?) so that i can use the gate *and*
trigger with my motm-800 (gaining full ADSR functionality)?

is there a way, using currently available motm modules, to take in an audio
signal and output a voltage based on the audio signal's amplitude? (like an
envelope follower)

thanks,
mark
