Hi all

I am prepared to make myself seem like an amateur. I have  been using
a modular synth for about a year now and have just decided to MIDI/CV
it up to actually play NOTES of all things!

What has me totally baffled is this.  When I am pressing down a key on
the midi keyboard i get the note then when i take my finger off the
key there is a few octaves above playing until i again press another
key. I cant work out what is going on, it must be something so simple
I have overlooked it.

here is my complete set up for this .

Frostwave MC1 midi CV - MIDI out to MIDI IN synth, Frostwave CVA to
Plan B Complex VCO 1v/o, Frostwave Gate to Doepfer A143-2 Quad ADSR
gate in, gate out to Serge Universal Audio Processor VC1+2 so that 
the ADSR shape is going into the VC1+2.

I would live to solve this issue

cheers
