So, I'm using the MC8 to send PC messages to my nemesis delay and ventris reverb pedals, but there is an issue. Many times, The pedal does nothing and ignores the pc message. So I have to press the Preset switch on my MC8 multiple times to in order for the ventris/nemesis to atually work. Sometimes it works on the first press, other times it takes two or three attempts. This only happens to my source audio pedals for some reason. Am I doing something wrong? I have a gig coming up, so I need this to work.
