| br>Hi guys--
So I am setting up the unipulse to work with my Hammond Auto Vari 64. I have a 25V supply feeding the voice board and the UniPulse. They both seem to work, but I'm having a strange issue-- the sounds fade in and out as they are struck, and then stop.
So, using the "test" button on the configurator, the first hit works, then the next 4 or 5 hits are lower in volume, and then nothing. When I plug it back in to the original setup -- no tubbutec, afro-cuban-buttons version-- it works okay.
I am using the open rect, 14V, etc. as specified in the page dedicated to this machine on the Tubbutec site.
We are tapping the "hi freq out" and "lo freq out" on the voice card to listen to.
Attached is the pertinent schematic and also a pic of the setup as it is, which is a crappy pic, but all i have at the moment.
Any ideas why this might be happening?
