Hi There.
I have built a Seq v4 Lite with the LPC17 core. The core seemes fine. I get past all the midi tests, the led on the expresso is flashing three times when booting and everything seemes right in Mios Studio. The Sd-Card is working and has been "formated" by the core. However the panel is not working at all. When I fired it up the first time there was no light at all :( When I tried the pushbuttons I got feedback in Mios Studio. If I remember correctly it told me exactly wich button I pressed, but after a while it reported buttons only occationally and randomly. Now it does not give any feedback at all.
I have changed all four of the cables between the panel and the core, I have tested all the components on the panel and found nothing wrong (that I can spot with my limited knowledge), and I have preformed the midi loopback tests with expected results.
Any thoughts about this would be very appreciated.
Thanks!
Kolbjørn
