seq3.4c strange track1 button behavior

MIDIbox SEQ

Hello. I’ve noticed a strange track buttons behaviour. When I click TRACK2 buttton just after a power-up, the track changes, but when I change back to TRACK1 and again TRACK2, buttons behavior changes and now I can only “checkbox” tracks, not change it, and I cannot “uncheck” track 1. The result is that I havee track1 checked all the time, and I can add any combination of other tracks in group.

Suprisingly, only TRACK1 button behaves strange. The rest works just as described in manual (click to select, hold to select multiple), so when after a power-up I select any other track and NOT select track 1, everything is fine…

Is it a kind of bug, or is it something wrong with my hardware? I had seq3.4a firmware earlier, with the same effect…

Sounds like a faulty switch or wiring to me… Have you tried swapping the switch out with a spare?

It haven’t sound like this to me, but it was wiring (short between two legs of switch). I was misled by the fact that first click after power-up was ok. Thanks very much. Sometimes simple things are most hard to understand :wink:

Yeh, that occurred to me too! Strange machines… :stuck_out_tongue:

Glad it’s working!
