  • Launchpad fixed

    Since I had a few likes after my post on Novation Launchpad Malfunction in this forum group, I suspect there might be a few folks with the same problem: When you press any pad in columns 3, 6, or 9 MIDI messages from the adjacent leftmost columns are sent resulting in three messages. I diagnosed faulty diodes in the column of diodes from D6 (top) to D77 (bottom). At first I replaced only the first three. The problem appeared to go away but returned intermittently. So I replaced the rest of the nine diodes in the same column. The fix looks good. I used LL4148 diodes (cheaper than dirt). If you haven't repaired surface mount boards before, please look at a few Utube videos on SMD replacement so you don't damage the circuit board.
