Hi Adam

It sounds like the CPU fuses that set clock speed have become corrupted during the update. This never happens and may point to a poor power supply in your 106. This board will need reprogramming via the ISP port and probably should be done here.

The Kiwi106 board is sensitive to bad power and it seems that a number of 106s are showing signs of the 7805 reg dropping the output voltage over time. It could be the brand or batch of these Roland used as it is not common fault with these regulators. I would recommand that if you have a 106 that you replace this part. It is a simple job and the part is readily available. Any TO220 5v Reg will work. An example would be https://www.digikey.com/product-detail/en/fairchild-on-semiconductor/LM7805CT/LM7805CT-ND/458698

Contact me directly so we can sort this out.

Hi. Updated the Boot and Prog from this package and I'm having some trouble. My 106 isn't running right, seems to be slow... the patch numbers light one at a time, then the other panel lights for the current patch light alternating to that. Sound is slow and intermittent. I tried updating again, and even rolling back to previous versions but it still runs like this after the firmware updates. Also tried with 3 diff MIDI interfaces just to be sure, but same problem. I never had trouble previously updating manually like this through SysEx Librarian.

Any ideas what's going on. Synth is not usable currently, hope it's ok. Thanks.
