Amazing work. I briefly explored trying to RE a more modern piece of hardware, the Tascam Portastudio DP-24SD, in order to try to fix some well-known bugs and limitations. Your article inspired me to maybe give it another go.

Previously, I managed to decode a firmware update file for the unit, but quickly found out that it uses a special-purpose DSP chip, and I wasn't able to easily find public documentation for its instruction set. So I gave up. Do you have a gut feeling on if REing and hacking this firmware could be done by a dedicated amateur, or is this probably more like professional-level work and I should find something better to do?
