<!-- SC_OFF --><div class="md"><p>So, having learnt the ultranova is based on the NXP DSP56300 series DSP, ive decided it might be worth trying to get some custom wavetables loaded into the firmware, especially as you can just dump the binary as sysex. I'd like to assume they are simply lookup tables, stored somewhere in the firmware, in which case they should start at a specific offset and are likely 32bit waveforms, I could of course be wrong. The specific DSP chip, the DSPB56724AG has a decent amount of RAM, much more than a single wavetable could take up.</p> <p>I may well look into disassembling the firmware in ghidra or IDA if I get time, however I'd be reluctant to send an OS assembled without proper knowledge of the underlying hardware to the synth for fear of bricking it, so modifying the exact memory locations containing the wavetable data is a safer option.</p> <p>Would be helpful of there is anyone from novation here who might be willing to provide some information that could help.</p> </div><!-- SC_ON --> submitted by <a href="https://www.reddit.com/user/Lewinator56"> /u/Lewinator56 </a> <br/> <span><a href="https://www.reddit.com/r/synthesizers/comments/xjpcr3/anyone_know_how_the_ultranova_stores_its/">[link]</a></span> <span><a href="https://www.reddit.com/r/synthesizers/comments/xjpcr3/anyone_know_how_the_ultranova_stores_its/">[comments]</a></span>
