I have a Yamaha DTX Multi-12 drum pad. It's great, but its fatal design flaw is it doesn't support samples over ~5 sec/ ~100 KB. I would love to be able to import pop-song-length CD-quality samples (+5 min. @ 192 Kbps).

I don't really know where to start with this. My first guess: Find a compatible 16GB+ SSD 2.5" hard drive, attach it to the motherboard, then tweak the software so it can recognize and accept importing larger file sizes/longer sample lengths. How you actually do all that is beyond me.

Anyone have any insight into a fairly advanced project like this? Thanks!

I don't think the software can be 'tweaked' since it's built in some flash/EEPROM and cannot be edited.

The most easiest way is probably to use an external sampler, assuming your Yamaha DTX has MIDI output. Modern samplers (or even by using a laptop with MIDI interface) can give very long samples.

But of course this would 'spoil' the project.

  • \$\begingroup\$ Getting an external sampler is probably the path of least resistance. I was hoping to pimp out the DTX so it behaved more like its main competitor, the Roland SPD-SX, which can process long samples like a champ. \$\endgroup\$

  • \$\begingroup\$ I'm afraid that changing firmware is almost impossible to do. Since you would need not only the specs of all components, but also find a way to reprogram the flash (and creating ALL software yourself). Building a new one yourself might be easier. \$\endgroup\$ Sep 22 '17 at 19:36
