    <p>Sorry to be coming in late on this one but a good friend of mine
      built an entire poly-synth around this readily-available ARM
      M7-based sample playback module:

    <p>His synth is pretty neat:

        <div>Very interesting replies, thanks again guys!!</div>
        <div><br>
        </div>
        <div>I agree there are several other options to achieve what the
          SAM chips can do, it just seemed like a nice convenient option
          with fast, possibly big memory. And i liked the thought of
          re-using somewhat old chips/technology in a new DIY context.<br>
        </div>
        <div><br>
        </div>
        <div>I would think at least for my purposes an ESP32 or teensy
          solution would be the easiest alternative, and they should be
          plenty fast enough for the rather simple sampling engine that
          i need. While the SAM chips basically supply a kind of full
          fledged Wavetable-Synth-Engine, i really only want simple
          sample playback/repitching. I don't really have a clue about
          RAM speeds/platforms/buses etc but to simply play back lets
          say up to 8 simultaneous voices, the above mentioned ESP32
          base WVR board with 8GB onboard flash memory should be fast
          enough. I managed to do the same even on a rather outdated <a
            href="http://axoloti.com" moz-do-not-send="true">axoloti.com</a>
          board, streaming from SD-Card...</div>
        <div><br>
        </div>
        <div>But yeah, it would be great if someone could come up with a
          faster low level implementation on an ARM/teensy based board
          with plenty of fast RAM as Brian suggested. I agree that an
          FPGA is not the right solution for this application, , as
          interesting as the tech is. Especially for a simple-minded MCU
          person as I am. <br>
        </div>
        <div><br>
        </div>
        <div>FWIW, i also finally received a response from DREAM
          themselves, where they kindly pointed me towards serdashop as
          well, and confirming that supplying end-customers or DIY
          people is beyond their workload capacities ATM.</div>
        <div><br>
        </div>
        <div>Oh and also this mod-wiggler user called ixtern built a
          prototype for a Dreamblaster-based standalone instrument as
          well, i am talking to him as well:</div>
