      1. “welp” – it’s not actually that simple. This output signal is basically just a DC-offset pulse.

        If your device’s audio outputs aren’t DC coupled, which many audio outputs *aren’t,* this may not work as-expected.

        Given that this is just a ‘trigger pulse,’ you’re more likely to have at least *some* success even with a non-DC-coupled output, but the pulse may end up being significantly shorter than expected, and won’t stay at the same voltage, due to the capacative effect of the non-DC-coupled outputs. (You’ll basically get a falling pulse rather than a ‘square’ pulse).

        Additionally, a more complex set of features you can do with a DC-coupled devices is to actually generate the voltage outputs that you can use for pitch.

        All of this being said, there *are* ways of making special cables that will let you use audio-frequencies as control voltages via some simple electrical magic. This is how some of the specialized “Silent Way” adapters work, and also how their “AC-coupled interface cable” works – seen here: http://www.expert-sleepers.co.uk/siwaacencoder.html

        Hopefully this will help clarify why this isn’t as simple as “Does it have audio outputs?”

        1. ” Hopefully this will help clarify why this isn’t as simple as “Does it have audio outputs?” ”

          no, it didn’t clarify anything as you didn’t address the mpc at all. in fact, sorta made this topic more muddy.

          mpc’s have DC coupled outputs. no need for interface, or special cables, or a module. (or magic)

          this sorta is that simple, if the outputs (of what ever you are using) are dc coupled, it will work. if they are not, it won’t work accurately.

          basically, “are the mpc2500 outputs dc coupled?” is what i think he was thinking
