I bought a used Roland TD-4KP with added mesh pads and cymbals.
The things is that the TD4 module that comes with it doesn't have the aux input for a 3rd cymbal, and some pads, like the toms, have a single trigger.
Is there some device that just takes the trigger input from stereo audio jacks, and sends the MIDI notes through USB or bluetooth and that's it? No sound banks, no nothing.
I only need one specific function of electronic drums, which is turning my trigger hits into midi notes to output to my PC and use VSTs.
The problem with most drum modules is that they don't have enough trigger inputs for the pads and cymbals I want to use, and the ones that do are usually high-end and thus very expensive.
I'm wondering if there is such a thing.
