"Remember the old Simmons drums and the more recent ddrum systems that carried that magic ZIF (zero insertation force) sockets?
Sounds replaceable by just swapping chips in a socket without tools?
Those days are back.
The 4HP DDM module does that and more.
It allows you to swap the sound chip with just your fingers, even during a live performance.
But it gives you more than the old EPROMs did.
The chip does not only contain sample data but also the entire DSP algorithm programmed.
It features 4 analog/digital CV inputs and a parameter knob.
1 mono analog output.
And you can program it yourself because it’s an ATtiny 44/84.
Yes, it works in the Arduino IDE envoirement.
This is really a tribute to the old technology with some 21’st century tech in it.
Enjoy programming your own modules and swapping chips."
