I collected as many Yamaha DX7 patch files as I could and deduplicated each voice within each patch file. There were 59,907 SYSEX files, most of which contained a bank of 32 voices each, for a total of 1,853,728 voice sounds. After hashing the non-name content of the voice (the actual parameters of the sound), I found 31,380 unique voices made by musicians over the years for the DX7.
Make a robot friend with Adafruit’s CRICKIT – A Creative Robotics & Interactive Construction Kit. It’s an add-on to our popular Circuit Playground Express, FEATHER and other platforms to make and program robots with CircuitPython, MakeCode, and Arduino. Start controlling motors, servos, solenoids. You also get signal pins, capacitive touch sensors, a NeoPixel driver and amplified speaker output. It complements & extends your boards so you can still use all the goodies on the microcontroller, now you have a robotics playground as well.
