oscilloscope and tuner will be included in ESP32 module as basic firmware
Not a module idea but a kit idea could sell a kit for a simple east coast synth another for west coast synth and possibly a simple monophonic analogue fm style synth kit. I think this format of modular could be great for demonstration in the class room explaining how a Synthesizer and the various styles of Synthesizer function. Another idea might be to sell multiple of these kits in education bundles so people in the classroom can get a hands on experience rather than it just being explained to them.
This one I canāt see many people having a use for apart from my haha. An Arduinoboy/teensyboy to cv. My thought for this one is lsdj for the gameboy actually has a version for midi out combined with this module the system would have an affordable and versatile tracker (if you have a gameboy that is haha).
The ESP32 module probably covers that already (MIDI to CV/gate conversion).
Do we know how many outputs there are going to be on the esp-32 for midi yet? I was thinking a dedicated module with a built-in link port for the gb but definitely think id be the only one to use this moduleš¤£ haha
