Arduino OPL Bus Sniffer – Part 2

Having now made myself a Arduino OPL Bus Sniffer I've put it to some use grabbing the voice data from the YM2413 based Yamaha PSS-170 keyboard. https://youtu.be/evERlSJY7zY Warning! I strongly recommend using old or second hand equipment for your experiments. I am not responsible for any damage to expensive instruments! These are the key Arduino tutorials … Continue reading Arduino OPL Bus Sniffer – Part 2 →

Arduino OPL Bus Sniffer

This is a slightly off-track application. I want to be able to probe a YM2413 chip "in situ" - i.e. installed in a keyboard, so I thought it might be interesting to develop an Arduino application that can monitor the data signals and pull out the data being sent to the chip. Warning! I strongly … Continue reading Arduino OPL Bus Sniffer →

Arduino OPL FM Drum Machine

I've finally returned to having a look at my Arduino OPL FM Synth. This time I'm taking a look at the drum channels. https://youtu.be/IBDu9h4716U Warning! I strongly recommend using old or second hand equipment for your experiments. I am not responsible for any damage to expensive instruments! These are the key Arduino tutorials for the main … Continue reading Arduino OPL FM Drum Machine →

Arduino OPL FM Synth – Part 2

Despite saying last time that I looked at the YM2413, I didn't need to build a protoboard version of the YM2413 "shield", I've had an idea for something that would really benefit from one, so here it is. I've built it onto one of my Arduino MIDI Proto Shields. Warning! I strongly recommend using old or … Continue reading Arduino OPL FM Synth – Part 2 →

Arduino OPL FM Synth

Someone recently asked me about a 2413 synth chip emulation library they'd found for the ESP32 and I'm very interested in taking a look. But I've not done any ESP32 projects so far, so that will have to wait for a bit (come back in a few weeks maybe). But that reminded me that I … Continue reading Arduino OPL FM Synth →
