Hi, has anyone created a "converter" to connect the MIDI keys to the Audiowave cartridge? I have seen the opposite solution (Yamaha YK-XX keyboard can be connected to the MIDI components). So I ask not to start working on something that someone has already done... I want connect cheap MIDI keyboard to Audiowave cartridge.

I don't see that happen. There's no midi inside that cartridge.

Why not get a Yamaha YK keyboard?

Maybe a bit more expensive than a cheap MIDI keyboard but at least they will work straight away.

I have little space at home and I can't have x different kinds of keys... MIDI keys I already have. I know the cartridge doesn't have a MIDI input, but it probably won't be a problem to use a Arduino to create a "bridge" between cartridge and MIDI keys. That's why I asked if anyone had encountered this solution before I tried to make it.

I have not read about such a project on the forum.

I wonder if latency could become an issue (but I am no musician)…

Midi is a simple serial interface. So I think it's simple to convert it for people who know protocols and a bit of electronics. Transfert speed is 31,25 Kbps. I think that's enough to send the status of a few keys. Modern Midi devices use USB instead of DIN connector.

I didn’t say it would be difficult. But any delay added to the transfer of the signal by pressing the key until output of sound can possibly be a problem. Well it was more a question even…

I didn't say you said it. Wink

I think scoring a Philips Music Module would save you a lot of hassle.

Philips Music Module look nice but I have a new Audiowave module... How it will be with latency will be seen. There will probably be a small one and it will be seen during the test what it will be like (maybe it will not be so critical). Basically, it will be a converter from a serial port (MIDI) to a parallel (YK-XX is just a matrix of switches). I'll let you know if such a converter will be usable. Probably just Arduino and a few resistors. I've been playing programming for a few (decades) years, so maybe it won't be such a problem to use ready-made MIDI libraries and finish programming others.
