New #F256K2 from #Foenix Retro Systems has MIDI in and out support - good use case for the MIDI selector I designed recently. I can switch between a 25-key portable keytar or a full 88-key controller from m-audio. I've got *plans* for the F256K2...

2nd example for my standard MIDI file parser and player I coded in C going on my F256K2 that uses a sam2695 chip from Dream. This code was ported from my own from the Mac 68k world.

I improved my C coded midi player with cute, snappy status characters that fade in and out.

oh wow, I have no idea how to use this.

6809 core for the F256K2 running NitrOS-9.
This is brand new from today for the K2, months after being developped and used on the Jr2.

#F256K2 finally got my spectrum analyzer part of my C mp3 player going on my 8-bit mode F256K2. That took a lot of tries and guesswork.

[F256K2] Spectrum Analyzer with mp3 playback
The F256K is from Foenix Retro Systems: https://c256foenix.com/ It is an 8 or 16 bit machine being able to swap around the CPU with a 6502, 65816 or 6809. This playback program was coded with llvm-mos C adapted for the F256 machines in 8-bit mode. https://kangaroopunch.com/view/ShowSoftware?id=13

Glorious madness of all these controllers working at once. I just added 2 NES pads and there's room for 3 more SNES pads. #F256K2 from Foenix Retro Systems
