Following up a suggestion in another thread far, far away, can I ask if anyone knows of a native RISCOS MIDI sequencer which has been / could potentially be ported to Pi RISCOS? I'm not looking for anything with audio recording / playback capability, just a multitrack midi recorder / player similar to first-generation versions of Cubase.
Obviously, such a port would either need to be able to recognise and run with a USB-> 5 DIN midi interface, or more ideally to be able to use the Pi's onboard UART with the addition of optocoupler input / output driver hardware.
I'm aware that there is apparently a high-performance port of Hatari (ST emulator) already working under Pi RiscOS, but I am assuming (perhaps incorrectly) that Hatari (Pi) hasn't been tinkered with to allow use of the onboard UART as one of the possible MIDI interfaces.
