Title: Re: [hatari-users] Question regarding Hatari and MANDALA.PRG

Dear Eero,

What you wrote back is probably useful for those in the know, like Robert maybe, but, sorry to say, I don't understand most of it. So, jumping to the first place I somehow could relate to, I went and downloaded Qsynth 0.3.6, which is about the same age as this MacOS, launched it and got this:

17:59:36.096 Qsynth1: Creating synthesizer engine...
17:59:36.115 Qsynth1: Creating audio driver (jack)...
17:59:36.126 Qsynth1: Failed to create the audio driver (jack). Cannot continue without it.
fluidsynth: error: Couldn't find the requested audio driver jack. Valid drivers are: coreaudio, file.
17:59:53.144 Qsynth1: Destroying synthesizer engine....
17:59:53.145 Qsynth1: Synthesizer engine terminated.

I don't have no idea what this means, never heard of a "jack" in relation to my Mac besides the physical ones I plug into the computer.

But even assuming that I could get any further, I don't understand this part of your following instructions either:

> * Select "synth input port" from the SDL GUI MIDI output selection

- tried to look up SDL in Wikipedia, and met a bunch of entries that could or could not mean anything in this context.

For the rest, of what I do understand:

> Hatari defaults for ST.

As I wrote in my first post I haven't had an ST for over two decades, so I wouldn't know what those defaults are and how to set them in Hatari.

> EmuTOS v0.9.12 release.

Assuming it's the same as the “emutos-512k-0.9.12” -> "etos512k.img" I downloaded, I also have not a clue as to what

> Hatari is naturally built from latest Git commit
which you wrote afterwards actually means.

Still hoping...

I tried something else than Mandala with PortMidi
(Sequencer One), and that didn't work properly
with it.  PortMidi complained about invalid MIDI
event data at Sequencer program startup, after
which PortMidi connection is closed and nothing
else will go through...

Please run Hatari with "--trace midi" option and
check whether it complains about write errors.
And if yes, what error number is reported by
PortMidi write error before that?
