MIDI problems with Unisyn and Snow Leopard

Postby rwconsultancy » Fri Jan 01, 2016 6:32 am

Hi,

First of all, let me hold up my hand as a fully-paid-up member of the Luddite Tendency - it's 2016 and I've only just made the move from PPC to Intel! Even so, I haven't jumped all that far, just as far as Snow Leopard, so that I can still run a range old, but perfectly functional, PPC programs. One of these is Unisyn (latest version, 2.1.1).

Unisyn is running in its new home, but I can't say that it's running happily. I'm getting endless MIDI errors, mostly 'deviant data (unexpected status byte)', whenever I try to communicate with my synths. I'm going through a MOTU Express XT and the hardware side of things, apart from the Mac, hasn't changed.

I've tried re-setting the XT, trashing the Unisyn preferences and setup files, and even installing Midiquest in order to do a comparison. Midiquest runs fine, which leads me to think that there's nothing inherently wrong with the hardware.

I could of course admit defeat and just buy Midiquest, but that's definitely a last resort. Does anyone have any helpful hints or comments that might get Unisyn up and running?

Many thanks.

I admire your tenacity, but it sounds like it's time to spring for a MidiQuest license.

Looks like you've already tried all of the reasonable troubleshooting ideas. Any further troubleshooting would likely be "throw it at the wall and see if it sticks" suggestions — different MIDI ports, different MIDI interfaces, trying every different setting on the MIDI interface whether or not it has any apparent relation to the problem, etc.

Wouldn't hurt to reach out to MOTU support. I suspect they might have some basic troubleshooting suggestions that might get you back in action.

Good luck.

I'll give MOTU a try - I've found them very helpful in the past but was sort of assuming that no-one there will even remember Unisyn, let alone have any experience with it! But yes, worth a go.

The only thing that's putting me off getting Midiquest is the pain that I anticipate in trying to move all my patches from one format to the other!
