Hi all, 2nd time typing this because clicking on something erased my post. I'll try to keep it as short as I can, again.
I purchased a Synthaxe a month ago from someone who also didn't quite know how to use it. When I tested it, everything seemed to work. The Synthaxe can only produce sound when connected to a synth VIA midi. I don't have any synths so I tested it with my laptop (Roland Edirol UA-25 MIDI IN into Sonar via USB). Seemed to work great.
The way the Synthaxe works is the controller is connected to the floor unit/power supply, which has a midi out for testing purposes I believe. A console that stores certain parameters/tunings/patch changes is also connected to the floor unit.
The console has 8 midi outs, as well as a midi thru and a midi in. This is where you're supposed to connect a synth to. It has 2 modes, Poly and Mono. In mono, you can do a variety of things, like assign a midi output and midi channel to each string, and use 6 synths. I use poly mode.
The issue I'm having is, it ONLY seems to work from the midi output on the floor unit, NOT the console. All 8 ports do not output info, no matter the channel. This isn't a huge deal, but I can't tell if its some incompatibility, or theres an issue from the console. None of the ports look bad, and any time I change information on the console, it outputs correctly on the floor unit.
Here are two things I tested. I heard back in the mid 80s when this was released, because of all the information it outputs, it would crash most DAWs, except Cubase. I downloaded an Atari ST emulator, got Cubase 2 and same issue. I could record and playback data from the floor units midi, but still wont receive data from the console.
The other thing was I used MidiOx. When the floor unit is connected, and I change a patch, I get a SysEx message. Once I use one of the ports on the console, it DOES output something but it isn't the same. I get a midi instrument change. For example, on the floor unit, I change the patch to "01" and it sends a SysEx message, as it should. But with the console (Activating port 1, channel 1) and I do a patch change, it just changes the Midi patch to 01 (Electric Piano, I think?). Its sending it to channel 1, but even on the Synthaxe console, if I set Port 1, Channel 2, and patch change to 01, it does the same thing, and says its coming from Channel 1.
I should also note that the Synthaxe does have a way of reading midi information from the floorboard. I can hook up a midi cable from the floor unit (the one that works) to the MIDI IN of the console. That also works and I can view hex data, probably similar to MidiOx.
Sorry for the long post but its a lot of information. Its baffling to me and i've been hacking away at different things for about a week now. Again I don't have a synth to hook up the console ports to, as it was supposed to be intended for, but it does work
with Cubase 2/3. I only can't tell if theres some Midi data being filtered out because of a modern DAW/OS or because its coming thru USB? I also can't tell if the console is bad, but I get no errors, and everything I do does work (Change tunings, pitch bend sensitivity). It has to do with how the console outputs the midi and how the interface/VST receives it.
If further MidiOx data is needed or need pics of something I can provide it.
