Hi Keropi- […]
I was hoping you could give some advice - I haven't used the MusicQuest in a while (been playing games on t TNDLPT for the last several months), but now I have tried to use it again, I am getting no midi out.
- there is definitely a signal of some kind as the midi switch I am using has a green light that comes on when the PC is powered on, and goes off when it is off. So cables are connected OK.
- I am using default IRQ2 and port 330.
- I have tried with nothing loaded, no emm386, no mouse driver, still same.
- No other sound card installed.
- Games detect the existence of the MPU. E.g. in DN3D setup, it thinks there is something on 330, because if I change to 300, it says not detected.
Let me tell you a story about my weekend, and y'all can decide how much of a coincidence this is. (To relieve any tension I will state up front that my card is fine.)
My card is brand new. I first tested it in my P200 system, then moved it to its real home, the 386 pictured a couple of posts up. This all took place a week ago, and everything was dandy.
Last night I was testing a few games, using an MT-32 and a TG100. Things worked, then they didn't. I run through a MIDI Solutions Quadra Thru, so like you I could see the MIDI signal going out. Not only that, the screens on my MIDI modules were lit up with activity. It was like all MIDI volumes were at zero. The obvious troubleshooting step is to look at my audio signal path, and I thoroughly ruled out any issue there. Rebooting all hardware ended up fixing the issue.
Putting that mystery out of my mind, I powered down to put some stuff on CF. On next powerup, pop!
Obviously, I am not suggesting the card caused this. One of these has gone before and I was too lazy to sweep through and do a recap, so I'm not overly surprised this happened. But is it possible that an unstable voltage was causing weird issues with the card? And could that be the case for you too?
I'm not smart enough to answer that - just spitballing considering the coincidence here.
 The card is now back in my P200 and functioning perfectly.
