DeviceList Problem in rtMIDI
BlitzMax Forums/Brucey's Modules/DeviceList Problem in rtMIDI
| ||
| this is a bug report for brucey: I found a bug in the rtMIDI.mod. [EDIT 12h later] the code doesn't crash anymore. It only remains a String-Problem The rtmidi module has worked perfect during the last weeks. Now I started to test it with different (external) MIDI-Devices. With one device from "www.thomann.de" the code crashes. I am not able to send you a code which could demonstrate it, because you would need to have this device to see it. But I try to descripe what happens. The device is called "Swissonic MIDI USB Interface". It has one IN and one OUT. The problem is, that its device name is "USB-Audiogerät" with a german umlaut "ä" in the name. When I try to list the device names of the midi-out-port the result is something like this:  This seems to be a memory violation. Where does the right part "...ient" comes from? At first the problem was, that the code sometimes crashed in the moment of filling the combo-box... or sometimes in other parts of the program. At the moment it seems to run stable. But I need the correct and complete device names for a users combo-box, where he can select the device. When I try to open the MIDI-OUT i get errors like this:  Also in your Sample-Code attached to the rtmidi.mod the device names are returned incorrect. See picture above. Could you please have a look on the source code of rtmidi.mod, whether you can see a problems with german umlauts? Last edited 2011 |

| It's a bug with rtmidi on Windows - not handling unicode characters properly. I think I have a fix for it. |
| ||
| I've uploaded a fix to SVN. I couldn't test it exactly, as obviously I don't have a device with such a name, so instead I wrote a test app which replicated the issue, and worked out a solution which fixed it, then applied it to the RtMidi source, so it should work now as expected. |

| And released it - 1.01. It's also the latest RtMidi source too, so I expect there are other improvements in there also. |

| hi brucey, i did forget to tell you, that i had a nice contact to rtmidi author Gary P. Scavone. I informed him about the bug we found. He answered very friendly and launched a new update 1.0.15 in august. |
