[LAU] Problem uploading sysex data to hardware synth

Hello everyone! I've got a problem uploading some sounds to my Waldorf Microwave XT. It's an old device, but it's made to receive patches and wavetables. I downloaded a couple of MIDI fies containing the necessary SysEx data from the web. But when using aplaymidi to upload them like this: aplaymidi -p 24:0 bank.mid I get nothing for a few seconds and then messages like this get repeated a couple of times: [1393510.800523] dump_midi: 20 callbacks suppressed In the end I don't find any difference in my synth. question: is it the synth, the MIDI interface or ALSA/aplaymidi. My MIDI interface in this instance is a USB -> MIDI adapter, just shown as "USB MIDI Interface". It's twin is called "USB MIDI Cable". So I can't tell you it's make and model. So far they've both served me well. Any suggestions? Kindest regards Julien ---------------------------------------- http://juliencoder.de/nama/music.html
