Q: I tried to update Blofeld or to load a sound set, but it didn't work!

The soundset containing a xxx.mid file (ore multiple) that needs to be transmitted to Blofeld. If the installation wasn't successful, this is mostly because the transmission went wrong. Connect Blofeld directly to your computer, with no hubs or other hardware inbetween and with no other devices in the MIDI chain. If you're using USB MIDI, try using DIN MIDI instead or vice versa. Make sure that the latest OS is installed on Blofeld. Set the Sysex ID in the Global menu of Blofeld to 0 or 1. On mac OS, you can send a MIDI file easily by using the free tool “SysEx Librarian.” For Windows you can use “MIDI OX,” which is also free. You also can send it with a DAW like Cubase, Logic… (This procedure won’t work with Ableton Live and Bitwig, as these DAWs don’t support Sysex data). Connect your Blofeld through USB or MIDI to your computer. Load the .mid file into a MIDI track of your DAW and play it back to your Blofeld. Reduce the playback speed to 80 bpm and activate transmission of Sysex data, if necessary. Alternatively, you can use Spectre. Spectre is available in the download section at the end of the FAQ list. In Spectre, click on Audio/MIDI and select the MIDI out connection where Blofeld is attached to. Now click onto Upgrade… in the main window of Spectre and select, which .mid file you want to transmit.
