This is Spectre, a small tool for uploading sound sets or firmware updates to your Waldorf instrument.

First, go to Audio/MIDI Settings and select the target device as your MIDI output.

Then, click on Upgrade..., select the .mid file you want to transmit and Spectre will dump the file via MIDI.

If you are transmitting a new firmware, DO NOT STOP THE TRANSMISSION ONCE IT IS RUNNING. This might render your device inusable.


==========TROUBLESHOOTING==========


In case the transmission goes wrong, please check if your device is on the newest OS. Change the cables. When connected via USB, do not use a hub inbetween. Or use a different computer.

If Spectre does not work for whatever reason, try transmitting the provided .mid file with your DAW. Load it into a MIDI track and use standard MIDI playback at 60bpm playback speed to play back the file to your device.

When transmitting samples to a Blofeld with SL License, a stylized waveform image will be displayed. If this isn't the case, you may stop the transmission. Go through the steps above and retry.

Spectre might be falsely detected as a virus by some antivirus software. If this is the case, try adding Spectre as an exception into your software or transfer the file with a DAW as described.
