You can use the built-in HW recorder to record audio (and midi); the audio is recorded as a .wav file .
.wav files can be large and Contra Bombarde uses .mp3 files rather than .wav files.
If you use multi-channel audio in HW, you can select which channel(s) to record. Ideally you want to record a stereo channel which contains all of the sound outputs for the organ – often the audio output configured for headphones will contain all the sounds being played – is might be the best one to use. You configure the recording options in the HW audio output options. (Manual pg 140 onward)
You need to convert the recorded .wav file to .mp3 format to upload them to Contra Bombarde. You can do this using the free program called Audacity; there are a number of other programs which can transcribe .wav files into .mp3. Audacity may be downloaded from
https://www.audacityteam.org/download/; it works on both Windows and MAC systems. Programs like Audacity also allow you to adjust the level of the recording (which can be helpful if you have recorded at a low volume level. Alternatively you can use conversion facilities offered for free by some web sites (such as
https://online-audio-converter.com/); use the higher quality options (192kps).
Once you have converted the .wav file to mp3 format you can then log on to Contra Bombarde and upload the file using the upload tab.
If you also record the midi file you can upload that too – it does not need conversion but will only be playable as intended if the listener downloads it and plays it using the same sample set as you used when making the “recording”. Most listeners will probably want to hear the music as simply as possible so it is probably best to provide the mp3 file!
The HW manual gives details of configuring the audio output and information about the location of the recorded .wav files. (Select the .wav file to be 16 bit rather than 32 bit) See the HW manual pg 132 and following.
