To import your own songs you will need to download and install two programs. HxD [ https://mh-nexus.de/en/hxd/ ] OpenMPT [ https://openmpt.org/download ] if you are using a mac or linux machine you will need to download wine Run OpenMPT and goto [ File>Open... ] and open your .mod file. Next Select Samples and hold shift and click save sample (the floppy disk icon) and save the sample in the .wav format (I recommend saving the samples in an empty folder because there can be over 30 samples) Next Select [ File>Export as MIDI... ] and select midi programs the same number as the instrument ( instrument 1 is MIDI Program 001, instrument 2 is MIDI Program 002 and so on) Run HxD and select [ File>Open... ] and open the .mid file you saved earlier. Then Select [ File>Export>32 bit Intel Hex ] but save it as a .txt file so you can import the file into scratch. click " See Inside " to go to the scratch editor. click the green flag to start the project and press [m] to bring up the Toolkit Menu and then press [2] then type "1" into the textbox that appears. Next press [1] to Import a MIDI song then in the editor right click where it says empty and then click [Import] and open your .txt file you saved in HxD. Type in the song name then press enter. Then Select the "MIDI" sprite then select [Sounds] at the top. Delete all of the Built in sounds and add the samples you saved from OpenMPT. then make 9 duplicates of each sample but keep the duplicates together don't mix them with other samples. If you did this correctly then when you click the green flag again you should get a correct sounding file.
