Thump Uploader

To download new drum sounds to your iPhone, you need this bit of software.

To create a new drum preset:

  1. You must create a folder in the "samples" folder of the ThumpUploader app.
  2. Give this folder the name of what you want to call the drumkit.
  3. In this folder you put your audio files.
  4. You must make sure they are "wav" format, mono, and 16 bit 44kHz samples.
  5. There must by 9 of them and they must be labeled 1.wav to 9.wav (case sensitive). If you don't do these things, it will not work!
  6. Start ThumpUploader and follow the instructions in there.
