Thanks for your help Chris! forgive my ignorance, but I am not sure what you mean. I've installed pmidi and what I get is: ~$ pmidi -p 128:0 No.19.mid Could not open file No.19.mid Doesn't that mean that the iPad is not seen? where: ~$ lsusb Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub Bus 002 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub Bus 003 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub Bus 004 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub Bus 005 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub Bus 006 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub Bus 007 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub Bus 008 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub Bus 003 Device 002: ID 0a5c:4500 Broadcom Corp.

Essentially the reason to use the iPad is because we have to make a demo where with our hardware we send midi commands and the iPad has a very good DJ application that can be used with a USB midi controller. So I wish to connect our hardware to a Raspberry Pi (or similar) via BLE and then the board (Raspberry Pi) to the iPad through USB cable. I think the weak point is communication from the Raspberry Pi (or PC) to the iPad via USB. I could actually remove that if I find a decent Linux/Python application that acts as a DJ deck. I am having a look at pygame.midi as well, but I am not sure how to link that with a USB cable. mik -- http://mail.python.org/mailman/listinfo/python-list
