So you can get the average tempo by measuring the number of MIDI ticks per minute and dividing by 24. The tempo must not be changing. > 2) how to send standard midi message to set new bpm? > there's no such message. MIDI allows only one master that continuously gives the tempo. The solution would be to put your device in "slave mode", and to put your software in "master mode" so you can choose the tempo. -- Alexandre _______________________________________________ Linux-audio-user mailing list Linux-audio-user@xxxxxxxxxxxxxxxxxxxx http://lists.linuxaudio.org/mailman/listinfo/linux-audio-user
