Thanks for the information so far. Is there any NQC command similar to the RCX-code "wait until message"-block? --Tobias (24 years ago, 30-Mar-01, to lugnet.robotics.rcx.nqc)

Thank you very much! I think your utilities are evry useful! I don't know more about music, so I wan to ask you, if you can convert MIDI to NQC, why didn't you also convert WAV to NQC? Although I can convert WAV to MIDI using anothe utility, then (...) (24 years ago, 30-Mar-01, to lugnet.robotics.rcx)
