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 use your MIDI2RCX, but if WAV2RCX can support
NQC directly, it is better.
I want to use NQC because it can be used for RCX or Scout, all my projects and
programs try to be used both for RCX and Scout + Micro-scout.
