Hi Jens, Very true. MIDI was an excellent solution at the time and made good use of limited bandwidth. But I think as MIDI got extended it got too complicated, and now with software music systems we don't have such limited bandwith anymore. The 8-bit messages are looking dated as far as simplicity and especially resolution goes. The MMA are addressing the resolution aspect with "High definition MIDI", but it's implemented as SYSEX messages and therefore just adds more complexity to writing a comprehensive MIDI implementation. I hope in future we'll have a simplified system...instead of CCs and RPNs and NRPNs and SYSEX Controllers, have a single unified controller with a 32-bit Controller-Number range. Map all the existing MIDI messages into that range. NEW-MIDI would have only one message type, it would look like.. [Timestamp][Channel][Voice Number][Controller-Number][Value] Anyway, I got way off-topic. My intention was to say that LV2 may not need a per-note control extension because MIDI already has it via "Key Based Instrument Controllers", which is a SYSEX message for sending a CC to one specific note-number. Best Regards, Jeff
