Hi Thorsten! I wasn´t able to use MIDI-Ox.... mac user... but I had a look at the events, using snoize´s MIDIMonitor, Serge´s SysExLibrarian... and: I couldn´t find any CC or similar event,.... only the notes I seqenced were played back.... only one aspect confuses me: There were Note On events,.... but I couldn´t see Note Off events.. normal ??? Rev.: SID crashs DIRECT after the FIRST recieved note and got a "hanging" MIDI-note..... ..... seems like the Note Off event´s missing :o or what´s going on? Sorry for that shit :-\ but... I´ve really no similar Problems with my other synths, sequenced with the MPC... for example clavia nordrack 2, virus.... The only synth with a similar, but only sporadic problem, is my mfb-synthII as I reported in another post, a few months ago... I´ve testet the last beta version of 1.7 ,too.... so I´m getting confused,.... also I´ve never had problems using Logic to sequence the MB-SID (but I think, Logic sends Note Off events,... am I right?) Nobody out there with a MPC and MB-SID,... can`t believe it ;D Best, pwx
