Greetings All,
Long-time Cakewalk/Sonar user here.

I have a song which was originally created in SOP 3.5 with a MIDI track for Bass Guitar and IKM's "MODO Bass" loaded on it.

This original track had been duplicated, then bounced down to audio and the original MIDI/Instrument track was then hidden.

After the recent SOP 4.0.1 update, the track can be un-hid, but when the transport is engaged, no longer sounds the bass synth.
(This is the original, still MIDI data, Instrument track.)

The client sent me an updated part he wants me to drop in, so after duplicating the original bass midi track, the MIDI data was deleted, and the new MIDI file dropped in.

That one will not play either.

If I create a NEW instrument track, THAT one will play his new MIDI file.

I would still like to play the first one, so as to compare it with the new file.

So I tried assigning the MIDI from track 1 (the original) to the new instance of MODO Bass (track 2) but that will not play either.

NOW - if I create a NEW Instrument track..., then drag the original MIDI down into it, it will play...

Why won't the file simply play after it is un-hid?
Is hiding a track akin to Sonar's "Freeze Synth" function? Does it need thawed?

Is this a bug in 4.0.1?

Or, I am missing something in SOP4?

Any ideas? Suggestions?

Thanks,
MG
