OK, perhaps I chose wrong words in my School-English

.
I know AD is not able to trigger other instruments.
I try to explain again:
I have a master keyboard.
Keyboard MIDI-Out is connected to the MIDI-In on my computer.
The MIDI-Out of my computer is connected to the MIDI-In of a sound-expander (Roland SonicCell). I do this because the Roland SonicCell has no MIDI-Thru.
For recording I use Samplitude.
OK.
I load AD as VSTI in Samplitude.
In the track-parameters I choose MIDI-VSTI-record and so on.
For example I set AD for recieve to MIDI-Channel 10 and I mute MIDI-Channel 10 on the Roland SonicCell. Last I activate Monitoring for example on track 1 where I want to record a AD-Midi-track.
Now if I choose MIDI-Channel 10 on my master keybord I can play on it the samples of AD.
When I choose another MIDI-Ch on my master keyboard I can play / trigger samples of my Roland SonicCell.
Everything perfect.
Now I enable RECORD in Track 1 (master kayboard is set to MIDI-Ch. 10) and record a Drum-MIDI-Take.
And now comes the problem:
After the drums-take is recorded, I want to record for example on Track 2 a bass figure.
So I enable record and MIDI on track 2, set the MIDI-Ch. 1 for ex.
But anything I do, after I have recorded the MIDI-Track 1 (AD), I can't get a MIDI-In signal to my Roland SonicCell.
I think I tried almost anything what seems logical to me.
It seems as if AD would swallow now the MIDI-Signals
Not even shutting down AD helps.
The only thing tha helps is to restart my computer.
So, before I didn't have find and solve this problem, buying AD-FullVersion is not very attractive for me
I hope that this explaining is understandable, I know it sounds very crazy.
