I decided to try a number of signals patched to my A150's I/O2 
(Normally Open) jack. I wanted to see which ones would trigger an ADSR 
envelope by bleeding through the O/I jack, even though nothing was 
patched to the A150's CV jack to close the switch.

Signals that DID NOT bleed through were:

A145 LFO Pulse
A147 LFO Pulse
A155 Trigger
A156 Trigger
A190 Clock
A191 LFO Pulse

Signals that DID bleed through were:

A155 Gate
A160 Clock Divider
A162 Trigger Delay
A165 Trigger Modifier
A190 Gate

What's even more worrysome is that I'm fairly sure that I've 
successfully switched an A190 Gate signal with the A150 in the past, 
so now I'm concerned that the A150 is actually deteriorating in this 
regard. I wish I could be more certain about this.

There was an earlier response from Dieter on this issue, in which he 
ascribed the problem to user abuse of the A150. I'm certain that he 
misunderstood the symptoms, though, because he was talking about 
signals patched to the CV input, rather than the switch inputs. In any 
case, in was in the middle of preparations for the Frankfurt show and 
he probably didn't give the issue a lot of attention.

I've sent a copy of this post directly to Doepfer by email.
