Sequential circuits samplers

Call me a dolt, but I can't make sense of the MIDI implementation on 
this thing.  My main interest is to set up my Prophet to respond a 
certain MIDI channel.  I don't want splits, I don't need it to send 
anything, I just want it to respond to the sequencer and I want the 
equivalent to LOCAL set to "on" however that can be done.

I have the manual, I have read it, but since I've slowly been getting 
myself into the Prophet my head is not into the manual yet, if that 
makes any sense (in complex devices I find that unless the manual is 
exceptional, I need to read the manual and then start playing with 
the device before the manual begins to make sense, and then 
everything usually falls into place quickly and clearly).

Thanks.

mode 3A, they call it in the book, though it's the most widely used midi mode 
now. then select the channel. in mode 3B, the machine can be bi-timbral and 
you need to press "execute" to see the other channel setting. be aware, though, 
that the dynamic allocation should be on and a mono connection made to the 
machine for anything like "normal" behaviour in 3A; if it's off, or if you use 
left + right outputs, you'll either only be 4-voice polyphonic or have the 
sounds bouncing around the stereo image. 

duncan.

Thanks.  I could swear I set it to mode 3A but it wasn't working 
properly.  Oddly, too, although I had the switch in back set to THRU, 
it was still sending note and controller messages to the next synth 
down the line.  I guess I'll have to play with it more, but the more 
I work with my P2K the more I suspect it has an issue related to the 
Op ROM.

or it could be "digital" trouble of the other kind. I will stand corrected, 
if I'm wrong, and I haven't used my p2k in a while, but- I think you have to 
explicitly save any changes you make to a preset before selecting another, or 
everything (including the midi mode) reverts. could you be doing something like 
that maybe? 

it may seem counterintuitive to have this setting non-global like this, but 
these things were made when midi was young, and they thought you might use the 
thing in mode 3A some of the time and 3B some of the time, bi-timbral. I used 
to do this a lot, and have the 3A patch using a stack and dynamic allocation 
the fatten it up.

the switch on the back is weak hardware- I bridged mine with soldered wires 
to make it permanently through. but on the subject of it's midi output, the 
apreggiator is great fun with an analogue synth on the end of it.

duncan.

After some fiddling last night I got everything to work the way I 
wanted to.  I didn't have to save the preset after making the change, 
but I did have to make sure I put it back into preset mode after 
making the changes.  Also, yes, you are absolutely correct about 
the "thru" switch: I had to toggle it back and forth a couple of 
times for it to finally let a signal flow though it. It's probably 
shorted so one of these days I'll replace it with a more robust one.

Thanks for your help!
