The question was about the interaction of programs inside a combi.
Here's the file.

I was in a hurry and couldn't find a way to save only two combis and three programs,
so here's two combis and three programs and two whole empty banks in a 2Mb file. o_O
Don't overwrite your programs, make a backup if not sure.
The combis are in bank User-C and programs in User-B.
Combi U-C000: Karplus-Strong Test
Feedback alert!
This combi can produce very loud feedback if adjusted incorrectly, keep the volume down when editing.
This is a quick Karplus-Strong string synthesis test I made some time a go while reading
a book about synthesis techniques, "Sound Synthesis and Sampling 2nd ed. by Martin Russ".
This combi uses two programs User-B 000: Noise burst and User-B 001: Audio THRU.
The Noise burst is used to feed signal to the audio loop that includes 2ms delay
and EQ. And the Audio THRU routes the signal back in to the system creating a feedback loop.
You can try to modify the 'algorithm' by changing the EQ or swapping it to
a non-linear amplifier of your choice. Pitch is controlled by the delay and is quite
inaccurate, change the L and R delay together to change pitch and separately for nifty effects.
To play the synthesis you have to hold sustain pedal to hold the Audio THRU open, and
then saturate the system by pressing keys repeatedly, it takes about 40 notes to begin.
It is not very refined system, but it gives the idea and is good basis for further experimentation.
Combi U-C001: MS-20 S&H Example
This combi uses the program User-B 002: MS-20 S&H to chop up any program in the 1st Timbre.
The MS-20 is wired from EXi audio in to Sample & Hold, try to change the clock modulation
source from saw to square to get a different effect. Or re-wire the whole thing completely.
You have to edit in program mode and listen in combi mode, but you don't have to save in
between, just don't change the program.
The clue is to use the BUS system for routing the audio, I used the Rec1/2 bus in the
Karplus-Strong test and Indiv. output 1/2 in the MS-20 S&H Example.
As I have stated, the possibilities are endless.
I love the OASYS.
