I was thinking that this technique would also be very useful for
programming the PSIM as a quantizer.  The sequencer could feed in the
values of the desired output voltages.  

What I (and I'm guessing Mark too) am looking for is an interactive
interface, where I can change gate length, endpoints, etc while the
thing's running.

With a good control interface (ie, enough sliders, knobs and buttons),
the PSIM has the potential to be the PERFECT sequencer because it will
have MY software in it :)

BTW, I have to say (#1) the PSIM currently occupies about 85% of my
brain's CPU time and (#2) I am awed by the creative ideas this group
comes up with :)

Why don't you just take your analog sequencer and have it read 
by the PSIM as an expanded input device?

Take the ARP 1613 for example. Run the 10 volt output into a CV 
input of the PSIM-1, then take a PSIM CV out to the sequencer 
step input.

Then just read the input voltage from the first stage, store it in an 
array variable, pulse the CV out to the next stage, read that, store 
it etc. for all 16 stages. Since that ARP runs at audio rates, it 
would take only about 5 milliseconds to read all 16 sliders.

Then just do that other stuff in software using the 16 sliders as a 
programming interface. You could also read the ARP switches 
using the AUX input, or another voltage input.

Then you could use another voltage to determine which 
variables you were editing with the 16 sliders (for example).

Conversely you could use the 16 sliders to set 16 parameters for 
each stage of a software sequence of any length. 

The trick should work with any existing analog sequencer of any 
length, 8, 12, or 16.

_yeup_

I think it's clear that Andrew and I have had our experience with various 
sequencers, but there's been something lacking from all of them.

If we're guessing right that Brice is looking to do some sort of a control 
interface with the PSIM as a brain, then I think it's valid to make up 
wishlists.

The closest thing I've seen to heaven in a sequencer yet is Colin Fraser's 
P3 project (http://launch.groups.yahoo.com/group/analogue-sequencer/).

... I have one on the bench waiting to be built.

Now, that box is _VERY_ powerful and Colin's continuing to add features. 
But, it's MIDI and is either overkill or won't work for "simple" stuff like 
firing off a string of beats, or creating a complex wave generator, or a 
complex EG.

Yeup... That becomes a real beauty point here. Design the right controller 
interface and then let the users (easily) write code to let it drive the 
brain as they see fit.
