VC Bit Modifier Expansion Port Update.

I Asked Shawn @  Analogue Haven if there was any information on the possible future expansion for the A-189-1 . 

My friends, the future looks interesting.

Below, in Dieters own words, he explains what could become reality if there is enough interest:

we think about an expansion module for the A-189-1 that would allow  some
additional features, e.g.:

- digital VCA at the audio input (one would not need a separate VCA  at the
audio input for certain bit modifier effects, if you already worked  with the
A-189-1 you should try a VCA controlled by an ADSR at the audio  input, then
you know what I mean !). For this an additional CV input is required
(available at the expansion module)
- voltage control of the mode (e.g. if the rotary switch is in  position 16
the mode can be voltage controlled by an additional CV input  available at
the expansion module)
- digital ring modulator (similar to A-114 but digital with VC  sampling

So far there is no release date for the A-189-1 expansion module.  For now
the A-189-1 users seem to be happy with the available features. But we
wanted to be open for possible additional features. Of course the software
(i.e. the microcontroller) has to be changed too.

So there you have it. I just hope the future owners of this module with be as selfishly unsatisfied as I am & give their vote toward its creation until the expansion module because a reality. ;)

I want to crush you to bits...

And so I shall, in 16 varieties not less.

Well, technically 11 varieties with a few short delays loped in for good measure.... but who's counting?

I'm not qualified to explain this modules settings in a manner befitting its design so I'll let the moving picture below do the talking for the most part. For a proper explination of each setting I recommend Doepfers own A-189-1 page. 

I used a simple sine wave for demonstration purposes so you could actually see what the varied settlings were actually doing to the waveform itself on the scope. Some settings don't sound all that different from the previous or might not sound like much at all. This is mainly due to the source with which i'm feeding it. A static wave with no movement or harmonic content to speak of is not what some of these settings would prefer. Prior to recording this demo I was feeding it Princes' Lets Go Crazy. Trust in the fact that there is more to this unit that what is shown. 

While I was installing the unit I notice there was a nifty little pin connection point that was labeled "Expansion" on the PCB. I'm very curious as to what it is exactly that Dieter has in store for it.

Over all I'm very satisfied with this module. It does quite a bit (totally unintentional pun that i'm too sappy to now remove) for such a small footprint. But I will say this; it is not a Malgorithm replacment. Its hard to explain but with them side by side they are two similar means with slightly different ends. For those of you thinking of letting go of the Malgorithm just because this is now available please keep in mind it is a complimenting addition, not a substitution.
