I will bring my Appendage for everyone to play with.

Here's my first crack at an Appendage panel. It's still a little rough. I post with hope that someone from Team Appendage® will offer some critique. Let me know if the control groupings don't make sense or if I've forgotten or mislabeled anything. This will be the largest panel that I've ever tried to etch, so I'd like to get it right the first time.
Great looking panel! I've made a few observations below, nothing major but I figured I would share them with you none-the-less
-The 'lower case' portion on the 'MIXED' label in the voltage output section is a different size font than the other outputs in that section
-'MIXED' and 'BEND' in the voltage output section need to be 'bottom justified' with the other outputs in that section
-'Norm.' and 'Re-Trig.' in the toggle switch section are right edge justified, they probably need to be center aligned like the other labels
-All the labels in the middle section (both rows) should be top justified _________________ Don't feed me Indian, you WILL regret it!

Just a little update on the project while Scott works on the Waveshaping projects so I will hold the fort down on this end of the Appendage testing.
All the changes that the team has agreed on are made to what will be the production printed circuit board. This is really going to be a beautiful board with versatile power interconnections to fit into many system. Whats left? I just have to do some trimmer juggling in terms of their orientations but everything else has been cleaned up, things added, and things removed, etc ....
Andy should be receiving a new Softpot as his bas bad. After receiving, he should be able to continue his testing.
Testing should be completed soon and the documentation process will continue.

I plan on putting the waveshaping thing on the side and concentrating on finishing up the documentation on the Appendage. Too many pies and not enough fingers. _________________ My Site
Hey everybody,
Got my new softpot yesterday!
I'l be back on the case ASAP. _________________ What makes a space ours, is what we put there, and what we do there.

Guess this thing should come with a warning label - I think each of the proto guys has been sick at least once (I've had three rather significant infections this year); the Appendage was going to make it's debut at AHNE today, but Bill was taken ill and couldn't make it (hope you're feeling better, Bill).
Here's a video of the Appendage Touch Sequencer I've started working on. Somewhere in the early mists of this thread, I mentioned the concept: the ribbon is divided into eight zones; touching a particular zone will activate a particular stage. Like a "normal" sequencer, each stage has an adustable voltage, so each of the "zones" can be set for a particular note. Of course, the circuit is set up so the sequencer can be clocked (more on the sequencer in a while - it's similar to the sequencer I discussed in the very beginning of the first Klee thread - the one where the Klee was "born").
Anyway, the Bend Voltage is mixed in, so that a "zone" can be slid up and down the ribbon, bendy-slidey-wise.
This video has the Appendage Sequencer controlling a single sawtooth VCO through the 2040 clone filter. The cutoff of the filter is controlled by the slide output of the Appendage itslef. The signal is also going through the Triple Wilson SVVCF at a low level. The Klee is providing accompaniment by controlling another signal through the same Triple Wilson SVVCF. The TFS output of the Appendage is controlling the BP frequency of one of the filters in the Triple SVVCF, so when two pressure points are "spread out", you can hear the Klee accompaniment timbre modified as well.
The Klee, BTW, is controlling both MS20 filters in my dual Schmitz MS20 filter - they're self oscillating and the combined output is run through the CGS wave multiplier before it runs into the Triple SVVCF. The Klee's controlling an EG, and the Appendage is controlling an EG for it's single sawtooth voice (for filter and VCA).
Dunno if this will be in stereo or not. My video format is not HQ.
This is where I wish that I travel to work by bus or train, so I get a chance to read the documentation, uninterrupted, when released - nobody saying "could you just............"!!

That looks like so much fun!
Will it be an add on board for the Appendage?
Well, considering the 20 pin AUXILIARY connector on the Appendage PC board has the GATE, TRIGGER, SLIDE, INIT, BEND, and TFS voltages on it, it could very well be an "add on" BUT will leave that up to Scott I have to also get moving on the "CV2MIDI" that will add MIDI NOTE ON/OFF & CC messages in response to the Appendage's analog and TRIG outputs.
The team members and I, have started to talk about target dates for the Appendage release but some behind the scenes "chat" needs to take place for that to solidify.
As for illnesses, well, this has been a bastard of a year for all of us team members as Scott pointed out. Personally, this weekend, Robin and I drove 12 hours to and from Bolton, MA to attend AHNE and do an Appendage demonstration but Robin and I both got sick and returned home from the trip with nothing accomplished. I had it all planned with a new addition to the demo sound system, a KRK10S 225W Subwoofer to add to my KRK Rocket RP-5 powered monitor speakers. Oh well, Sometimes life throws a curve ball at you BUT the show must go on and I will just plan another "show and tell" ... NOTHING CAN STOP ME !!!

Here's a longish composition I recorded late last night using the Appendage and the Klee Sequencer. If it sounds broodish and bleak, that means I properly communicated my state of mind at the time
It was all recorded "live" (as if one couldn't tell), from a single patch on my synth. There are CGS drums in there, too. I videoed the performance, but it's around 14 minutes, so any YouTube video would have to be abbreviated.

Thanks, Jan. It was a moody late night thing - hadn't touched the synth all week, and needed a diversion. I patched it up (actually it was almost the same patch as my last video) and turned on the camera and recorder.
i want one! not that wouldn't have enough on the pile... _________________

Oh, it's coming, it's coming....
Vimeo allows videos longer than 10 minutes, so I uploaded the video there.
The Appendage is controlling the breadboarded Appendage sequencer, so the ribbon is set up into 8 zones. The attack time for the EG the Appendage is controlling is set for a fairly long time; the decay is long, but not nearly as long. That allows me to open up the Appendage louder or softer by how long I press on it, so I do a lot of "nudging" to add touches here and there to the progression of things, occasionally holding it open longer for louder passages. It's hard to see from the angle of the camera and crap resolution, but when the ribbon is pressed, there's a little Gate LED that comes on in the Appendage panel in the middle of the farthest most rack, right above the synthesizer. It stays on as long as pressure is detected on the ribbon (and the gate is therefore high).
TFS is controlling a VCA that passes a rapid triangle LFO on to the filter control, so a wide spread of two pressure points gives it a rapid sputter. Inverted bend opens up a VCA that's passing the pulse wave of the same LFO, and that's mixed with the sequencer output, so a slide that starts at the top of the ribbon drops the pitch of one of the VCOs, but also increases the pulse modulation - at a certain point the pulse modulation overcomes the drop in pitch and starts to pull the pitch back up. The non-inverted bend voltage is mixed with one of the two VCOs the Appendage sequencer is controlling, so one VCO stays at initial pitch, and one starts at its initial pitch and bends with position on the ribbon.
the ribbon is divided into eight zones; touching a particular zone will activate a particular stage. Like a "normal" sequencer, each stage has an adustable voltage, so each of the "zones" can be set for a particular note.
Hi,will this feature be included in the final project?

Thanks, guys.
No, the sequencer is not part of the standard feature set, but, as it is now, it's a fairly simple circuit. I've just got the stage selection in; I just haven't had the time to put in any clocking to make it a full sequencer. In any event, I think Bill plans to incorporate the function in the planned Appendage quantizer, which will be centered around a programmed part, which I think is a pretty good idea. In the meantime, I can post the schems of what I have now - it's pretty straight-forward.
Here's a video I put up last week - guess I never posted it to this thread. It's the patch that spawned the patch of the last video. In this one, the two VCOs that are controlled by the Appendage are hard synced master/slave. Bend shifts the slave up in frequency, giving the synced effect. The modulation control is pretty much the same; different settings. The Klee is acting as a "normal" sequencer (it's processing a one bit pattern).

That piece just took me somewhere i didn't want to come back from.
