Author Choices...Examples?
Exuviae
Hello All-

The sound samples I've heard here are great, but I am more curious about the actual patching side of things...

Forgive me if this seems naive, but can you guys list a few patch examples of what you use the Choices for?

Is it a manually controlled CV source? Does it manipulate incoming audio and if so, how? How does using the inputs and outputs together work?

I am big on FM stuff and making CV delays puke...do I want this module as much as I think I do?

Thanks in advance!

I don't have any samples, but the Choices is DC-coupled, so it can be used as a panner, attenuator, buffer, amplifier, etc. The toggle switch is to set the input bias level for CV or AC use.
The inputs are switching jacks - with nothing plugged in, it is a CV source, with a patch plugged in it disconnects the internal source and just manipulates your CV or audio.
Somebody else will have to answer the rest. wink

Trust me man, they're great. It's the first joystick I've had with my modular.
I made these quick examples when I fist got it. The thing I like is you can set up very complex and touchy on the the edge of chaos type events and make tiny adjustments to shape what's going on. Give Flight money so he can keek making cool shit.

ok - I just threw down on one. I am a big fan of the PB too!

I'll try to be more clear about my questions...

I get that by patching the two outs to destinations in a patch, you can tweak in a "vector" type way rather than just knob up, knob down. But what is the purpose of the inputs? Give me an example...like...

So, you patch two audio signals into the inputs...does their signal then come out the outputs? If so, what does moving the joystick do?

Same for CV-then...if you patch two CV sources into the inputs, do they then come out the outputs and if so, what does the joystick do?

I get the outputs...just not the inputs and their relationship to the outputs.

Anyone?

Sorry to be such a newbie bewbie - but we all have to learn somehow help

I also just snagged one from AH. I've been holding back since I got laid off... but Surachai's vid pushed me over the edge. Thing looks useful as hell and mad fun for live performance tweaking.
Exuviae
yes, the video was cool for sure, but it didn't really detail the patch. I'm still wondering how to use the inputs...
surachai
Exuviae,
Sorry I didnt copy and paste the youtube information on the post above. It goes as follows: I've been meaning to make a quick video of the Choices and Plague Bearer modules together for some time because they're quite a dangerous combo. The patch is a bit complicated but essentially both the X and the Y axis outputs are going into mults, those mults are plugged into the Plague Bearers along with a Tip Top Audio Z2040 Cutoff. The audio sources are coming from Tip Top Audio Z3000's FMing each other. I used a combination of the room and line audio so a fan is audible.

As for the inputs, the manual can be found here: http://www.flightofharmony.com/choices.html

More specifically: "In: Input signal goes here. When a plug is inserted, the unit
automatically switched from internal DC source to the input signal. "
Exuviae
Cool stuff, thanks!

@ VanEck: I hope it serves you well!

LOL @ ring of fire console. lol

That was sweet, thanks again Surachai!

Surachai pretty much covered it, so here's a technical rundown:

    The signal chain goes as follows:
  • Input jack to the joystick pot (which is connected as an attenuator),
  • from the joystick pot to the inverting input of an operational amplifier (opamp),
  • the Scale pot is the feedback resistor that controls the gain of the opamp (0x-2x),
  • from the output of the opamp to the inverting input of another opamp (inversion + inversion = no inversion),
  • the Bias pot applies voltage to the output amplifier to shift the DC level of the signal,
  • from the output opamp to the output jack.

Thanks, everyone! Mine should be here Monday - going to be a late night for certain.

Well, I got my Choices and was only able to run it for a little bit to test, but it was much fun!

I really did only use the outputs so far, though. I'm still a bit lost as to what to use the inputs for...they can be either CV or audio, right?

I not so much a complete newb to analog modular as I am to joysticks, so again, everyone, please bear with me...

I had both outs going to the CV inputs on my Mini Wave and changing the Ref switches made things sound different. These can be switched for either CV or audio as I understand, but they seemed to 'work' in either position...is there a chance of using the wrong settings and hurting other modules?

Thanks!

I'm glad you're having fun with it. smile

You can't hurt it with the toggle switch. It just changes the reference level for the input opamp. When it is set to DC, the references are V+ and ground. In AC, the references are V+ and V-. I did this so it would have as much offset range as possible regardless of input signal.
VanEck
Yeah, i got mine today too. We played with it for about an hour to break it in, mostly using it with our Quad PB. Much fun.

The real fun will be tomorrow night, when we experiment with it live during a Four Pi Movement gig we have with Graveyards (Wolf Eyes side project). Shit is going to make ears bleed no doubt.

Already having many ideas on how to implement this thing with our Tyme Sefari for one... cross mixing between the pitched noise outs on the Zorlon to use as CV for another... very inspirational module for sure.

Flamed! Flight Of Harmony Flamed!

So i recently got a Choices and am currently getting to know it. I had the idea to use the Choices to manually crossfade between 2 audio sources. So, I put the switches to AC and plugged 2 different audio rate waveforms into the inputs. I plugged the outputs into a mixer and monitoring the audio output of the mixer. For clarity's sake, before going through the Choices, I first patched the oscillators output directly into the mixer and level-matched them.

My expectation would be that if I set the scale of both the Choices channels to zero, i would get silence at any given position of the joystick. This is not the case. With scale set to zero, I find that I always have sound in any position. Moving the joystick around does change the relative levels of the 2 inputs. But, the far sides of both the X and Y axis always still contain some leakage of the other oscillator, although not much it is clearly audible. Does this latter 'issue' (?) have something to do with the bias (or other) calibration?

Actually, that is why the Scale knobs do not have a literal zero position. The Bias knobs do, but Scale is 1 in the center, and + or -. With the current circuit, it would take a bit of work and extra components to provide a true zero output via the Scale knob, so it was not included. The joystick itself can zero the signals (definitely with the switch in the DC position), so duplicating that function seemed unnecessary.
