bubblesound wrVCO preview

Post by bubblesound » Mon Mar 29, 2010 2:07 pm

i've been getting a lot of questions about this for a while now. i wanted to hold off until i had built a prototype and had a chance to show it off a little.
as you can see we're thinking about releasing 2 versions at the same time. nothing is set in stone yet and i wanted to open this up to suggestions and comments before it was too far along.
spec:
18Hp and 6HP
triangle core, the same as in the uLFO, but there is a better, tighter expo converter in the VCOs as well as a few other components that needed to be up graded to stability.
range: high - around 1cycle- 20k
low - 30 minutes - 120Hz(this is still up in the air)
tracking: about 6 octaves
pricing: this is still up in the air, too. once the features and components are firm i'll have a better idea. but it will be competitive. we're shooting for the same ballpark as the planB VCO and Elf LFO

the audio clips are very straight forward.
1- saw sweeping through it's range
2 - pulse sweep with pulse width modullation
3 - triangle in triangle FM action. one wrVCO is running up its range, being controlled by my pro-solo while another wrVCO is FMing it. all triangle outputs.

I've been loving using my two uLFOs as oscillators. These aren't even out yet and I'm pretty much sold already.

ooooooooooooooooooooOOOOOOOOOOO LOoks awesome! I was just thinking last night that I wish there were more small vco options. 6hp sounds great.

edit: the fm demo sounds sick!

so with a range that low, does this supercede the uLFO?

nope. the uLFO still takes about 60 (60 Hz?) minutes to complete a cycle at its slowest rate. :deadbanana:

I really want to hear a medium speed sweep of the saw mod to hear what that does. That seems to be the main feature not seen in the uLFO nor other oscs.

Very nice sounding/looking,bubblesound!! :tu:

On a side note...any word on the reset helper module for the uLFO?

I am looking forward to this. My system needs oscillator with individual waveform outputs and clean sine (?).

Jack spacing seems very tight. For reference, Cwejman VCA-4MX is as dense I can handle with ease. However, 4ms Rotating Clock Divider is too tight for my liking: For example, Tiptop stackable cables cannot be inserted to "Rotate" and "Reset" at the same time. At the picture wrVCO seems to have similar spacing.

What to loose?

There are now four FM inputs and two associated switches! I could live with one 1V/oct input, one exponential input and one linear input. If I need two 1V/oct inputs, I use Doepfer Precision adder anyway.

I am not sure about all functions, but at least Sync Out seems unnecessary.

Inverted outputs could be omitted too. I have plenty of inverters in my system.

(All IMHO of course.)

Is the saw waveform supposed to have that glitch in the middle?

This 6HP VCO is a great idea. I'm looking for such a small VCO to use it as a lin fm modulation source. Targets are ZO and AO. Any idea about the depth of the small one ?

I was waiting fot the VCO as my "perfect one" since having the uLFO and then you come with 2 modules!

:tu:

Great, now I can put the bubblesound also in my small to-go case, for which I was looking for some small VCOs. :goo:

I´d buy three right now if possible, one full and two 6HP :)

First the Waveshaper and now this. :hyper:

Huh? Just get them in the right position and they go in fine. I don't have the module in front of me but I'm sure I've done this. They made them a very clever shape for just this kind of situation.

So full of win, it just goes to show that the supply of win in the world is unlimited, else win would have to be taken from somewhere else . . . *

probably about 2-2.5"(60MM-80MM). and the idea was from shawn at AH...

waiting on faceplates and pots. probably about 4 weeks or so.

audio sync syncs using a +-5V and the gate/clock will sync to a0-10V
SynthBaron wrote:Is the saw waveform supposed to have that glitch in the middle?
no, there are 2 trim pots on the right hand side of the middle PCB. the top one is a course adjustment and the lower one is a fine adjust. i usually have my scope at 1V/cm when i calibrate them.

well, the 2 FM are kind of essential for me, i would consider dropping one of the 1V/oct, and i agree that the inverted outs might be redundant, as is the sync out, since it's a square, too.
this is an early draft and i'll be playing around with it a lot over the next month or 2.
i'll keep you guys posted as i make changes and see what you think. the uLFO ended up being a lot better than it started thanks to your participation, i expect this will be similar.
and i will be doing mock up panels thanks to qu.one and his laser so we'll get a real idea of how tight things are pretty soon.

and i forgot to post the timeline for this. we're shooting for july-august. a lot of the heavy lifting is already done, but the details can really eat up the weeks.

thanks for the support and suggestions. i'll try and get a couple more audio samples up tomorrow. let me know if there's anything specific you'd like me to hear. i know my demos can be a bit on the clinical side, i'll try for some actual music at some point...
i've tried nothing and i'm all out of ideas...
