Quadrature Sine (2020)
Quadrature Sine (2020)
Just about to be released (price likely similar to CVCO - EDIT - £180).
Similar to the old SYN2B but with Tune/Fine instead of the 10-turn dial.
Only two outputs Sin (0deg) and Cosine (90deg) as most CV inputs can easily invert for the 180/270 phases.
FM is either Linear (AC coupled) or Expontential (which has +ve or -ve polarity switching)
Yes, Freq-Shift is slightly in mind, though no renewed investigations as yet - there is a header on the back which should link to a future expander for this.
Waiting to calibrate the first batch..

When you switch to sub does it take a while to get going like the old SYN2B?

Re: Quadrature Sine (2020)

definitely want one or two of these in my life! Nice array of switch options
Great start to the year for BB blues, been rearranging my modular set up quite a lot to make room and money for new offerings - continue bringing more joy to the world Tom!

+ 1000000 for the freq shift expander!

Beautiful
I guess I’m gonna need one of those

Re: Quadrature Sine (2020)
So many awesome modules coming. So excited Tom!
Re: Quadrature Sine (2020)
when can we start peppering you with purchase requests? 

Re: Quadrature Sine (2020)
Yes, that's standard - oscillations build up quickly at the top of the LFO range, so best to give a quick push (eg. with +10V to V/Oct input) when first powered on. Once oscillating normally, you can switch between ranges no problem.chrisdermo wrote: ↑Wed Feb 26, 2020 10:17 am

Re: Quadrature Sine (2020)
Hi all. I can appreciate, conceptually, why it would be good to have sine waves 90° out of phase from each other, but I'm not sure I understand how to best use them in a patch. Could anyone give some basic examples? Or perhaps I'm overthinking this and it's just always good to have sine waves available. Thanks!

Re: Quadrature Sine (2020)
So you can draw circles on an oscilloscope
That's my appeal, anyway...

Ah, of course! I knew I was overthinking it.

Re: Quadrature Sine (2020)
The 90 degree thing is nice for LFOs. One output is just starting to reverse direction (up/down) when the other is more rapidly crossing zero. So imagine one is panning your signal and the other is working a filter or wavefolder for that signal. The coordination of those effects makes them seem less like arbitrary decorations.

Or laser.. I'd forgotten that we had a quick play around that at EMS in Stockholm some years back.bitSmasher wrote: ↑Sun Mar 01, 2020 1:16 amSo you can draw circles on an oscilloscope![]()

Yes, agreed, quadrature phases feel most useful for me as LF modulators - though also one trick for the Linear FM is to feed one wave back to self-modulate - generates a near saw with one wave and pulsey-sine (pic needed!) on the other.

Re: Quadrature Sine (2020)
so much good stuff from Tom!!! Ugh Im so broke right now!!!!! Need to start selling off some stuff as the bug stuff makes me the happiest.
works for Darkplace Manufacturing
Re: Quadrature Sine (2020)
Great ideas, guys; thanks! Got my brain pointed in the right direction. Now I just need to to get one!

Re: Quadrature Sine (2020)
If you make a new shifter please make it compatible with the old quadrature of possible

Re: Quadrature Sine (2020)
As just discovered in another thread from a hordijk lecture, you can feed the cosine output back into the linear FM input for waveshaping from sine to saw passing through all harmonic series en route.mIgmOd wrote: ↑Sun Mar 01, 2020 1:06 amHi all.

Re: Quadrature Sine (2020)
+1 if possible, please make the expander be compatible with the old design! It would be amazing!
Re: Quadrature Sine (2020)
I just checked the files and pretty sure there wasn't a 2pin output header (sin/cos) on the original - perfectly possible to hook up wires to the output sockets though
Re: Quadrature Sine (2020)
I've been hammering my pair of originals this last week along with the Freq shifters - great modules!
