285e Frequency Shifter Balanced Modulator (EXAMPLES)

Post by djangosfire »

Here we go... please feel free to add a new video of how YOU use the Buchla 285e Frequency Shifter Balanced Modulator module... add it to THIS thread.

It can be simple, complex... test tone.. music.. it doesn't matter - just share it here... and comments are cool too.

Lets get inspired!

285e Frequency Shifter Balanced Modulator - Examples 01


Starting up a casual series of Buchla 200e module videos, that feature examples of possible use and sound!

Today I am featuring the Frequency Shifter section of the Buchla 285e.

Basic patch setup:

- StudioH “Dual Programmable Oscillator” as the audio source
- Buchla 266e, 281e & StudioH 254e as CV sources
- Audio is captured from the Buchla 206e Six Channel Mixer output, direct to DAW

Cheers!

Thanks for the 285e tips and great thread idea!
That feedback patch sound is :headbang:

A challenge for the wizards, what good can be had from the
audio fm function of both the FS and ring mod sections of this module?

Although the module’s core sound is all sweet baby Jesus analog, the
audio fm on each section is plagued with a scratchy digi digititis artifacts.

I’ve tried to make use of this sound over the years but usually end up not using this feature.

Anyway, still one of my favorite 200e modules!
You rock Adam!

a few quick notes ideas re: 285e FM input

- FM only affects the internal 285e VCO's
- if you want a more extreme FM sound, try using an external VCO... and apply the FM to the external VCO directly


285e FM patch idea for the Frequency Shifter section:

1 - you can get great percussive tuned sounds by patching a LF square wave (from a 261e MOD VCO or Studio.H DPO) to the 285e INPUT. Then try using the 285e internal VCO pitched up to a higher frequency. The LF square wave will "ping" the freq shifter.

2 - Take a spare 292e channel.. set to VCA mode, patch this 292e channel into itself: output to input feedback loop (with no other signal applied). From that same 292e channel, patch the output to the 285e FM input. As you open the 292e, you will create audio feedback that has a great affect on the 285e FM.

NOW..... to make it a rhythm, and a bit more interesting...

3 - send that same LF square wave from your VCO's banana jack output, to trigger a single shot 281e channel. Set the 281e channel for fast attack, slow decay (or whatever). Then send the CV out of that same 281e channel to open and close the 292e feedback channel (which is still patched into the 285e FM input).

I tried this patch today, and instantly usable rhythmic insanity :)

Maybe someone else can try this patch and share the video here in this 285e thread :) I'll try to post later too - but hope to see/hear others share too.

Thanks for posting! I love it. Definitely this is the longest and cleanest 285e demo I've come across, and I've been looking for years.

One patch that I'd love to hear from a 285e, or the plain old 285, having never used one, is patching external audio like human voices or a pop song, or any sort of acoustic recording with complex harmonics, where the artifacts of shifting frequency relationships are accentuated so dramatically. This is what I find myself using FS for the most.

Here's how I explore feedback with the 285e. The patch is pretty simple

Cool thread, looking forward to more additions :party:

Very cool 285e feedback patch Todd :sb: :sb:

Hmnn.... I wonder how this extension of that patch would sound/work:

- same feedback setup with the 285e.... BUT
- send 285e Down Output to 296e Odd Input
- send 285e Up Output to 296e Even Input
- Send 296e Odd Output to Left 206e Channel Input
- Send 296e Even Output to Right 206e Channel Input
....THEN:

- experiment with sending one of the 296e Envelope out CV's back to the 285e Freq Input CV.....

??? unlock the secrets of the Universe?? or make noise? Lets find out...

Today I’m further exploring a Todd Barton suggested 285e feedback patch found here:



And am extending the idea to include a 296e!

Basic patch setup:

- 285e Down Output into 285e Signal In
- 285e Up Output into285e FM Input
- 285e Down Output patched into 296e ODD Input
- 285e Up Output patched into 296e EVEN Input
- 296e Spectrum Transfer set on to both ODD to Even, and Even to ODD
- 296e Display set to Envelopes
- 296e ODD audio output patched to 206e Channel 1 Left
- 296e ODD audio output patched to 206e Channel 6 Right
- I patched 296e Envelope Out CV from channel 15 back into the 285e Frequency CV jack

Audio from this video was straight out from the 206e main, through the console, into DAW (which I used some UAD EMT Reverb).

Now, go explore some sounds!!

Cheers,
- Djangosfire

Friggin' cool Adam!! Great sculpting ideas. OK
I know what I'm doing tomorrow, will have to transplant
the 296e closer to the 285e and explore.

Thanks for this!

That feedback video with the 296e negative voltage was really cool!

Here’s a simple thing to do with the 285e.

Here I’ve got the DPO/258e putting sines into the signal and reference inputs of the 285e.

Using the 210e, just mixing a little of the up and down outputs back into the input of the 285e can get gnarled and blown out sounding.

I just started with a 281e sweeping the frequency of one of the oscillators
Turned up the gain on the feedback going back into the 285e with the 210e, nasty!

Then just replaced the the sweeping 281e with a 250e sequence.
Even with this iPhone mic the filthy comes through.

Thanks for the 296e 285e patch Adam. Gunna try that!

You gotta love that filth! :sb:

I just tried to replicate this patch only with a 285r eating sines from a 259r and a cem3340 oscillator. It's far from as nice and dirty as missingtwins patch, still you get the idea..

Nice patch @audioCTRL -- that feedback gives it punch and crunch!

Here's a little offering riffing on some of what Adam did and opening further exploration.

I like that patch, Todd!

What are you using for reverb here? It sounds like a modulated (fading in and out) spring?

Thanks! It is a Max 4 Live convolution reverb in Ableton plus there is some auto panning. Of course it is a lo fi iPhone recording too.
