Today we dive into the last born of the 200t serie, the Frequency Shifter & Balanced Modulator Model 285t.
I've never had a frequency shifter in hardware before (I use the Ableton one quite a bit tho) so it was a bit of challenge to get into it but I found a great article that helped me a bit on Signal / Perfect Circuit, go check it out:
www.perfectcir...
Many crazy weird stuff but also some very subbtle and nicce sounding stereo effect.
Have fun!!!
I suggest everyone also check out the videos from the amazing @vgermuse • Tiptop 285t demos
And also this one by Cinematic Laboratory: • Tiptop/Buchla 200 Seri...

Crazy that this is only 1 of about 3 decent videos on this module on TH-cam. Thanks for diving in with it!
Slick sounds as usual, inspiring. Great demonstration! Hooray for Buchla. I like the panel spaciousness of 285 as well - inviting, digestible.
Hello from California.
Great deep dive into this module. Impressive capabilities.
Thanks for sharing, and best wishes for your continued success/fun with modular.
Looks like I have to make another Tiptop Bucha case!! No space in my other one. Love this Stamza.
Really good, man. Super helpful. I've watched it twice so far. Thank you!
Awesome
Nice video as usual. I’m looking forward to try this when mine arrives.
Got this and the 259 arriving tomorrow, can’t wait!
As always: excellent video !
Curious to compare this freq shifter withe the Doepfer one, and the XAOC too...
Dis,c'est complexe à utiliser le polyend Tracker?...merci pour la video encore une fois géniale et clairement expliquée.
Non c’est plutôt simple
I suppose you could get the variable amplitude/ring modulation using Maths to offset your modulator... I should try that. Nice video!
Yes you can but it’s not super Easter to dial in. I’m almost sure is a video showing this on the Make Noise channel
I think using a bipolar modulator in a standard (unipolar/2QM) VCA for a classic AM patch would not give the same result as offseting the same modulator in a 4QM (balanced modulator/ring modulator), or in a 2QM, for that matter. Offsetting the modulator (by +5V) would result in the VCA being open at least to some degree almost all of the time. The VCA in a classic AM patch would spend half the time closed and half the time at varying amounts of 'openness'. I don't know what the variable control actually does on the 285t (it may indeed be just offsetting the modulator) but I would guess that it would be doing something more like crossfading between (the signal through to) AM and (then on to) balanced modulation.
It is possible to patch your own variable AM to 'Ring Mod' conrtol though it would be a fair bit more involved than adding a variable offset to the modulator. I think there are a few ways to patch it (or, at least, a few variations of the patch). For instance one way would involve some attenuversion/offsets, 3 of the same type VCAs (unipolar, ideally with a linear response that are fully open at 5V and a mixer - a VC mixer may be another option), some half wave rectification (or full wave rectification depending...), a comparator and a switch, and some mults. You'd want to try and ensure the outputs of the VCAs and/or mixers give unity gain when they should (i.e. with +5V present at the CV input), so depending on what you have you may need to be able to add a bit of gain. If you want I could try and give you a step by step patch guide, but I'll warn you, it would be quite lengthy (maybe a bit much for a TH-cam comment).
@ good information to have. For now I’ll stick with my limited resources and my janky AM, but I’d really like to build or buy some Serge modules in the future, so if and when that happens I’ll do some comparisons
@@chrissherman01 The knob on the 285t looks like a 3-way crossfade, crossfading between an unmodulated signal to an AM signal then between that and a RM signal. Patching your own (2-way) crossfade between just AM and RM would be a fair bit less involved. You could even just mix between the AM and RM signals, which would require manually controlling two knobs or sliders. If you don't have or don't want to use a 'standard' (2QM/unipolar VCA) for doing the AM I think you could use Maths to half wave rectify your modulator signal and then crossfade between that and the non rectified modulator signal in a 'RM' module. If you mult and send your modulator through ch 2 or 3 of Maths, and use the 'OR' output you should get a half wave rectified version of your modulator (you would need to null or remove all the other channels of Maths from the Summing bus). Mixing (or crossfading) between this half wave rectified signal and the original bipolar modulator signal and then sending that to the CV (modulator) input of a 'Ring Mod' (balanced modulator/4QM/bipolar VCA) module should get you pretty close to what moving the 285t's knob from 12 o'clock to full CW does. I say pretty close because I have a feeling that there may be a small voltage drop on the 'OR' output on Maths (not really a big problem) and a 'Ring Mod' module isn't really going to fully close with a what is meant to be a '0V' signal. A better method would probably be to just crossfade (or mix) between the outputs of a unipolar (2QM) VCA (ideally with a linear response) and a 'Ring Mod' module if you did have both types of VCA to hand (obviously you'd need to mult both the 'carrier' and 'modulator' signals to do this). Unfortunately voltage control of the crossfade would be a bit more involved and require VCAs and a mixer (or equivalent, such as a VC crossfader).
Nice video as usual. Just a quick remark, 6:40 I don't think that ring modulation changes the phase. Ring mod is also a form of amplitude modulation but for the positive and negative sidebands. In AM with a 'normal' VCA it only affects the positive part. But I'm also not an expert just on this. I'm sure someone can elaborate the difference a bit more detailed.
Phase is maybe the wrong word, it does change the polarity of the signal for sure tho.

In a small buchla themed case that has room for either a second 258t or a 285t, which would you reccomend?
The 285t would give a lot of fun sounds combining the 258t you already have so for variety sake that's what I would recommend. If you want big drones mostly a second 258t is great tho hahaha.
Après avoir abandonné l'idée de me faire un EASLE DIY; je dois quotidiennement lutter pour ne pas tomber dans l'achat d'un double mantis plein de module tiptop x buchla. Dans cette lutte intérieure, tes vidéos n'aident absolument pas, saches le... haha
Hahaha tu m’étonne
I’m a little disappointed about the ac/dc coupling thing. Should be the same as the rest!
Well the 292t is also AC coupled, it make sense for this kind of modules I think even tho it’s true it could have became an interesting VCA option in the system if it was DC
