Polyend Press Compressor

CB Clean got an internal SC Filter (you can dial in how much HP Filter) which also works on the external SC if you use one.

Really? That would be cool.
How do you set the internal SC? I find nothing related in the manual and even wrote them, a future feature request about this and they never answered something like ā€œbut it has an internal sc alreadyā€ but rather that they’re gonna consider it for the future? That’s weird

And the manual goes

ā€œ SIDECHAIN
Allows you to use an external audio signal to trigger the compression, useful for syncing to drums and other Instruments. When engaged, the compressor will follow the signal plugged into the 1/8" SIDECHAIN input on the side ol the pedal instead of the input audio.ā€

But if you guarantee to me that it does indeed has an internal SC and how it works - how do you set it This will make me seriously reconsider buying one…

Manual page 19.

Its the EQ poti while holding both knobs.

Ah! That is wonderful! So it is in the ā€žhiddenā€œ functions.I’m wondering why they didn’t tell me this in their email response
OK I think I’m gonna order one.

Thank You very much for chipping in.

Dont know, i mean maybe cause the SC thing is a little bit confusingly described as ā€œhow the env follower worksā€ which is in fact how SC acts.

I can“t say anything about this Polyend Compressor here but (sorry in advance for slightly OT) some thoughts about the CB Clean:
My guess is that it can really good act as a mixing and mastering compressor, its stereo and good sounding, but it also shines as a playful thing on single signals. The different styles of Comp (liniting, FF, FB), the EQ-modes and Physics things and also the Dirtmode on top lets you try and play a lot. Also its more listening carefully than reading numbers on Attack and Release and Treshhold potis what maybe is a disadvantage for someone but for others its more helpful in learning to use a compressor creativly instead of having fear of this complicated device a compressor is.

Also, given that it seems to be that the Mystery Box was often packed with the Clean and a lot of people were hoping they get something else it might be that you will find a Clean for a good price on the used market.

For synth-nerds its cool to have a choice today between small and great Comp pedals like this OTO thing, the Polyend thing, the Clean and so on. They all seem to have different aspects and its cool to have those good choices.

Update: I tried a Polyend Press at a friends place. Did not like it tbh.

I now saw in some comments mentioned that Cosmotronic brought out the Messor module in pedal form. I ordered one and cant be happier. For me by far the best (true analog) stereo compressor pedal. Amazing little device

Very transparent compression (meaning it’s hard to appreciate what it’s doing on audio examples), so not a ā€œcolour compressorā€ but a more versatile tool.

Thought the same until i bought a Messor pedal. It can do from transparent tight compression all the way to super mushy analog crush. It is far better imho

I’m surprised to hear the Messor Pedal is done. I was communicating with the dev about it but never heard back. Anyway, glad to hear it’s great! Those transient shaping capabilities - wow!

I think the dev has a lot on their plate.
That said, i had the luck of getting a very early example.

You said it. Also has a sort of ā€žbuild in overdriveā€œ which means the harder you drive the signal and with the right settings you get an overdriven sound and not only compression. A bit like a soft clipper. But it also can sound as clean as a clean plugin compressor.
It is an amazing compressor regardless of money. Also there is a huge difference depending how hard you are feeding it with signal so you also get a great approach on actual gain staging.
I would also say its an incredible way for newcomers to learn compression in a hands on way.
Or maybe it just me and it hits the spot of my taste. It does all that Press, Rnla and maybe even Xpressor (the old, the Neo is awesome) did not do for me

I like the PE Compressor it compresses and doesn’t add tone, etc. which is what I want from a compressor.

Today I realized I can patch the pedal to its own side chain, turning the SC footswitch into a feed-forward/feedback toggle.

Connections:
source->Stereo In

Stereo Out->SC in

SC thru → mixer

if you dont want colour then the EHX Platform is also a great choice.
In my case if i want the most transparent compression i stay in the box tbh

you need a filter in order for a SC to make sense i.e you have to be able to
exclude content or else you will be simply Processing i.e in this case Compressing Full Range in which case you dont need a SC Filter in the first place. These filters are most times as far as i know affecting the SC and do not degrade quality in case someone gets doubts when hearing ā€œfilterā€ and thinks the signal gets dissected or similar. The initial way of doing SC as far as i know was via using an External Equalizer that ā€œcustomisedā€ the signal before hitting the Compressor.

But that is only to my knowledge. Don`t take my word for it as i am no expert

I think there are at least two different approaches that both make sense: Either a compressor uses the signal to be compressed to determine when the compressor kicks in - in this case it makes perfect sense to have a ā€œsidechain filterā€ to exclude certain frequencies from triggering the compressor (this is, for example, the case in the Elysia Xpressor). Or, a compressor allows to replace the internal sidechain with a dedicated external sidechain input (e.g., a kick). In this case, a sidechain filter is less needed (e.g., WMD MSCL).

I did not think of modular at all to be honest.yes in this case of course it makes sense as you say.I was only thinking about studio equipment, so this made my answer a little bit narrow.
In contemporary studio compressors a side chain filter , integrated in the compressor is getting more and more frequent to a point where it’s almost seldom to not have it.

If you’re comparing what I described to plugins, it is the rough equivalent of the New/Old switch on API 2500 style plugins.

It leaves the HPF / LPF controls enabled too, so frequency shaping the trigger signal is still possible.

I am super excited about this discovery. The Press was already a staple in my rig and now I have a whole new ā€œvintage modeā€ to play with too. I shared the tip for other Press owners because it’s an extremely powerful undocumented (as far as I can find) configuration.

I got an email yesterday stating ā€œTHAT corporationā€ are ceasing to produce many of their chips.

One range effected is * 2162, 2180- and 2181-series BlackmerĀ® VCAs, I know these chips are used in many hardware compressors especially in Eurorack as I’ve used them in many builds.

They are giving companies who depend on these chips for their products a last chance to buy bulk by the end of September then no more will be available.

I wonder longterm how many products this will affect as there many larger companies use these chips, and hundreds of DIY and boutique compressors based around the THAT2180/2181 because it’s essentially a purpose-built, very high-performance audio VCA.*

There’s a good chance the compressors mentioned in this thread use THAT chips.

Isn’t it the original input signal that goes out to the thru output? How do you get the compressed signal output with that setup?

That’s right. In feedback compression the level detector is ā€œlisteningā€ to its own output (through LPF/HPF).

Hopefully my chicken scratch helps:

If you try this setup, a simple test is boosting or cutting makeup gain. When you’re in feedback mode, higher makeup gain causes more gain reduction.
