Re: Behringer Go eurorack case

I have two go cases. No noise from either - and they're in my bedroom no more than 6 feet from my head all day. No more Go cases until January for the US. :-( Just got a Go and I can't hear any noise from it either. On the other hand I've never had any of the power related issues that get regular m...

Re: Behringer System 55

Alright, I ordered an 'inexpensive' little compound table for my drill press. I've just been having too much anxiety about screwing up another panel. I just can't see millimeter sized stuff anymore. Then I can proceed on drilling the 911's and my Poly D Bay and get back to making notes. Tomy, I gave...

Re: Behringer System 55

If you *do* end up with a screen printer, be *sure* they're experienced with printing on metal. And over powder-coating if you use that! The huge preponderance of screen printers are doing T-shirts. Wrong inks, wrong screen mesh, and vastly relaxed registration compared to what a decent metal panel...

Re: Behringer System 55

No clue about the popping. Interesting. Perhaps, that pot was particularly poor. I see you went to town on the CP3A-M too. :-) at least when stuff start to fail, we'll have a couple of control groups with different pots :-) the popping was with the stock pots, it's gone with the alpha ones, very pl...

Re: Behringer System 55

well the table you posted showed the 904 filters to have B503's in them, mine had B502's in them, so I used B5K-ones as replacement, I tried B50K on the 904B, but I got some weird behaviour when moving the knob too fast, so I put in B5K's and they are fine now. are you sure your filters came with B...

Re: Behringer System 55

The pair of six legged ICs in the upper middle of your pic could be two tranny pairs.. The three SOT23's and 8pin?? Somewhere there would be a -6V Vreg. So that would account for at least one of these. Maybe. Back on page 22 we went through this module. Pretty sure those were diode packs from the C...

Re: Behringer System 55

I found that 923 can still be a little jerky, I thought the knob would solve this 100% but it solved it about 95 to 90%. also: not sure how to calibrate the filters properly. oh, and I tried the 50k pot on the 904B but it gets jerky with it when rocked hard, needs a 5k one to work properly, is this...

Re: behringer teases...4-note poly Model-D???

If I understand correctly : at position zero the Attack time is 13 ms, just when you move CCW it jumps to 23ms, and after the behaviour is normal ? No, it's more complicated as listed. Imagine, a potentiometer isn't an ideal device. The panel legend is laid out for an ideal logarithmic device. Inst...

Re: behringer teases...4-note poly Model-D???

Update: - Tuning is so easy now with good pots. - 4X timing brings this Poly D into useful attack range*. - Internal Sequencer clock jitter is terri-bibble! I'm building a 16 channel truck bus for a 8HP trunking panel on the Modular. Luckily, they give you a Clock in to the sequencer. It's clocks be...

Re: Behringer System 55

I'm adding a 1/4 inch 14-16 channel trunk into the rear of my System 55, mating to a 16 jack 8hp panel. Why not use the 8 channel audio standard on DB25 connectors? Actually there are two different standards -both using DB25- and one of them would be the typical way to trunk 8 or 16 channels to a b...

Re: Behringer System 55

Can anyone recommend a panel paint and silk screen service?

The upgrades on the Poly D are coming out so fine, I'm adding a 1/4 inch 14-16 channel trunk into the rear of my System 55, mating to a 16 jack 8hp panel. It's quite complementary to the the Modular sound - not surprising :-)

Re: Behringer ARP 2500 modules

Yes Attack and Decay on the 1003 are 05A105. Build feels nice and solid. OK. Then the rest of it, as I've found, is very competent work. I love my modified B55 gear. The Log mod on the Poly D perked it right up too. The ARP2600 has a 0.5X/1X/2X switch added to it* to address the Re-modernizing Vint...

Can you read the part number on the Attack and Decay pots? 05A105 or similar perhaps?

Re: behringer teases...4-note poly Model-D???

I've finished a simple four pot and cap change to shift timing down by 1/4X, plus good ALPHA Attack and Decay pots. This should give about 2-3ms to 2sec of real timing. You still get the 800us glitch attack, which should now be 200us. Still sounds like glitch to me. :0) So, wow! I'm starting to love...

Re: behringer teases...4-note poly Model-D???

Scope confirms same issue as Behringer System 55 911 envelope generator ADR timing. From full CCW you get: - 800us - this is the 'dead short' Potentiometer through 100ohm timing with a 10uf cap. - 800us - 13ms, can't get there from here. ER spec is too high. - 13ms - 23ms, jumpy settings. The first ...
