So one conclusion I have made is that this unit is great as a mono voice, but probably not the best to use as part of a poly setup. The envelopes are a bit too limited. I have 4 fully working lil Erebus and think that I need to let 2 of them go. If anyone is interested, pm me, preferably for someone...

I finished my build, all working except VCO2 isn´t doing anything, same issues two other members have. Did anybody solve this? Swap IC 1 and 2 and see if you still have vco2 missing or vco1 missing. You mean the two first op-amp starting from left side (labeled IC10 and 21) ? I ask because on schem...

Have you checked out the lil Erebus? It’s diy. Has plenty of character and not only can you use it as just a filter, you get as a bonus, a full synth voice, 2 osc, a bbd delay... all for a decent price. It has an audio in and control of vcf. I personally love the sound of the Erebus filter.

I just want to summarize some thoughts on the lil Erebus. First, I’m by no means a diy expert. I’d say an average builder with access to my dad, an electronics expert who was able to help trace down each of my four builds’ issues including a bad transistor. And that is exactly my point. I believe I ...

I think this is relevant form the documentation: When I patch something to the VCA , i get no sound -The VCA needs at least 3,5V so as the synth starts producing sound So does this mean that there is full dynamic range for vca, just that I need to start an envelope at 3.5 and go to 5.0? What’s the ...

I've just noticed something that might be helpful to people having midi problems; On my build at least, switches 1 & 3 on the dip switch are transposed , so: midi channel 1 = switch 3 on, channel 2 = switch 2 on channel 3 = switch 2+3 on channel 4 = switch 1 on channel 5 = switch 1+3 on channel 6 =...

Is it just me or is the vca control extremely non linear? It’s hard to coax a smooth decay or release from it, even using external envelopes. At long decay or release settings, the vca stays at full volume then just falls to zero really quick instead having a slow drop in volume. All my units behave...

now that i have been able to fix the envelope, there seems only one issue open with my build: the manual says about the time cv input: "DELAY TIME CONTROL (0V - 5V)" but on my unit, the effective cv range for time cv is +/-1v. there is nothing happening beyond 1v... anybody else getting any delay t...

Throwing out some info that cost me about an hour. Hopefully it helps someone down the line. If you need to replace a TL074CN chip, as much as possible, keep an original from dreadbox in IC1 and IC2. I ordered some Chips online that were called TL074CN, but when used in the osc section, you cant get...

i've finished my lil erebus, and everything seems to be working fine. i love that creamy filter and the very playlable delay section. but the envelope seems to be behaving a little strange in some ways. i'm not sure if these are just some quirks of this envelope design, or if there is something wro...

Bartleby, I’ll investigate your envelope observations a little later today. For now, I finally realized how to adjust the scale settings right. Like morph says, use a tuner app that show exact pitch frequencies. I found that trying to hit a target like 50-100 didn’t work for me. Here is the key for ...

Keep in mind that the Erebus V2 chains for paraphony, not true polyphony.

FYI the connection is broken if you plug into the cutoff jack. https://www.muffwiggler.com/forum/files/eg2cutoff_170.jpg Not sure I’m...
