Re: Deckards Dream General Build Thread

One thing I did (in the absence of schematics or even a hint from anyone) when I had issues with one of my 2.1 voice cards alfa build was measured the resistance from different points and compared that to the resistance from those exact points on a different working voice card. That was how I found...

Re: Disapointing Modules

X1l3 Persuadatron - bit of a waste of money. I'm sure its been taken off the market for a reason, which is why its considered rare. That reason is that there's always a lag when using cv. Pretty much fast cv's don't work on it. It only shifts up and down by 1 and only works with gates. The only thin...

Re: Arduino mpe programming

Yes! it works! Fantastic - thank you! - and its so simple (so mpe is just as easy as normal midi). Here's the updated code with initial velocity and poly aftertouch: #define pin0 A0 #define pin1 A1 #define pin2 A2 #define pin3 A3 byte pins[] = {pin0,pin1,pin2,pin3}; const int NUM_OF_KEYS = 4; int in...

Re: Arduino mpe programming

Thanks for all that - I'll check it out.
So I did hear about not using Ch 1 and that is why I add 1 to the channel. I tried a few different things like add 2 or have "int count = 1", but no difference.

Re: Arduino mpe programming

So I've adopted some of Liam Lacey's code from his hackaday blog for the midi: https://hackaday.io/project/11787-vintage-toy-synthesiser Now I am trying to make it work with mpe, but am not having much luck. The issue is that when I hook it up to my Deckards Dream (in mpe mode), each key that I pres...

Re: x1l3 - PERSUADATRON

So I bought this module a while ago. Not sure if there's something wrong with it or I just aren't using it properly, but cv control seems to be weird. Like when I patch an LFO to the Frq- or Frq+, it takes a while of long silence before it switches to the next channel. I can only patch slow LFO's to...

I've even ordered all my tl064s, tl062 and lm13700s without any issues (apart from possibly them accidentally putting a single wrong chip in the tl062 packets and it blew up because I didn't check it ...

Arduino mpe programming

Hi all, I'm trying to work out how to program a midi controller I'm building (using velostat) to send mpe midi to mpe compatible devices. There doesn't seem to be much info online on what the fundamental differences in code are (besides one hackaday article and the linnstrument, but their source cod...

Hey I tried sending you a pm but for some reason it kept bringing me back to the send message page. let me know if you received it. I was wondering if you still had a spare pcb set left.

Re: Doepfer A-180-3 Suddenly fried

I've had this mult for 2 years - it was one of the first modules I bought during my eurorack manic phase. It quickly sank to the bottom of my rack and after it stopped working I hadn't touched it for the past year. I mainly just use those passive portable mults and in some cases MI Links if I need a...

Whats worse now is the pads come off quite easily when I desolder it :doh:

I guess they went for the cheapest lowest quality boards.

Re: Doepfer A-180-3 Suddenly fried

I'm pretty sure I've never plugged output into the output. The only module I have damaged is an A-180-3 - it happened because I inadvertently connected it to the output of a module. I am certain of this because I accidentally did it twice.... :doh: The "sensitivity" of this modules output is due to...

Yeh I definitely checked the power polarity and it was correctly plugged with the red stripe down. Also have never tried to use it as a mixer - I'm pretty sure I've never plugged output into the output. Which is why I'm so concerned - this is the first time an IC just fries like that without me doin...

Doepfer A-180-3 Suddenly fried

So I've had some issues with the Doepfer A-180-3 dual buffered mult since I bought it. It seemed like it was the jacks which I thought was just warped out of shape inside because when I plug a patch cable in, they sometimes worked and sometimes didn't. I didn't think much of it and figured I could j...

Re: Deckards Dream General Build Thread

https://i.ibb.co/Wx3z45Z/image.png So I think I may have found the source of the slider voltage. Measuring about 11.94V on one end of R8 and 4.11V at the other end. On the TL431, I'm measuring 3.2V on pin 1 and 4.11V on pin 3. Anyone know how these shunt regulators work? I did some experimenting by...

Question: Would anyone still have an empty (no components soldered yet) mother board available?

Re: Deckards Dream General Build Thread

Anyone know where the 3.3V is supposed to be coming from on PBD1? I think this is the source of my problem with the pushbuttons (I only measure about 1.5V from pin 1 so must be something blocking it).

Re: Deckards Dream General Build Thread

Silly me. Turns out that this is normal as the 3.3v for the sliders is on a different rail on rev2. So now I got the firmware loaded and the OLED is working. When I enter in a voice card (just a single one), the +5V led is off and -5V and -12V leds on the psu flash slowly meaning there must be some...

Re: Deckards Dream General Build Thread

Which missing smd component? Is your board rev2? The thing is, I don't actually know if the pushbuttons worked, only that shift worked because I was able to go into usb mode to load the firmware but pushing it and turning it on. If you turn it on while pressing shift, do you still enter into usb mo...
