Anyone know where to order some cheep 1503-09 jacks? I tried to order Reichelt EBS 35 but Reichelt is not delivering to the US. I need 24 at least for some VCAs.

If I cant find them cheap I may just order different pcbs that use thonk jacks (Cause I have a ton of those)

Also have other pcbs that use Dual 2164 VCA submodule but they also seem out of stock everywhere.

If anyone knows some simple duel VCA they successively built from git hub that would help as well... because I'm 0 for 2 here.

have to set all my trim pots, but all the modules are playing nice!! v happy with my fancy night light

Después de varios años de búsqueda, la aparición de la IA me ayudó a desarrollar una solución para mi necesidad de un editor,/banco de Presets-Timbres para estos dos sintetizadores. Están super completos y vienen hasta con su manual. Todo está a vuestra disposición de manera 100% gratuita (por ahí invítenme un cafe en el link si les mola).

I wanted to add more external sounds to my drum machine so I made a piece of gear that can sync any audio source. It has 8 inputs that run through individually controlled analog switches and then mix together and go through an optical VCA. The switches can be controlled by a built-in sequencer or by a connection to the drum machine. The built-in sequencer has two modes, one is sequential like a multiplexer and the other uses a binary counter chip to mix all the signals together. The VCA CV input takes in the audio from the drum machine or any other source and uses its envelope to modulate the output of the mixer. The envelope can be inverted with a switch to give an effect like side-chain compression.

Or as unpatched as it gets...

Hey community,

I’ve built a toolchain for developing custom effects for the MS-70CDR pedal series. At this point, the pedals can basically be treated as an open-source coding platform. Right now I’m porting Chris Johnson’s Airwindows plugins step by step.

“Stereo Chorus” is already up and running, sounding flawless so far.

If you want to contribute ports or simply download and use the FX, check out the GitHub repo:

https://github.com/repeat98/ZoomMultistompZDL

Custom ZDL support will be coming with the Zoom Effect Manager 2.3.3 update.
Spread the word, so we get more developers on board to make more FX.

Also, if you have suggestions for effects you’d like to see, leave them in the comments.

Cheers,
J

You guys post the most beautiful looking gear. Say hello to my very first DIY synth. It’s housed in a cheap plastic box I salvaged from the trash at work.

I took one semester of hands on electronics education back in college, but that was aeons ago, and I barely passed the class. Cut to nearly a quarter century later and I have all this extra brain RAM after cutting the booze. A new obsession has been born! Cheers

The LEDs above the bottom white 1-16 buttons on my RM1x stopped working. 1-8 sorta dimmed out over a week or two, now I get no lights. Can anyone provide guidance on whether a noob may be able to repair this? Or what may be needed?

I’ve been working on a new midi controller design for about 6 months. It’s a simple, small two knob controller with 4 midi channels and 3 sensitivity options for two midi channels.

Here is a quick description of how it’s used

Turn - primary control
Click - primary control sensitivity
Click and turn - secondary control
Click and hold - turn LED on/off

If you have any questions, hmu :)

I rack mounted this DW-6000 about 10 months ago, just returned to it to do some bug fixes and replace the pots and mux chips with encoders and io expanders. It makes editing so much easier as each parameter is at the correct position.

Details are here. https://github.com/craigyjp/Korg-DW6000-Editor-Encoders

Introducing the AMYboard, available today - a US$29.90 (!!) synthesizer for your standalone synth or DIY projects. You've seen and loved the Tulip, the Diapasonix, the Spark, all made with our AMY synthesis engine! This is a complete board with jacks for running AMY, with audio in and out, S/PDIF, 2 CV channels, MIDI, SD card.

AMY is an excellent recreation of 80s and 90s analog and FM synths with an online web editor for patches, effects, and code sketches (in Python), or Arduino for your own firmware. Fits in a 10HP eurorack slot with 12V power if you want, or just use USB 5V, or over 3.3v I2C. Make an amazing synth!

Hi,

I'm trying to prototype a SVF-filter with a moprhing control from a single potentiometer. The idea is: When pot is at one end only the LP output is active then at the midpoint mostly BP and at the other end only HP. I'm having some trouble getting my head around the right polarities for the precision rectifiers here. I used this article as a reference: Precision Rectifiers. I would appreciate if someone more experienced has a look at this schematic for things to fix/improve! I'll be using the three generated CV's to control a SSI2146 VCA with the different filter outputs.

Thanks!

EDIT: For clarification I'm especially unsure about the orientation of the rectifiying diodes D12-15.

I just bought a PALMER piano (ELECTRONIC PIANO PP-73 II). When I press a key, it makes a muffled sound, but doesn't produce any notes. I checked and found that the tone control had a broken wire in the capacitor.After fixing that wire, it still hasn't produced any notes... Before anything else, it had an annoying hissing sound, and I identified that it could be a grounding problem. I connected the grounding wire to the VOLUME Along with TONE, the hissing stopped, but it still doesn't emit any sound... Does anyone have any idea what I can do at home?Sorry for my English, I'm from Brazil..
