Hi all. I’m looking for a modern day equivalent with a similar feel to these organ rocker switches or something close that doesn’t cost a ton of $?

Ideally pcb mounted but I’m flexible

I’m working on a simplified prototype of a synth I built for myself and want it to have a similar feel to an old organ. For my first build I got some used ones of eBay but I need something uniform for scale.

I figure I’m not the first to go looking for these.

Thanks!

This is Paul Stevenson's Devil's Triangle Drone. It was the first one he recommended to me, and I've built it multiple times since then. In my version, I've added an off/on switch, an indicator LED off voice 2's comparator, and shorted voice 3 back into voices 1 and 2 via lug one of the pitch pot. Sound confusing? I swear it's more clear in the write-up on my site. The modifications I've added make a very simple build significantly more "musical", imo.

Dear Community,

I am working on a digital effects module. ESP32-S3 based, 10hp wide.

Its going to be my first time doing DSP stuff and being completely honest: I am so lost when it comes to programming 😅 But I will manage...

I bought an e7 used a couple weeks ago, and my initial impressions were great. Only problem is the Shift button was acting up, but opening it up to diagnose, it seems like a really easy synth to work on. I tried cleaning the part with compressed air and then isopropyl alcohol but the behavior persisted. I didn't want to deal with the return rigamarole for something that seemed very easy to fix, so the seller agreed to cover the cost of replacement parts (they nicely offered to cover the cost of a licensed repair person at first, but there are none near me).

I contacted GSMusic via their website and also sent a message via Instagram a week later. I have heard crickets in the meantime (despite their account liking an unrelated comment I left in the meantime!) and it's been like 3 weeks. At this point, I'm just figuring I'll have to identify and source the parts myself.

So have any e7 owners here had to do repairs themselves? Or anyone who is handy with IDing parts own an e7 and willing to take a look for me? I can open it up and post photos when I get home later today.

P.S. I realize I didn't spell out the problem behavior with the buttons - the "Bank" button is right next to the 'Shift' button on the e7. When the unit powers on, the Shift button is not engaged, but the second you try to push the Bank button or push the Shift button, it stays engaged constantly and will not turn off until the unit is powered down. As you can imagine, this is a pretty big problem. That's why I tried to clean with compressed air, first from the outside, then from all around the switch after opening the unit up. When that changed nothing, I tried taking the button cap off and cleaning the actual metal of the switch enclosure with isopropyl alcohol. Still no dice. So I figured at that point the easiest foolproof fix would be to simply replace the Shift (and probably the Bank button, just to be safe) switch.

P.P.S. Just remembered, the previous owner mentioned sticking a toothpick down between the button cap and the enclosure and jiggling it when buttons would stick and said that would get them unstuck. That's why I figured maybe there was debris or something that cleaning the switch would fix.

"Ciclo Piezole" was my contribution to an art & maker camp - many of the participants are musicians.

The project consists of 6 ESP32 C3 "satellites" (or "leaves") connected via ESP-NOW to one ESP32 S3 that acts as a controller.

Each of the satellites is battery powered and controls either a solenoid switch (for percussions) or a piezo element (for melodic sounds).

The controller has a serial connection to my notebook. I use a simple, self developed protocol similar to MIDI to exchange information like channel (= which of the satellites should respond), note to be played, key velocity, etc..

The input from the MIDI keyboard is translated to this protocol with a python script.

When developing the project I realised it is not possible to utilise the full musical range of 6 satellites at once. Therefore a looping software was developed (also in python) to record a track for each of the instruments one by one. Each track can also be replaced individually so the melody would change over time.

To configure each of the nodes (e.g. select channel), I used PARASOL (a self developed web ui for ESP devices).

In the video you can see a playback of a loop while I zoom to each of the satellites.

It’s not really a synth project, but the community here is so nice and helpful I thought I just repost it here to.

If anyone has a WIMA MKS2, 4.7µF, 50V, 10%, 5mm pitch capacitor they would be willing to part ways with for a reasonable price, I’d love to take it off your hands. Will pay for shipping as well.
