The Synthrotek Expression Slider is Awesome!

I remember seeing a demo of this gadget a couple years ago. I found this red fader knob and it gave me the idea to build one. It's basically a hand-controlled expression pedal. I really like the way the project came out and the device is surprisingly useful.

Well I've learned something today. I think the closest I've come to an expression input is a 1/4 inch jack on my piano, but expects just a simple switch for a sustain pedal. When I read the title I expected this to be a midi CC slider. I had no idea that some instruments have an input expecting a potential divider. You made a very nice job of the case. I wouldn't be bold enough to go for red, but the paint job and the red knob make this look really smart. Synthrotek should make that an option.

Ah yes. It's a fun realization that an expression pedal is just a potentiometer with a treadle. Here's another fun fact. If you take an inline volume pedal (like you'd use for your guitar), get a TRS to dual-TS cable, plug one TS into the pedal's input, plug the other TS into the pedal's output, and bam... expression pedal. So effectively, every volume pedal is also an expression pedal. 🤯

@@musicalmiscellany still trying to get my head around that but that does sound like a fun hack.

That does look quite sharp! Expression rampers are really useful, especially for non keyboard synths. I currently own 2 pedals that you can use one with, and they are both pedals that i have no interest in using an expression device with.

I completely agree. It's a weird thing but sometimes you just don't want to mess with a foot pedal but a slider seems more intuitive. They're effectively the same thing but there's a time and a place I guess.

Fantastic channel bro .

[@musicalmiscellany]

I really appreciate that. Thanks for taking some time to watch the vids. I've got a lot of them.

I think I could do this!! I did the korg S-1 and also the Moog Can’t remember the name. But it was replaced by the Mavis. That might be a good project to get my left hand going again !! Thanks Kale and I would use it with the different synths I think. Very cool

[@musicalmiscellany]

I’m sure you could handle it. This is one of the simplest projects I’ve ever built… but it’s surprisingly useful. Thanks for checking out the video.

[@MariaCalfaDePaul]

@@musicalmiscellany Your’re welcome. And thanks for the encouragement. !!

[@musicalmiscellany]

@@MariaCalfaDePaul This would be a great project for someone looking to hone their solder skills. It's relatively cheap and quick to build.

[@MariaCalfaDePaul]

@@musicalmiscellany thanks. We do have that soldering iron now lol (Vinny used it to replace the toggle switch on my inexpensive Epiphone electric I won )

This might be useful with my Boss SY-1 guitar synth pedal. I've found a regular guitar expression pedal to be too imprecise for my taste in this situation.

[@musicalmiscellany]

Yeah. That's one of my favorite things about this gadget. It's really precise. Thanks for checking out the vid.

[@bearshield7138]

cool

[@musicalmiscellany]

Fun gadget. Thanks for checking it out.
