my dd6 is also heavily modded with gate inputs for the pads, im surprised you didnt add the cv input for the pitch mod. also, alternatively , you can use a hex inverter to flip the gate signal
Yeah I still may a vactrol for CV pitch control. I’m just breaking everything up into separate videos. I’ve also done the hex inverter technique on my DD-5. But wanted to try it this way for a change.
@@SISKworks Using this technique to flip the trigger signal, or just plain old vactrol circuits, i’ve added trigger inputs to all my toys with pads/keys. It’s pretty nice to have everything in sync!
I don’t really remember how the Speak and Spell/Math work. Probably not. This was kinda different because it triggers on the release. You should try an optocoupler. I’ll link a little diagram I made. Super simple. Just (1) resistor and (1) optocoupler IC. An optocoupler is basically a switch that is controlled by a LED. They are very useful for circuit bending. imgur.com/a/vzgxrL8
Dude this is like the coolest channel. I always wondered how to add gate inputs to toys or old instruments.
THANK YOU! I’m trying to put out more videos this year too.
Insane! I modded mine with the pitch, and some glitches, this week i add this mod and it will be finished! Thanks a lot
Can the uncommonly used 1N914 diode be replaced by a more common 1N4148?

@@ned_interrobang I also just bought some optocouplers and will be trying them as trigger inputs on a few other toys next.
Awesome
Can I use the same transistor circuit to trigger the buttons on a speak and math?

Thanks! Your channel has been super helpful.@@SISKworks
Could you do that for the yamaha cs-01 ? ^_^
Do you mean the synth from 80’s? What are you wanting to trigger on that?
to sync it to a drum machine or another analog synth that have the gate out@@SISKworks
@@BarbieChaiteoh I’m not too sure about that.
