- My 28th original eurorack modular synth DIY projects.
100 type DSP multi effect module that re-build of my past DIY module.
Although the parameters cannot be controlled, it can be expressed more richly than the PT2399.

I love the look of your White on Gray panels!
Great module I already have the components to build it from when you made the first one! Btw nice techno track at the end!
I'm gonna build this one, got all the parts! Still have the DSP board laying around that I ordered after seeing your vid
subscribed!
I found the kit for much less on eBay/AliExpress/Banggood. About 12€ (15USD?).
Hi Hagiwo👋! Another awesome module! One question though, what is the purpose of the first opamp? And why do you mix the input and output of the effect?
The first op amp has two purposes. The first is impedance separation.
The second is phase inversion. The phase is restored by inversion twice.
I think it will work without the first op amp. (Although it has not been verified with an actual circuit.)
Just got the same module, the program list don't seem to match with yours nor with other program list i found out on the web, weird ^^. Also the mix pot doesn't work quite as expected, it doesn't act as a dry/wet pot, it just adjusts the effect volume, a bit disappointing, i think i will bypass it and add a proper dry/wet mix pot.
do you have the link of the dsp board with mix control ? i only find the one with volume control
where can I find pcb? (and display?) or kit?
Hello, please tell me what voltage you have at the input of the FX board and at the output ..? I noticed that if you put more than 0.7V into the input of the board, then there may be distortion on some effects ... but my board is a little different. What do you think about this?
It is possible to distort above 0.7V. As a countermeasure, I have installed an attenuator just after the INPUT terminal on my module to reduce the input voltage.
@@HAGIWO yes that's right, thanks for the reply.
