Sorry, I don't quite understand. Are you looking for a signal function generator kit? Or a circuit to switch between multiple inputs and/or multiple outputs?

Hi dudu,
Do you want the signal to pass through IC's, transistors or relays? Relays would sound the best without great care in design.

if I could to suggest
better choose relays, thae are almost distortionless.
ICses will distore the clean sound sound up to 0,01%THD.

Anyway I am interested too.

I think that the problem will be solved if anyone could design good switching and steering circuit.

I thought many times about it.
... And my problem is only how to steering the relays from a "momentary switch-contacs".
To explain: how to steering from the switches that are not in type "switch on - switch off" but only from the short contact when pressed?

How about 'T'-flip-flop with short impulse to clk input?

Cześć
proszę jaśniej

Sorry for this part, I have to explain:

chodzi mi o coś takiego: jest 5 styków (styków, nie przełączników). Jak zbudować układ, który po chwilowym zwarciu jednego ze styków włączy włączy dołączony przekaźnik? Może być dodatkowo układ pamiętający stary wybór po włączeniu zasilania.
Jeśli to się nazywa T flipflop to jestem za

Thank for understanding!

sorry for Polish

rozumiem
nie wiem jak zrobić, żeby pamiętało, ale pomysł mam taki:


This is an idea for 4 inputs with D-flip-flops.
The circuit is not idiot-proof, I mean pressing two at the same time can short inputs:

EDIT: not built yet, only suspect it 'should' work.
any comments most welcome
