perhaps the befaco instrument interface?

I have read some mixed reviews about the befaco. Maybe I should just try it. Befaco kits are very fun/relaxing to build, and I'm sure I could sell it if I don't like it.

maybe this: https://pushermanproductions.com/product/void-modular-dual-adsr-12hp-pcb-black-gold-aluminium-panel/ for the adsr???

This looks awesome. Compared to the intellijel, I may miss the end of decay trigger a bit. I use it as a trigger delay. I would also miss the cycle switch (though not so much if I had dedicated LFOs). On the other hand, the built in attenuverters look very useful! And, well, LED sliders make me happy.

Thanks for your reply!
