wow! can you switch audio with these? eg to make circuit bends sequenceable?

can you switch audio with these?

yes. it would be an interesting experiment. but i used the MBHP_4066 board just for MIDIfying a Yamaha VSS-200 yet (for interfacing the keyboard keys and the buttons).

Great. Nice project!

I have been using 4066 to trigger some of my bend devices. The 4066 controlled from analogue sources: Gates and Triggers from analogue synths or MIDI-CV converters.

I’d be interested on building and trying one of this. Are you using a custom MIOS application to control the VSS-200?

i’m working on a MIDIBox VSS200 application (core8, asm):

it’s work in progress :slight_smile:

I don’t know how these would go switching the negative cycle of audio signals. Normally when switching audio with a 4066, a DC bias is added to the input so the negative voltage is higher than the negative supply of the 4066.

If you wanted to use larger audio signals like in a modular synth I’d try the DG211 chip instead. You would need a bipolar power supply though.
